HID Headlight Problem...
 

I just replaced my two D2S HID headlights and am having a problem.

At first my left light started to pink out and then would eventually turn off, the normal way the HID bulbs die. So I decided to buy two new bulbs from ECStuning.com and just replaced them. Now when I turn on the lights they both light up for a good 30 seconds and then they go dark, not just the left but the right as well.

Anyone every seen this before or know what it could be? Thanks.

Sound like an issue with the ballasts - how old are the headlights (not the bulbs)?
