Windows tinted WOOHOO and LED sidelight bulbs changed for better ones

Just don't be tempted with the "ice white" LED s. Mine passed three MOT tests with those at Audi, then failed at the local Indy. Not impressed!

What was there reason for failing with the white LED's

Only reason I asked is my motor was tested last week at my garage and just by luck in the afternoon we had a VOSA spot inspection check where they pick a car that has been tested and re test it to check on the MOT tester to see if he has done his job correctly, mine was the only car on site that had been tested that day so he used mine to re test and the VOSA inspector said nothing about my white LED side lights and gave my car the all clear, so if he passes them the garage should definitely not have failed them????
