Description Reviews This MINI Tail Light Bulb Socket will fix the bulb out code for the rear tail lights that is not just a bulb. We see it a lot in R56 Cooper and Cooper S's and normally on the right side, but the left is not immune to it. What happens is the board overheats and the top bulb socket loses contact. Through testing at Detroit Tuned, we have tried to repair and wire brush the unit to make the connection it needs; but it needs to be replaced to get fixed correctly. Luckily the part is not too expensive and even the most shade tree mechanic can do this job. Fits: MINI R56 (10/2005 — 08/2010) MINI Cabrio R57 (10/2007 — 07/2010)
