General H4 Information
These 2-filament bulbs with
P43t base are for high/low beam headlamps and are considered the "stock"
bulb for motorcycles 9 out of 10 times. The H4 was the world's first
2-filament halogen automotive bulb. It was introduced in Europe in 1971,
and was used in many millions of European and Japanese headlamps starting
in that year, but wasn't legalized in the US (where it was designated HB2
or 9003) until over two decades later, in 1992! The
bulbs are not coated with blue, yellow or purple in any shape or form.
They are the best technology in a legal format which meet OEM specs as
well as Government Regulations.
There are so many
facts to consider on bulbs with all the hype out there, no wonder people
are confused and make the wrong choices.
Some bulb makers are just flat
out lying about be "approved this" and DOT approved that". DOT does not
approved anything...
HID bulbs
sold without a specifically designed reflector are illegal.
"Oh that law was rescinded"..... no.
FMVSS108 is undergoing a
rewrite, but the contents of the regulation will not change *at all*. The
rewrite is strictly a reorganization of the regulation to make it easier
to read. NHTSA has not rescinded the law requiring headlamps meant for a
particular type of light source to use only that light source; what
they've done is re-interpreted the regulation so that any company can make
a headlamp system that uses any approved light source for any
application, as long as that system they make is fully compliant with all
applicable requirements.
So then one can say yes a
complete headlamp system is the bulb with a matched reflector which
conforms to DOT standards and specifications is legal. Consequently, buying
a random Chinese HID bulb and ballast off EBAY will not get you a legal
setup.
Finally, there is not a
reference anywhere, which states you can't put an approved HID in
motorcycle. It's finding one that fits is the problem. I have a 7.5" can.
:(
It would
appear that the Federal Regulations on high wattage bulbs does not
specifically dictate a Standard Wattage bulb for motorcycles.
Interesting huh? What it does talk about is called, "photometric
specifications", in section S7.9, which really seems to deal with
measurements of light at different degrees of angle, as in up a degree or
left 2 degrees then left again another degree, or in other words, "that
damn bulb is too bright your burning my retinas!!!! your not in
conformance!!! You go now!! But it does not reference wattage anywhere.
It seems to boil down to interpreting FIGURE 32, shown below, which is the
candela output of a bulb and how it is aimed. It's not the
brightness as you see going away from your headlight out to the darkness
it that is illegal, its the visual representation of your bulb to the
on-coming driver that dictates the law. What I don't understand is how a
60/55W +50 like I am running fits on the Figure 32 chart. I don't have
access to all the test result numbers GE has.
The problem really lies in
2 areas,
#1 The information for
Federal Regulations are in numerous sources and I could not find all of it
and what I did find was confusing.
#2 Even if you could say,
"this is a legal bulb", and could develop a checklist of what makes a bulb
legal, you can't find the technical information from the bulb makers
to back it up.

