1981-1988 GBody High Output Upgraded Head Light Wiring Kit Upgraded Headlights (4), kit and harness This kit will fit every GM car that takes this same size four headlight system, including all 1981-1988 A-Body and G-Body models. We have examined several of the various H4 headlight systems available and have found one that closely resembles the original style headlight. The headlight is glass and looks very close to the original glass face of your sealed beam headlight. To eliminate possible problems with the factory headlight switch and its ability to handle higher wattage bulbs, we also include a special plug-in harness. This plug-in harness takes the current directly from the battery after you turn on the headlights. The headlight switch is merely used to turn them on. This eliminates any possible problems with the 25-year-old headlight switch. The stock sealed beam headlights are 35 watts. These new H4 formatted headlights already have a 50 watt bulbs installed. The plug-in harness that comes with this kit has two 80 amp relays and an in-line fuse to prevent any overloads. The custom-made plug-in harness is highly recommended in the GBody cars to eliminate any possible issues with the original headlight switch. Issues with higher wattage bulbs can cause the headlights to flicker or turn offcompletely. This plug-in harness also allows you to upgrade to even higher wattage bulbs (maximum 80 watts). It has been tested running four 100 watt bulbs for over one hour with no problems. The plug-in harness is designed to be virtually undetectable under the hood. Just upgrading to the 50 watt H4 setup will be an improvement on overall lighting, compared to what now is the antique sealed beam format. Once you get this H4 upgrade, you can easily upgrade to higher wattage bulbs, if desired.
