Hi,
I have a 2024 Lexus NX350h (EU model) with standard LED headlights (not adaptive). I need to know which wires control the low beam, high beam, and DRL, as I want to connect an extra LED bar to the high beams.

Does anyone have a wiring diagram or know the wire colors/pin functions?

Thanks!

 

Don't tap the headlight wires directly. It can cause errors and damage. The proper way is to use a relay. Tap a signal from the high beam wire to trigger the relay, then run a new fused power line from the battery to the light bar through the relay. You'll need a wiring kit. Check the fuse box for an empty slot that only gets power with the high beams; that's an even cleaner way to do it.

 

It will be used with a smart relay. I just need to know which wire is responsible for the high beams.

 

ok I don't down my self
