So I was on my way home tonight from Import Alliance Baltimore, and I was driving down the interstate and noticed in a reflection of another car that my driver side headlight was out. Odd enough I turned off the headlights and turn them back on and both headlight came back on. I thought it was fine, then when I drove for about another 5 minutes the driver side cut off again! Not sure if I'm having a bulb issue or the ballast is going bad, or even maybe the wiring? Haven't had time to check just yet, Any Ideas?!?!?!

Thanks in advance!

 

Start with the basics and check the bulb and make sure the connector is plugged in properly. Is the side thats acting up a slightly different hue then the other side? Also you can try lightly hitting the headlight with while its turned on to see if it turns on and off in which case its probably a bulb. Once those check out you could start looking at ballasts and wiring.

 

When the driver side bulb is out is the driver side high beam out as well? If so, headlight relay 2 underhood may be going out. If not, most likely a poor ground, or connection at the bulb.
