hey guys,
Has anyone ever had their headlights go dim for about 1 second then right back to normal? It almost looks like if you put a load on them just for a second. It happens going down the highway or just cruiseing around. No pattern, just does it then it's over, and it will do it a few times in a 20 mile drive. Does it every morning going to work. I have checked the grounds on the frame up front on both sides and they are all clean.

Thanks for any help.

 

That's a good one. Did you ever watch the voltmeter when it does this to see if there is a drain somewhere? It would be a good place to start. Kinda hard when it only does it for a second but if you could catch it, it would tell you if it's in the lighting system or a problem with something else. If you can't watch for it have a passenger watch the numbers steady while you watch the road.(recomended) Good luck
