I won’t be making these myself, but I’ll share the instructions here. The most challenging part was designing the PCB, which I’ve already completed through a lot of trial and error. I’ll upload the PCB files so you guys can get them printed at JLCPCB.com—this is the service I used. Once you have the control board, all you need to do is create four pigtail harnesses (two for each side) and place the board in a waterproof/weatherproof enclosure. I’ll also look up the part numbers for the connectors and pins.
The installation is simple: unplug the harness from the headlight housing, connect it to one side of the PCB, and then plug the pigtail from the other side of the PCB into the headlight.
If you’d like the option to switch between amber and white DRLs, you can run two wires from the PCB into the cab and install a two-position switch.
Alternatively, if you don’t want to run wires into the cab, you can place a small jumper on the PCB itself, allowing you to have either white or amber LEDs. (Can't switch colors on the go)
I’ll try to make time for a more detailed write-up with pictures. I’ll need to sift through some old emails since it’s been a while.
The lights have been working great and look fantastic. I haven’t had any issues with them. As a courtesy to other drivers, I switch to the white DRLs at night because they automatically dim with the light sensor, while the amber ones are super bright.
really want Amber DRLs
