I have just received in the mail the LED rear licence lamps, thanks to another thread confirming they will work, error free.
2 License Plate LED Kit No Error Mercedes W211 S211 E Class W219 CLS R171 SLK 55 | eBay
Can anyone confirm after installing, other LED lighting options that are error free (no bulb out indicator) for the eyebrow lamps and side markers? I'm looking for LED lamps that can simply plug into existing sockets. TIA
