1999 Toyota Corolla Harnesses at Tuners Depot

These Nokya Heavy Duty Headlight High/Low Beam H4 Wire Harnesses have been designed to be plugged into your Toyota Corolla's stock wiring. Aftermarket bulbs or not, your Toyota Corolla stock lighting H4 harnesses are not designed to handle extended periods of use, or operation in adverse or severe conditions. To address this, Nokya offers these H4 Heavy Duty Headlight High/Low Beam harnesses as a cheap and relatively easy upgrade to your stock Toyota Corolla electrical system. They work as replacements for damaged stock H4 harness plugs, or as complete upgrades as a precautionary measure against harness plug burnouts (which can permanently damage your Toyota Corolla headlight housings). These Toyota Corolla Heavy Duty Headlight High/Low Beam H4 Wire Harnesses also help to handle the increased demands of aftermarket Headlight High/Low Beam bulbs, Nokya brand or otherwise. Each set consists of 2 harnesses.
