Headlight upgrade wiring harness. This loom runs from the battery directly to your headlights meaning your headlights will receive the correct full voltage of 12.4 volts and will be at their brightest. A lot of models are renowned for the headlights being dim and candles in the night as they don't receive the full voltage. The loom is completely plug and play and fits various models with H4 bulbs.
