Howdy do? I want to mod my truck with some christmas light strings. I have an amp right behind my seat, so I figure the amp is a great place to get power for the lights. But the amp is 12 volts, and my house lights reguire 120v so I cant just splice them in there can I? And the battery powered strings are like 6v, so how would I step down the 12v input from my amp to the 5v that the battery powered lights need? What resisters and how many would I need to solder in to get it done?
Here is a paint picture of my car and what I want to do, help me guys, I want to feel festive.

Actually, 1 AA battery is 1.5 volts.arrowhead wrote:Yeah, 1 AA is 2.0 volts, and the lights that are battery run take 3xAA=3x2=6volts.
So I need to cut the 12volts from the amp into 6volts so the bulbs dont burn out.
Light bulbs themselves are not voltage-dependent. See, light bulbs are like resistors, the voltage in does not matter, as long as there's enough resistance in the circuit to dissipate the voltage coming in without overheating the resistors (and causing them to "burn out"). This is all basically coming from my experiences in High School Physics (last year, where we took light bulbs, and hooked them up in circuits with varying amounts of electricity (from 0-12 Volts DC, and 0-12 Volts AC))
