I was looking at the pitiful yellow tint of the dome light in my truck, and I got an Idea. I have seen several dome light mod kits for cars, but they all seem overly complicated. Could I take a downboy probably 917 or 1000, and heat sink the Star and driver to a piece of aluminum and hook it directly into the car power lines for the bulb? I think that a down bow is rated at 16V maximum. My dome light is never on for very long.
