Re: CJ Headlights - Passenger Bright, Drivers Dim?
Swap the bulbs first of course. Then dig out an ANALOG multimeter, much
better at finding intermittant problems and diagnostic work.
The easy way is to turn on the headlights, see the dim bulb. Check the
voltage to a good ground (battery terminal if possible) on BOTH sides of
the bulb with the lights on. A good system will read 12 volts or a bit
less on one side, 0 volts or a bit more on the ground side, 10 to 11
volts across the terminals. If you get less than 10 volts on the high
side, start looking for a bad terminal block or frayed wire. If you get
several votlts on the low side, bad ground. The bad ground can either be
on the wire from the socket to the body or the ground strap from the
body (on the firewall) to the back of the engine

Re: CJ Headlights - Passenger Bright, Drivers Dim?
Assuming the lamp itself is good it appears that you have a circuit
grounding problem.
You will need to get in there and manually clean (and coat with dielectric
grease) the ground connectors and connections. Perhaps another Jeeper can
give a specific locations to check, I'll just say take apart and clean every
connection you can find.
FWIW.... I had a '68 Rambler American with the same problem which occurred
at some very inopportune time so I temporarily added an additional ground to
the circuit by tinning both ends of a section of 14g house wiring and using
it as a jumper from the ground side of the dim headlight to a bolt on the
grill. I drove that Rambler for a number of years before giving it to my
baby sister who drove it until 1986...... with that temporary fix still
doing its job! (Not that I recommend you do this bit of hillbilly
re-engineering)

Re: CJ Headlights - Passenger Bright, Drivers Dim?
The ground tags for the headlights are on the back of the grill. I
would be thinking one of these wires got damaged or is loose.
Or a loose plug on the back of the light...
