I checked their "bulb finder" app instore and purchased the appropriate LED bulbs for the reversing lights on my Mini. I also asked them to install them for me. For whatever reason, it turned out that the bulbs I had purchased were not suitable for the reversing lights. However, the Fitter was kind enough to find the correct bulb and to fit that for me. He was able to install the other set of bulbs as LED replacements for my rear indicators which was great. The Fitter was knowledgeable, efficient and very helpful. Will definitely use the fitting service again.
