Hello,

I have a '99 996 Cab with a burned out headlight bulb (HID style). The part number is Philips D2S 85123. These don't seem to be that common. However, the Philips D2S 85122 bulb is. The parts look similar. Can the more common 85122 bulb be used in lieu of the 85123?

Thanks

Peter

I do not think it is your blub, becuase HID blub, do not burn out.... its just gas inside.

check your regulator

Any D2S bulb of 35 Watts should work.

Easiest way is to just swap things from the working side to the failed side. HID bulbs can burn out, as the electrodes erode and stop liberating enough electrons or the repeated heating/cooling causes the gas to leech from the seals.

Thanks folks. I swapped the bulbs from side to side as suggested. The bad bulb stayed bad and the good bulb still lit. I appreciate the help.

Thanks again,

Peter

umm... yes they do. They eventually fail just like any other bulb tho they have about a 2000hr life span. Generally you know they are bad as they look dim and a different color. Buy a replacement bulb and it will fix the problem.

The ballast/ignitor can also go bad, but it's much more common for the bulb to fail than the ballast.

May I ask what bulb you finally selected as a replacement? did you use the Phillips 85122?

Thanks.

Hi,

I have a 2002 with litronic, mine both work, but i a want 6000k bulbs (yes i know they arent as bright). But i have now tried two different sets of D2S bulbs, both light up for a second, and then goes dark. If i put the stock bulbs back they work just fine. Any tips?

Ive fitted the same kind of 6000k bulb to other cars with no problems.

regards
