This is a H4 / 9003 headlight relay harness with hi heat ceramic plugs for cars & trucks with 4 headlights - hi & low beams.

(plug and play harness!)

If your upgrading to halogen bulbs or you are having trouble with your 5-3/4" headlights not working properly - this is your fix! [100watt halogen bulb max]

This Harness Fixes:

  • Dim Headlights
  • Back Feeding Power
  • Flickering Headlights
  • Malfunctioning Headlights When Using Hi/Low Beams
  • Overloading The Headlight Switch
  • Overheating Plugs

This is a h4/9003 12v headlight conversion wiring harness with hi heat ceramic plugs for cars that have upgraded halogen or xenon h4 bulbs. The stock headlight switch cannot handle the necessary power needed to light the halogen bulbs so the headlights will eventually overload the headlight switch and end up making the lights dim, flicker, or turn off. This harness bypasses the power draw from the headlight switch and pulls the power directly from the cars battery, but still uses the stock headlight switch to activate the relays to turn the headlights on and off. The ceramic plugs wont melt like standard plastic plugs will from the higher heat that halogen bulbs put out. This is harness is a direct plug and plug with all the correct factory style plugs for the high and low beam headlights! [ Harness can not be used with bulbs higher than 100watt halogen bulbs. ]
