dim headlight on 99 ram

my 99 ram has a dim headlight on the drivers side only even after changing the bulb passenger side is fine any ideas? thank you

you have a bad chassis ground on the headlight look for a pig tail ground wire from the headlight to the chassis i bet it broke or is corroded/bad connection. Usuall the wire will have a lug on it and screwed to the radiator support or some part of the chassis ground. Good luck.

i cut behind the light socket into the ground wire and grounded it and it worked but now head lights stay on all the time any help. thank you

might of gotten the wrong wire to ground. Should be a wire going to the ground by a pig tail with a lug like i said Try to look real good FOR THE WIRES TO THE CHASSIS. The wire you grounded might be from relay that controls that headlight a wire befor the relay. Try to get awiring schematic for the headlight wiring and you should see the ground wires fir the headlight wiring. I had a problem yrs ago on my 1969 GTO that only one head light lit dim had to remove the bumper to get to the groung wire and low and behold a corroded lug from the one headlight that was bad.
Well good luck and look good and hard for that wire.
