I'm piecing together my headlight right now (20W halogen, 7Ahr SLA), and I need to figure out the rear light. At the moment, I have an old 5 LED red flasher, which is kinda dim today given where LED's have become. I'm tempted to run say a solid 2W halogen rear light, and some sort of LED flasher. My thought is, I don't need a high end flasher if I have the bright rear facing solid light--the flasher gets attention, and the solid light points out where I really am. Any suggestions?
