here is my homemade headlight and how I mounted my flashers. I plan on adding more reflective tape. I ordered some black that will match the bike.
the headlight is homemade. it uses a car fog light (mr16 based halogen bulb. I have some nice looking mr11's too) I use a 35 watt solux bulb. it has a slight blue cast to try to be a 4100k color. it is pretty white looking and very bright. brighter then a HID setup. though it sure sucks the juice out of cells and I only get about 1.5 hours runtime. but that's all I need so I can get away with a larger light. no car can miss this light and I bet I blind a few drivers (G) I could even overvolt it to 16v and really blind everyone. but UFO's tend to attack me when I do it.
on back is a sparky xenon flasher and a new Cateye rear light. it has LED's on the ends for great side visibility. you have two separate controls so one line can flash the other can be solid. I just used a piece of PVC pipe with reflective tape on it. so far with this setup on my bent and before on my road bike I have less problems at night then in the daylight.
