Headlight wire harnesses

A headlight wire harness upgrade is the most effective element you can use for your truck’s headlights. Stock wiring is bare minimum and generally results in low voltage, which reduces the light output of headlight bulbs.

Paradoxically, if you install higher-wattage bulbs before upgrading the headlight wire harness, the OEM harness and plugs could melt under the excessive current draw.

Using an upgraded plug-in headlight wire harness will improve current delivery. Power is then drawn directly from the battery using wiring that is thicker than stock, and then delivering that to the headlight bulbs.
