This Headlight Booster harness is just the thing you need, if your headlights are dull and yellow, or if they are flickering (older cars have a circuit breaker in the switch when overloaded, it shuts off, then turns back on when cool). That is an indication that you are not getting the full 12v plus that your battery can give, by the time the power travels through your old, undersized wiring, through old switches and relays (if you are lucky enough to have them at all!) then back through your engine bay to your lights.

This kit has 4 sockets, for the outer & inner lights on quad headlight cars.

Super simple to fit, basically, 1 wire to the positive + terminal of the battery, unplug both of your headlights, and plug one of the cars plugs into the loom. Then the loom plugs into your headlights.

In a nutshell, what happens now is your car's existing wiring is just a switch, all the power is now traveling directly from the battery to the headlights.

Your existing headlights will now be much brighter than before if you weren't getting full power.

With a pair of 40 amp relays, you can now also safely fit higher wattage bulbs, without risk of shorting out, blowing switches or starting electrical fires.

NO GLOBES ARE PROVIDED WITH THIS RELAY KIT.
