HID LOW BEAM HEADLIGHTS

2000 GMC Envoy

Electrical problem
2000 GMC Envoy 6 cyl Four Wheel Drive Automatic 135000 miles

The left side low beam headlight is out. I tried to take it out and put it in the right side, to see if it is the bulb or the system. But could not figure out how to get it out with out breaking the bulb. I have 2 questions: how do I get the bulb out and where can I get a new bulb or system. The bulb is one unit with the xenon light system. The bulb does not come out with out the whole unit coming out, including the sight system and the starter. The numbers for this unit are:
165261104
xenon light system # 928521028400
serial # 20886
bulb/starter # 16526491
I need to know if the kit that Xenon sells on line will work in my truck. Xenon has not answered my question about it, all they said was it works. I don't know if the kit is to upgrade to HID or to replace a unit.

Thank you

Thanks for your answer But that is not the right bulb. This is a xenon light system #928521028400 Bulb serial # 20886 bulb / starter #16526491. The whole headlight comes out the way you show it but the light bulb is different then the one you show. I need the right prints to look at.

Thanks again.

Hello – Ron…..sorry you are having problems with your vehicle.

Well, I have attached the directions for the bulb replacement and you can get them at Auto Zone or O’Reilly’s for sure.

Headlamp Replacement

CAUTION: Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:

Turn off the lamp switch and allow the bulb to cool before changing the bulb.
Leave the lamp switch OFF until the bulb change is complete.
Always wear eye protection when changing a halogen bulb.
Handle the bulb only by its base. Avoid touching the glass.
Keep dirt and moisture off the bulb.
Properly dispose of the used bulb.
Keep halogen bulbs out of the reach of children.
NOTE: Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode when the bulb is turned on. If either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and wipe the bulb dry.

Hello –

Thanks for the additional info…..however, the only thing I show is a Delphi system and Philips. Both are High Intensity Discharge (HID) which would refer to the xenon type. I also have those two for headlamp starter/arc tube replacement as well.

I will attach all 4 – Lord willing it is the one you need.

• Headlamp Replace - High Intensity Discharge (HID) (Delphi)

REMOVAL PROCEDURE

CAUTION:

The high Intensity discharge system produces high voltage and current. To reduce the risk of severe shocks and burns:
Never open the high intensity discharge system ballast or the arc tube assembly starter.
Never probe between the high intensity discharge system ballast output connector and the arc tube assembly.
The high intensity discharge system produces high voltage and current. In order to reduce the risk of severe shocks and burns, the battery negative cable must be disconnected any time service work is being performed on or around the high intensity discharge system.
NOTE: Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode when the bulb is turned on. If either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and wipe the bulb dry.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
