Still rocking the stock white angel eyes on your M3 or M4?

• Every M4 CSL on Instagram has those aggressive yellow angel eyes and your standard M3 just looks... tame in comparison?
• You looked into the CSL headlight swap and found out it costs $8,000+ for the full assembly?
• You want that DTM / CSL look without ripping apart your front end or paying a shop hundreds for coding?
• You tried aftermarket LED strips and they looked cheap and uneven — nothing like the factory CSL?

Specifications

Compatibility

Important: You must select the correct version (LED or Laser) for your headlight type. Check if your headlights have the laser option — laser-equipped headlights have a blue accent line inside the headlight housing.

Frequently Asked Questions

How do I know if I have LED or laser headlights?

Laser headlights have a small blue "X" or blue accent line visible inside the headlight housing. If you do not see any blue markings, you have standard LED headlights. You can also check your vehicle order (VO) for option code S5AZ (Laser Light).

Will this cause any dashboard warning lights?

No. The modules match the factory electrical specifications exactly, so the car does not detect any change. No error codes, no warnings.

Can I switch back to white?

Yes. The original white modules can be reinstalled at any time. The swap takes about 30 minutes once you know the process.

Does the RGB version work while driving?

The RGB controller allows color changes while stationary. For road use, set it to a static yellow or white color. Flashing/strobing modes are for show use only — check your local regulations on DRL colors.
