I was out in my 2004 4.0L TJ yesterday and as it got dark I put my headlights on, which was fine,
if I put the my main full beam on there was a loud clicking from under the hood,
As I went back to normal headlights it stopped.
my first thought was the alternator, the battery gauge was showing 14volts.
I lifted the hood and put full main Beam lights on and it seemed the loud clicking was coming from the head lights.
Anyone got any thoughts or know what the problem is.
