Usually, when one headlight is dimmer than the others, it is a loss of ground that is the culprit. Check for loose or corroded connections. If all else fails, a new ground wire can be run from the effected lamp to a grounding source (frame/engine). I've had this problem for years. If you find a solution please let me know. I've ripped up the wiring from just beneath the driver headlamp all the way to the other lamp. I've found tons of rotted connections, fixed them, but never the original problem. Still looking!
check your fuse for that headlight even if it is blown it will still get power because of the way the circuit is set up it is called a sneak circuit . power backfeeds through the lights causing this condition.
