Voltage divider SOLVED
Would this work? I have a 1 mil CP, 6 volt spotlight bulb. Will a simple voltage divider using a couple of 100 ohm resisters work from my 12 volt lighter recept. in the dash? Here is a better diagr...

It would work only if your bulb used little or no power. Once you put a big load on that circuit, the 6v+out voltage will be close to zero, and the resistor on the 12v+in will be dissipating about 1-1/2 watts. If you chose the correct series resistor to give you 6 volts at the bulb, the resistor would dissipate the same amount of heat as the bulb, so it's not very practical. Two bulbs in series would work, or maybe this is a good application for one of those ebay dc-dc converters that have been talked about on the forum recently.