headlighting
system that conforms to
S7.9.1(b).
S7.9.3
The
upper beam of a multiple beam headlamp designed to conform to the
photometric requirements of Figure 32 shall be aimed
photoelectrically
during the photometric test in the manner prescribed in SAE Standard J584
OCT93 Motorcycle Headlamps.
S7.9.4
Motorcycle
headlamp modulation system.
(If any authority ever gives you crap about your headlight modulating you
can sound like you belong on Boston Legal...Denny Crane, I got mad
cow...sorry, I love that show.
S7.9.4.1 A headlamp on a
motorcycle may be wired to modulate either the upper beam or the lower
beam from its maximum intensity to a lesser intensity, provided that:
(a) The rate of modulation
shall be 240 ±40 cycles per minute.
(b) The headlamp shall be
operated at maximum power for 50 to 70 percent of each cycle.
(c) The lowest intensity at
any test point shall be not less than 17 percent of the maximum intensity
measured at the same point.
(d) The modulator switch shall
be wired in the power lead of the beam filament being modulated and not in
the ground side of the circuit.
(e) Means shall be provided so
that both the lower beam and upper beam remain operable in the event of a
modulator failure.
(f) The system shall include a sensor mounted with the
axis of its sensing element perpendicular to a horizontal plane. Headlamp
modulation shall cease whenever the level of light emitted by a tungsten
filament light operating at 3000 °Kelvin is either less than 270
lux
(25 foot-candles) of direct light for upward pointing sensors or less than
60
lux
(5.6 foot-candles) of reflected light for downward pointing sensors. The
light is measured by a silicon cell type light meter that is located at
the sensor and pointing in the same direction as the sensor. A Kodak Gray
Card (Kodak R-27) is placed at ground level to simulate the road surface
in testing downward pointing sensors.
(g) When tested in accordance
with the test profile shown in Figure 9, the voltage drop across the
modulator when the lamp is on at all test conditions for 12 volt systems
and 6 volt systems shall not be greater than .45 volt. The modulator shall
meet all the provisions of the standard after completion of the test
profile shown in Figure 9.
(h) Means shall be provided so that both the lower and
upper beam
function at design voltage when the
headlamp control switch is in either the lower or upper beam position when
the modulator is off.
S7.9.4.2(a)
Each motorcycle headlamp modulator not intended as original equipment, or
its container, shall be labeled with the maximum wattage, and the minimum
wattage appropriate for its use. Additionally, each such modulator shall
comply with S7.9.4.1 (a) through (g) when connected to a headlamp of the
maximum rated power and a headlamp of the minimum rated power, and shall
provide means so that the modulated beam functions at design voltage when
the modulator is off.
(b) Instructions, with a
diagram, shall be provided for mounting the light sensor including
location on the motorcycle, distance above the road surface, and
orientation with respect to the light.
S7.9.5 Each replaceable bulb headlamp that is designed
to meet the photometric requirements of paragraph
S7.9.1(a)
or paragraph S7.9.2(a) and that is equipped with a light source other than
a replaceable light source meeting the requirements of paragraph S7.7,
shall have the word "motorcycle" permanently marked on the lens in
characters not less than 0.114 in. (3 mm) in height.
S7.9.6
A
headlamp system shall be installed on a motorcycle in accordance with the
requirements of this paragraph.
S7.9.6.1 The headlamp system
shall be located on the front of the motorcycle.
S7.9.6.2 (a)
If the
system consists of a single headlamp, it shall be mounted on the vertical
centerline of the motorcycle. If the headlamp contains more than one light
source, each light source shall be mounted on the vertical centerline with
the upper beam no higher than the lower beam, or horizontally disposed
about the vertical centerline and mounted at the same height. If the light
sources are horizontally disposed about the vertical centerline, the
distance between the closest edges of the effective projected luminous
lens area in front of the light sources shall not be greater than 200 mm
(8 in.).
(b) If the system consists of two headlamps, each of
which provides both an upper and lower beam, the headlamps shall be
mounted
either
at the same height and symmetrically
disposed about the vertical centerline or mounted on the vertical
centerline. If the headlamps are horizontally disposed about the vertical
centerline, the distance between the closest edges of their effective
projected luminous lens areas shall not be greater than 200 mm (8 in.).
(c) If the system consists of
two headlamps, one of which provides an upper beam and one of which
provides the lower beam, the headlamps shall be located on the vertical
centerline with the upper beam no higher than the lower beam, or
horizontally disposed about the vertical centerline and mounted at the
same height. If the headlamps are horizontally disposed about the vertical
centerline, the distance between the closest edges of their effective
projected luminous lens areas shall not be greater than 200 mm (8 in.).

Now here is the kicker, here
in Tennessee, we don't go by ratings or published specifications. This is
directly out of the law books, we go by
glare... and that's it. So
basically it is at the discretion on the part of the LEO whether you are going
to get sited or not. So this means my chances are greater of a citation by
and older LEO than a younger one because of how our sensitivity to light
changes as we age. Contacts or glasses also change you glare response. Is
this fair? No, it is wayyyyy to fluid for me.

Headlamps on motorcycles - Penalty.
|
|
| |
(a)
Every motorcycle shall be equipped with at least one (1) and not more
than two (2) headlamps. |
|
| |
(b)
A violation of this section is a Class C misdemeanor.
|
|
| |
[Acts 1931, ch. 82, § 15; 1937, ch. 245, § 5; 1941, ch. 121, § 1; C.
Supp. 1950, § 2700.16 (Williams, § 2695); T.C.A. (orig. ed.), §
59-906; Acts 1989, ch. 591, § 113.] |

