Hi Guy's,
Does anyone know how to replace the xenon low beam headlight bulb on a 2001 STS?

Thanks in advance,

Robert

Get a 10mm wrench and pop the hood. Take off the black plastic cover that runs across the front of the car(nice to have door/trim panel removal tool for this). There's two bolts holding the headlight in place. Remove them. Pull the whole light assembly straight forward(may take a little muscle). Take out the old bulb/igniter and replace with new one.

Not hard to do at all. My only suggestion is before you purchase a replacement bulb, take the other bulb(working one) and test it on the side that's out. If your good bulb doesn't work over there it may be a ballast. That's what mine was.
