I got this light for my R53 Cooper S and the plug in for the harness did not fit the harness in the car. I needed to modify the circuit board and change the wiring harness in my car so that it would fit.
I've been ordering from OutMotoring.com for years and have always experienced great customer support along with fast order processing.
I recently ordered some blackout rings for the tail lights on my F54 Clubman. Aaron and his team provided great service and support when I had an issue - organising a new set sent directly from the distributor to me in Australia. I have ordered from OutMotoring quite a few times over the years and this is the first quality issue I have ever experienced - having said that, with great customer service I have no hesitation in using them again.