Lights required on motor vehicles - Exceptions - Regulations as to
color, type and visibility distance.
|
|
| |
(3)
No spotlight or auxiliary lamp shall be so aimed upon approaching
another vehicle that any part of the high intensity portion of the
beam there from is directed beyond the left side of the motor vehicle
upon which the spotlight or auxiliary lamp is mounted, nor more than
one hundred feet (100') ahead of such motor vehicle. |
|
| |
(b) (1) Every motor vehicle shall be equipped
with two (2) red tail lamps and two (2) red stoplights on the rear of
such vehicle, and one (1) tail lamp and one (1) stoplight shall be on
each side, except that passenger cars manufactured or assembled prior
to January 1, 1939, trucks manufactured or assembled prior to January
1, 1968, and motorcycles and motor-driven cycles shall have at least
one (1) red tail lamp and one (1) red stoplight. No non-emergency
vehicle shall operate or install emergency flashing light systems such
as strobe, wig-wag, or other flashing lights in tail light lamp,
stoplight area, or factory installed emergency flasher and backup
light area; provided, however, that the foregoing prohibition shall
not apply to the utilization of a continuously flashing light system
on a
motorcycle. For the purposes of this
part, "continuously flashing light system" means a brake light system
on a
motorcycle in which the brake lamp
pulses rapidly for no more than five (5) seconds when the brake is
applied, and then converts to a continuous light as a normal brake
lamp until such time as the brake is released.
|
|
(2)
The stoplight shall be so arranged as to be actuated by the
application of the service or foot brake and shall be capable of being
seen and distinguished from a distance of one hundred feet (100') to
the rear of a motor vehicle in normal daylight, but shall not project
a glaring or dazzling light. |
|
| |
(3)
The stoplight may be incorporated with the tail lamp.
|
|
| |
(c)
Each lamp and stoplight required in this section shall be in good
condition and operational. |

Headlights on motor vehicles - Operation during inclement weather -
Violation - Penalty - Costs.
|
|
| |
(a)
The headlights of every motor vehicle shall be so constructed,
equipped, arranged, focused, aimed, and adjusted, that they will at
all times mentioned in § 55-9-401, and under normal atmospheric
conditions and on a level road produce a driving light sufficient to
render clearly discernible a person two hundred feet (200') ahead, but
shall not project a glaring or dazzling light to persons in front of
such headlights. Such headlights shall be displayed during the period
from one-half (1/2) hour after sunset to one-half (1/2)
hour before sunrise, during fog, smoke, or rain and at all other times
when there is not sufficient light to render clearly discernible any
person on the road at a distance of two hundred feet (200') ahead of
such vehicle. |
|
55-9-408.
Headlights complying with prohibition against glaring and dazzling
lights - Anti-glare devices - Mounted height of lamps.
|
|
| |
Headlights shall be deemed to comply with the provisions of §
55-9-406, prohibiting glaring and dazzling lights, if the headlights
are of a type customarily employed by manufacturers of automobiles and
in addition are equipped with some anti-glare device approved by the
department of safety; provided, that the department shall not approve
any anti-glare device, or any combination thereof, unless it has been
submitted to a laboratory test and has been found, when properly
adjusted, to prevent any of the bright portions of the headlight beams
from rising above a horizontal plane passing through the lamp centers
parallel to a level road upon which the loaded vehicle stands and in
no case higher than forty-two inches (42"), seventy-five feet (75')
ahead of the vehicle.

Inspecting and testing lamps emitting glare - Order to remove illegal
lamps - Arrest of drivers.
|
|
| |
(a)
Any member of the highway patrol having reasonable ground to believe
that any headlamp or auxiliary driving or fog lamp or any device
subject to approval upon a vehicle emits a glaring light as defined in
§§ 55-9-406 and 55-9-408, or otherwise fails to comply with the
requirements of this part, may require the driver of such vehicle to
stop and submit such lamp to an inspection or test.
In the event any such lamp or device is not of the type which has been
approved by the department, the officer making such inspection shall
require the driver of such vehicle to remove such illegal lamp within
twenty-four (24) hours, and may arrest such driver and give the driver
a notice to appear, and may further require such driver or the owner
of the vehicle to produce in court satisfactory evidence of the
removal of such illegal lamp. |
|
| |
(b)
In the event any headlight or auxiliary driving or fog light of a type
which has been approved by the department, by reason of faulty
adjustment or otherwise, emits a glaring light as defined in §§
55-9-406 and 55-9-408 or otherwise fails to comply with this part, the
officer making the inspection shall direct the driver to make such
light or lights conform to the requirements of this part within
forty-eight (48) hours. Such officer may also arrest such driver and
give the driver a notice to appear, and further require the driver or
the owner of such vehicle to produce in court satisfactory evidence
that such light or lights have been made to conform with the
requirements of this part.
