The light may be the problem, of you might have gotten a faulty one, I have. Before you take it out and exchange it though, check all your fuses, and wire connections in the light housing. A frayed wire, wire connector or a ground wire coming lose would also do it. To find the ground, just look for a single black wire (sometimes green) screwed to a metal surface. They're usually close to the power wires. And if you're going to have the light housing open anyway, maybe try the old bulb again as well as a different new one. Hope I helped. Grimm
