5 x new replacement Red LED to replace blown LEDs on your auxiliary boot lid stop light for W211 E-Class models 2002-2007 which commonly fail after overheating or liquid ingress.
Soldering required. Save £££'s on buying a new light - repairing your original will be far better than replacing it with the poorly fitting Chinese import aftermarket models (I bought one and had to return when I owned an E-Class!)
