Hi all, I am a relative newbie to the electronics world and I have a project I want to do but need some direction. I have an 1/8th scale remote controlled nitro buggy. I want to add some lights to my car but I have a few factors that need to be addressed. I have already put 2- 3.6v led's in the front for headlights. No problems there until I added a few lower voltage bulbs as tail lights. Contrary to what the "professional" at Radio Shack said, I can't run all the lights from 2 "AA" batteries.
What I would really like to do is have the headlights & tail lights on one switch and a light bar on top of the car with probably 4 more lights on a separate switch. My biggest problem is that I am very limited for space to mount multiple power supplies. I was wondering if it was possible to use a 9 volt battery to power everything? I'm sure I need resistors or something but I don't know how to calculate what size I need. I really don't even know for sure if what I want to do is possible. Will a 9v battery be enough for 6-3.6v led's and 4-others that are a lower voltage bulb? How long would it burn the led's before the battery runs out?
Any help you can give me will be greatly appreciated. I have done a lot of electrical work on residential homes so the switches and everything aren't a problem.
