I have a 98 Jeep Wrangler and I upgraded the headlights to LED bulbs. Since then, I've been battling to get my headlights to turn on at night. They don't flicker, they stay on once they come on, and they seem to be getting enough power to run them. If they aren't turned on at all, the high beams don't work as well, but they function as intended as soon as the lights come on. At first I thought it could be related to cold weather as it was particularly bad during the winter, but now half way through the summer, they are still having the same issue. Running lights and the instrument panel lights come on and I even replaced the headlight switch thinking that could be the issue, but it didn't improve the situation. I have noticed that banging on the steering wheel makes the lights turn on, but I don't know what relevance that has to the headlights. Maybe the dimmer switch? It seems like some electrical issue, but they never flicker when I drive so I don't think it could be a bad ground or anything loose in the harness. Any ideas are appreciated. Thanks
