Compatible with 2014 2015 2016 2017 Pre-LCI F32/F33/F82 4 Series
Powered by 13-SMD brilliant red LED for an unparalleled 360-degree illumination
Great as an upgrade for the stock brake lights (replace the smaller H21W bulb not the larger 7506 bulb)
Special note: when you remove the base of the tail lamp, there are two OEM bulbs, these H21W replacement bulbs are meant to replace the smaller brake lamp bulbs, not the bigger turn signal lamp bulbs
