HEADLIGHT REPLACEMENT

2003 GMC Envoy • 6 cylinder 4WD Automatic • 127,000 miles

I have a 2003 GMC Envoy and the right headlight burned out. When I replaced the bulb it only worked infrequently ( I used replacement bulb 9006). Upon closer examination I noticed the clip on the bulb was brown/black. Could the wrong bulb cause this? Could the clip burn out over time? Can I replace the clip only or do I have to replace the whole headlight assembly?

If the problem is the electrical connector, yes, you can replace the connector? When the problem is ongoing, did you check for voltage and ground at the connector. If you wiggle the connector, does it make any difference?

When I wiggled one of the wires on the connecter it would cause the light to go on or off. The headlight had remained on until this happened.
