I recently put Xenon HID's in my Max and they worked great for 4 months or so. Not until today I realized my driver side bulb was out. So I turned my lights off then back on and noticed the bulb tried firing for a split second, but didnt come on. I turned the lights off an on a few times then the bulb stayed lit. this has happened twice today. Any ideas on what it may be? If it were the bulb, it wouldnt try firing at all...correct?

 

this happens on the fogs without the relay on the headlights it means the ballast is on its way out.

 

Thanks man. Ill get hold of the company I got it from. 5 year warrenty!

 

my guess is that the connection is loose. It is always good to start diagnosing the simple first

 

iv had hids last 6 years the ballast is probably bad if it tries to flicker on and goes off and comes on after a few tries.

 

This shows the quality of your ballast. Though it is an old thread, I also faced the same problem last month. I went to a local dealer, he said the ballast is the problem. He asks me to change it or the problem continues.

I searched through google and find a site named sparkhid. There I bought a guaranteed HID ballast and they helped me through out my installation also. Great site
