Sounds like a bad ground on one side unless the ground wire inside the

Re: CJ Headlights - Passenger Bright, Drivers Dim?
 

Turned out to be a not just loose or bad - but completley missing -
ground wire. Broken off flush with the 3 prong socket tht the bulb
plugs into and thus was hard to see. Replaced the plug and now all is
well.

Thanks for everyone's input.
