    My 2012 JK Wrangler right head light will not come on sometimes If I pound on Lense with my hand, it will come on and be ok for a while. I put new bulbs and cleaned and put Dielectric Grease on plug. I am thinking thing poor ground. The center wire is the ground may be splice and add on wire to it for a better ground. Any other Ideas ??

    Banging on a fixed position headlight to get it to turn on is usually the bulb or connector both of which you appear to have addressed. Use a multimeter with the headlight removed testing each prong on the connector for signs of intermittent power while moving the wires, connector and further down the wire harness. Too much dielectric grease can sometimes cause issues too. Swap the headlights R>L

    Yes....I'm commenting on this one. Lol.

    If you have to bang on ANYTHING to make it work. Replace it. You'll be happy you upgraded.
    As @aggrex suggested.
    Check connections, grounds and any other connections that might affect its proper operation. And only apply a thin coat dielectric grease. Electrical gremlins can suck....big time. Start with the basics....:annoyed:
