    so i noticed that my passenger headlight will sometimes be out, my fix is i go and tap on the headlight assembly and it will come on.. every once in awhile it will be out again...any ideas why it is doing this? thanks in advance

    Yep it's the bulb. Most likely the element is broke and when you tap on the assembly the element makes contact.

    Just fixed this same problem on my son-in-laws car last weekend, bad element in the headlight.

    I would have to agree with the previous posts that the best place to start would be to change the bulb. If you find that this does not solve the issue, please feel free to contact me directly. Thank you.

    Same thing happened with my truck, ended up the connector was damaged.. the "prong" (for a lack of better words) had become stretched out.. I took a small screwdriver and pried them back together and haven't had any problems since..
