Description Reviews This MINI Tail Light Bulb Socket Kit will fix this common bulb out issue with ease. If you routinely get a bulb out code for your rear taillight, and a bulb replacement is not correcting the issue, more than likely your MINI taillight has a melted component on the circuit board. We see this as a frequent issue in the Gen 3 models. This new board and wire harness is needed to make the taillight function properly. Kits includes: MINI Tail Light Bulb Socket #63-21-9-477-857 Repair Socket Pigtail Kit #61-11-8-795-459 Fits: MINI F60 (11/2017 — present)
