Headlight Wiring Harness & Relay Kit – H4

Upgraded H4 headlight harness with ceramic sockets, relays and fuse — protects the switch and stabilises output. It is one of the parts Kenyan drivers replace most often, and the unit is built to the original mounting points and connector so it goes on without fabrication.

Key features

• Two relays and an inline fuse holder to take load off the factory switch.
• Ceramic bulb sockets that will not melt with high-output bulbs.
• Thicker copper cable than the original loom for a stable voltage.
• Plug-and-play into the existing H4 sockets.
• Includes ring terminals for a clean battery connection.

Fitment

Any H4-equipped vehicle, especially those upgraded to LED or high-output halogen bulbs.

Good to know

Fitting a relay kit before upgrading bulbs is what stops the headlight switch from burning out.
