Thread: Defender Headlight Wiring

Hey mate.. I made a video exactly on this...
[ame=http://www.youtube.com/watch?v=TKr9t56tJxg]Land Rover Defender Headlight Relay Upgrade - YouTube[/ame]

I ran a 25amp fused cable directly from the battery to 2 relays in the engine bay. From there you can run heavy enough cable to power your higher wattage globes. There is no need to modify the existing harness... just wire in the new wires for the relay/headlights and plug in to your existing harness.

DIY kits are available as well from drivesafe, one of the members on here.

I used this one when I did mine as I did the driving lights and the headlights at the same time and also used the genuine LR switch.

Brett thanx for the link. I have followed you advice on the LED dashboard upgrade with much success. When you say plug into the existing harness does that mean linking the dim and bright cables on the light harness to the relay itself to "toggle" between dim and bright.

Basically you have a male h4 plug from the relays which has one wire connected to the low beam relay, and the other to the high beam relay. This plugs in to either of your original h4 female headlight plugs to provide a low current 12v feed to power the relays. No need to modify any other wiring. :-)

Hi Theo and if you follow the link at the bottom, it will take you to two Defender specific kit in the Verandah section.

Here are two diagrams from these kits.

Brett correct me if I'm wrong. You will actually fit new plugs to the headlights which provides new power with thick cables from the relay. Power directly from the battery to the relay and then you use the existing headlight plug and link that to the relay to allow for dim and bright.

Thanx

That's correct.

As you see in my video the relays have their own H4 female connectors (with thicker wire) to connect to the headlights, and the relay has a H4 male connector which plugs into the original female headlight loom to control dim and bright.

If you're thinking of doing it yourself my vid has a list at the end of what you'll need, otherwise pm drivesafe for his kit... it costs about the same as making it yourself...

Brett

Thanks for that Brett and I like your video, nothing better than seeing how to do it before you start.

I noticed a few other videos on there with yours.

If you have the time, PLEASE make one on how to solder cable into Anderson terminals. That prat with the Anderson plug video actually describes how to destroy a solder joint. And considering it’s for high current use, thats a dangerous bit of instruction he gives.
