    Hi, the other day my vehicles headlight was not working which are fitted with gas discharge headlights all I could check was the power supply and earths to the module as the high voltage to the xenon unit could of gave me a "belt" or seriously burnt me.

    As it was the bulb was faulty, is there any way I can test a xenon bulb I took an educated guess and lookily was right there really expensive for what they are.

    A test with an ohmeter perhaps?

    What sort of voltage am I looking at is it high current or low?

    You might have to get the part number and search on that to get correct information.

    Xenon gas tubes take a high current through them to produce the light. The gas gets ionized by an application of a high voltage pulse. Your headlamps may operate a bit differently.
