How to replace a BavGruppe Design eyebrow driver
Step by step: replacing a faulty BavGruppe Design eyebrow driver with the matched replacement we send you.
On this page
An eyebrow driver powers the LED eyebrow strip in BavGruppe Design custom headlights. If yours has been found faulty, this guide shows how to swap it for the matched replacement we send you.
What an eyebrow driver does
The driver sits inside the headlight, between the car's wiring and the eyebrow LED strip. It turns the car's supply into the steady current the LEDs need. Each driver is matched to its strip, so a driver from another kit may not work.
Before you start
- Only replace the driver once it's been confirmed faulty. Not sure? WhatsApp us photos first.
- Check you have the right replacement: 2-pin or 3-pin, matching the plug on your eyebrow strip (see the photos below). Some call the pins prongs.
- It takes a few minutes a headlight. No tools are needed, only access to the driver inside the headlight.
Steps
- Make sure the car and all its lights are switched off, and the angel eyes and eyebrows aren't lit.
- Find the driver inside the headlight.
- Check its wiring: one single yellow input wire and one braided input loom coming from the headlight, both on the same side of the driver, and one braided output loom going to the LED eyebrow strip on the opposite side.
- Check you have the correct replacement driver (2-pin or 3-pin).
- Disconnect the braided output loom (2 or 3 pins), and connect the braided output loom from the new driver.
- Disconnect the single yellow input wire (1 pin), and connect the single yellow input wire from the new driver.
- Disconnect the braided input loom (2 pins), and connect the braided input loom from the new driver.
- Check everything works before you reassemble or refit any caps.
- Tidy any spare wire with cable ties, so it can't snag or catch inside the headlight.

Common questions
Can I use any LED driver?
No. Drivers are matched to each eyebrow strip, so use the one we send for yours.
How do I tell a 2-pin driver from a 3-pin?
Count the pins in the plug on the loom that goes to the eyebrow strip. The photos above show both.
How long does it take?
A few minutes a headlight. You don't need any tools, only access to the driver inside the headlight.
Do I need to code the car afterwards?
No. The new driver works as soon as it's connected.
Is a faulty driver covered?
Yes, within a year. The replacement comes direct from BavGruppe Design, or from them to us and on to you.
The eyebrow still doesn't light. What now?
Check each plug is pushed fully home and no pins are bent, then WhatsApp us a photo.
