I am having problems with my bright lights going out after about 5 min.s, they will burn all night long on dim. do you think its the dimmer over heating? 1994 jeep cherokee 320,000 miles thanks in advance!

Is your 1994 not a sealed headlight with two different lights inside of it? My 1992 has a switch on the dash that pulls toward the hatch like a piston. That powered the headlights at +12v to the low beams. The multifunction switch on the column being pulled toward the hatch switches the power to the high beams. It, also, illuminates the bright light indicator in the dash. Is that how yours functions?

Did you ever solve this issue?

HEADLIGHT HARNESS UPGRADE

NOVEMBER 17, 2015 SALAD 48 COMMENTS EDIT


It’s easy to install a supplemental headlight harness.

From the factory, the voltage to the headlight bulbs travels from the battery, through connectors, inside the cabin, to the headlamp switch, and then back out to the lamps via undersized wire and more connectors. It’s not uncommon to find only 10.5 volts at the lamps.

The supplemental harness is installed so that it provides battery voltage to the lamps and is just triggered by the factory wiring. The result is about 35% brighter headlamps and headlight switches that don’t melt and burn out.

Here’s a link to a harness on ebay: http://www.ebay.com/itm/CERAMIC-H4-H...-/330997592807

Absolutely plug and play:

• Remove grille and headlamp bulbs. I fed my harnesses from the passenger side starting between the battery and the back of the headlamp housing, over to the driver side.
• Plug the driver side bulb into the new harness.
• Attach the new harness’s ground wire under one of the small bolts on the radiator support after scraping the paint off under it.
• Attach the harness to the existing harness behind the grille working toward the passenger side.
• Plug the new harness plug into passenger headlamp.
• Plug original headlamp plug into receptacle on new harness.
• Attach the ground for the passenger side just like you did the driver side under a radiator support bolt.
• Attach relays with provided bracket on the passenger side inner fender.
• Connect power wires to battery.
