Unfortunately for me the LED bulb comparator didn't work and again unfortunately blew a fuse or fuses we are yet to find out as it is booked in with the main dealer,but that's another story., so it was not the easy direct replacement I hoped it would be. Why still 4 stars? Well unfortunately things can go wrong ,but I always think it's how a company responds. I mailed them,they apologized ,offered to exchange them,I declined and so they mailed me the necessary returns info' and on receipt credited my account. Yes I still have my wife's car with no DRL and sidelight and it will cost but I was happy that when something goes wrong they didn't make it more difficult. Would I purchase again, yes because I know their returns policy works should I have to use it. Put me off changing to LEDs though !
