I have a 14Wh 12V Lithium battery that I am using to power a homemade 12v 20w headlight for my bike. It's a low rider 3 wheel recumbent and for some reason that headlight is not enough to alert joggers that something is coming in their direction. I theorize that they tune out white lights since the path is along a busy road. So, I bought some green LEDs from superbrightleds (10 B-G, rated at 12vdc and 19ma on their site).
I want to run them off the same battery but if I put them in parallel to the headlight I'm going to have to add resisters to each LED to balance with the headlight. Battery killer for sure, I'm thinking. There has to be something more elegant. Any suggestions?
