Wiring the DRL harness
One of the key features of our headlights is to have the ability to run the DRL strips in the day without having to activate any of your lighting controls manually. The way to do this is by wiring the harness that is included with your headlights.
Depending on the headlights feature you get, there will be two types of DRL harness. One that comes with a yellow wire and one that’s without the yellow wire. If your DRL harness did not comes with any yellow wire , just leave the connection on the headlight unplug . For DRL harness that comes with a yellow wire , connect that to the nearest headlight, you will only need to connect to one headlight and leave the yellow connector on the other headlight unplug.

The function of the DRL harness is to allow the DRL with different intensity during daytime and night time. Basically, the DRL harness will supply extra power to the DRL for brighter output during daytime, and when the parking light is on, the DRL will be at reduced intensity. With the optional harness installed, the headlights will function as follows with most vehicles:
Ignition/Engine ON | – DRL at High intensity |
Parking Light ON | – DRL at reduced intensity – amber side marker |
Low Beam ON | – DRL at reduced Intensity – Amber side marker – Low beam on |
High Beam ON | – DRL at reduced Intensity – Amber side marker – Low beam on – High beam on |
Automatic Function | – Will function as normal |
Tapping the grey wire to the ignition
With the grey wire, you will need to tap it into a switched fuse under the hood. We recommend that you use a fuse tap similar to the picture below.
