What, you are supposed to use them? Now I know where I have been going wrong
Seriously though, as long as the MOT tester is happy with the brightness then they are fine to use...I have to say that since I sold them to Chadmat
I have clear indicators fitted and clear repeaters and have just yesterday swapped the orange bulbs (on the main idicators) for the silvered ones that blink orange when used, just as bright as before and I have lost the fried egg appearance, great for a fiver

. I actually didn't want clear indicators but after finding a crack in one which meant it filled with water when raining it was cheaper to get the aftermarket ones than buy from Fords, I know ebay exists but they (stock orange lens) are basically Ford prices anyway and with 'used' you really don't know if you are getting a 'good' pair.
