I had 4 of these in red and 4 in yellow sitting around doing nothing so I gave them a job under the gas tank. I really need to get a tripod as it is really hard to hold the camera steady during the 1.25 seconds the camera is taking the picture. I installed 2 reds ones on either side of the air filter housing and the 2 yellows are on the ends of the tank. The pictures just don't do it complete justice but close enough.

The LEDS are wired in 2 parallel circuits and run to a micro switch then to a 3 amp fuse and finally to the accessory plugs in the headlight housing.

The micro push button switch is 3M taped right behind the left front fork in that hidden area. I just reach up in there and "flick it" on/off as needed. 

 Here is a site with a few switches.   action-electronics.com

 I always use the 3M Auto Trim Tape to mount these units with. It is the tape that has the red backing on it. It is more expensive that other types of double sided tape but it holds year round. The cheapest place I have found it is as Home Depot. It's a bigger and wider roll for less cost than from Pepboys. When mounting the LEDS, make sure to take an alcohol wipe and wipe the area where you intend to mount the LED. The best thing about using tape as opposed to glue is that you can move them around if you want and if your wiring harness has a service loop in it. (A service loop is extra wire that you didn't cut off but rolled it in a loop or snaked it back up under the tank or whatever)
