LEDs with Halo DRL

Connection Guide

Congrats on your purchase of 9HAUS LED Headlights! Connecting the Hi/Low Beams of your LEDs is exactly the same as all other headlights, just plug in the H4 plug to your car, or use the H5 adapters if your car has H5 plugs.

Connecting the Halo is also very straightforward. We provide separate wiring for Halo DRL so that you can connect them in any way to achieve the look and functionality you like.

The 2 wires that come out next to the H4 plug are:

Red: (+) for White Halo

Green: (+) for Amber halo

Ground is shared with the H4 plug, so no ground connection is necessary.

Most of our customers prefer to connect the White Halo to parking lights, so that DRL's can be turned on without turning on the headlights. The parking lights wires in the headlight bucket vary from model to model. The best approach is to identify the parking lights (+) and connect it to the Red wire. You can identify the wires by measuring the voltages with a multimeter. Amber DRL's can be connected to turn signals in the same way.

If you don't have parking lights wires in the headlight bucket, you can run a wire from the light housing below. Some of our customers prefer to install a separate switch and fuse. It's also possible splice directly into the headlight plugs, so that the DRL's turn on together with the headlights.
