About two weeks ago on a cold damp night (sound like a good murder mystery opening line! ) I noticed that my headlights seemed very dim. After driving a while they flashed bright a couple of times and then stayed bright. Since then I notice on similar nights that the passenger side lamp seems to be going on and off as I drive. I tried to recreate the problem sitting in the driveway but cannot. I am new to HID technology so can anyone tell me what is happening here? On cold nights (not damp) I dont see the problem as much.

Thanks for any help!

 

try disconnecting the neg. battery term in trunk then go up front to the lights and see if any moisture is getting to the sockets . you could put some dielectric grease on the socket joint .

 

It is either a loose connection some where or the beginnings of a ballast going bad. I'd vote more for improper connections some where. If you pull the lamp make sure to try and not touch it with your fingers. The oil on your hand can lead to premature failure of some HID lamps. And, note that die-electric grease promotes electrical continuity. If if connects both terminals of the lamps it will cause a short and probably fry the ballast.

 

Sorry, you are incorrect. Dielectric grease is not a conductor. It's useful for keeping out moisture and oxygen, but it does not conduct electricity or promote arcs, tracking, or otherwise short out connections.
Don't take my word for it, five minutes with google will convince you better than I ever could.
