Description

LED Headlight Relay Harness Kit with H4 Negative Switched Plug for Bulb Wiring

Flickering headlights Malfunctioning headlights when using high/low beams Overloading the headlight switch Overheating connectors This is an H4/9003 12V headlight relay wiring harness with high-heat resistance Ceramic connectors for vehicles with upgraded halogen or HID H4 bulbs H4 dual-headlight relay harness for H4 bulb conversions The factory headlight switch cannot handle the increased power demand of high-wattage halogen bulbs, which may cause dimming, flickering, or failure. This harness bypasses the headlight switch for power delivery—drawing current directly from the vehicle’s battery—while still using the original switch to trigger the relays for on/off control. The ceramic connectors resist melting, unlike standard plastic connectors, and are designed to withstand the higher operating temperatures of halogen bulbs. This harness features direct plug-and-play installation with OEM-style connectors for both high-beam and low-beam circuits. Voltage: 12V Power rating: 60W Compatible with 12V H4 bulbs Color: Black Material: ABS Package includes: 1 x H4 Relay Wiring Harness Kit
