xenon light trouble
 

My left front xenon headlight on Boxster S 2003 keeps flicking off after a while. Any suggestions?

I would take a look at the connections first and make sure they are good...then if they look good take a multi-meter and check the voltage going to that side then compare it to the other side. If the voltage seems to be within range and not flucuating then your Xenon bulb may be shot.
