Potential Dashboard Warnings: When upgrading to projector headlights with DTRL signals and possibly adding LED/HD bulbs, you may encounter a light - out message on the dash, lights not working, lights shutting off, or hyper - flash. Solutions for Warnings: We recommend using alfaobd to enable LED lights and turn off error messages. Alternatively, you can add inline diodes or CAN - BUS eliminators, although the latter may not fully resolve the issue of lights turning off. If you have any questions, feel free to message us.
