Ok, im sure this has been explained elsewhere, but, my passenger side low beam went out. I am not sure which K bulb I need for the HID. It says the most common is 6000 but I wasnt sure. I want to make sure it matches my driver side and that is stock. But what should I be looking for? DE2? How much? I've heard I may have to take off the front bumper and all this nonsense. If anyone can help, thanks, I got a 2001 S2K.

 

You must remove the bumper if you are taking out the headlight. otherwise, just remove the fender liner to access the back side the the light. The lightbulb is a Philips D2S 35w

 

What he said.

I know when i turn my lights on, one would sometimes not turn on. At first i figured it was blown, might sound weird, but i turned them off by accident (signaling) and they both turned on normally when i switched them back on. This happens to me every soo often.
Wouldn't hurt to see if your "burned out" one turns back on when you switch between on and off a few times.
