IF YOU’RE UPGRADING TO HALOGEN BULBS OR YOU ARE HAVING TROUBLE WITH YOUR 5-3/4″ HEADLIGHTS NOT WORKING PROPERLY – THIS IS YOUR FIX! [100-watt Halogen Bulb Max]

This harness is known to fix:

• DIM HEADLIGHTS 
• BACK FEEDING POWER
• FLICKERING HEADLIGHTS
• MALFUNCTIONING HEADLIGHTS WHEN USING HI/LOW BEAMS
• OVERLOADING THE HEADLIGHT SWITCH
•  OVERHEATING PLUGS

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.
