Today I was driving around and wanted to flash someone b/c they almost caused an accident when I noticed that my High Beam didn't come on. I'm running the 9007 conversion harness with Sylvania Xtravisions. I followed all the instructions which included changing the ground and low beam wire on the old 9004 socket on the drivers side. I had this kit in for about 3 months and sparingly used my high beams. I checked the filaments and they look fine, no breaks. I noticed when I turned on the lights and than tried to switch to high beam I would hear a click from the relays. Could it be possible that my relay is blown? What else could cause my high beams to go suddenly. Thanks.

 

Wire connections, relays, anything really.

Not something very easily diagnosed over the internet. Check all of the connections especially where they ground and brights were swapped.

 

I'm going to check all the wires thanks. I was just hoping someone may have had the same similar information. Thanks Spig

 

Like Spig said check all wiring connections and any where it may have rubbed through the coating. Also Ive run into problems where it looks like a good bulb and nothing blown but its a small small break in the filiment and wont light the highbeams.

 

I fixed it first thing this morning. One of my many tasks today. There was a wire they got loose from the relay to the positive terminal. I just spliced them back together. I can't believe I didn't see this last night. But than again it was dark with a small flashlight.

 

lol. I always find myself doing mods at night. A bad habit of mine.
