Ground

[Goonowsky]

Does anyone know where the ground is for the left headlight? Mines dim and i replaced the bulb and its still dim and i think it may e a defective ground. I dont wanna get pulled over for some crap like that... please help
thank you

i've currently got the exact problem as you...try wiggling the wires that connect to the back of the headlight bulb connector...this works for me, but the wires are getting very hot as if one is loose and arcing. hope this helps...let me know what you end up doing

time to replace the socket the bulb plugs into Im willing to bet if you take it out and look at it that it will be melted or the crimps on the wire have come lose.

yes, this is likely a bad connection at the wiring harness to bulb, if both lights were dim you could suspect something else

a visual inspection is your best bet, might be able to clean up the connection or do a little slight bending to get a tighter fit
