I had hid's for a few years with no prob but when one burnt out I decided to buy a pair of 9004 HI/LO (hid low beam & halogen high beam) and my problem lies that when I switch on my high beam, the halogen), it flickers for about 5-7 seconds and then goes completly out. the low beam hid work just fine. Just having a problem with no answers for the high beam.

My ballasts are 35 watts and I do not have a relay harness. thanks

 

You need a bi-xenon relay harness.

 

Even though only one bulb is hid which works fine? It's the halogen that flickers.

 

I believe so.
