Hi. I’ve used these Osram W21W’s in my H7s. Work a treat and I get no bulb out messages.

it is only an MOT failure for very new models. Mine is 16 plate and has gone 3 times this year ... so I have given up at this stage. BUT NOT an MOT failure for me. not exactly sure when they changed possibly 2018 - but plese check on.Gov MOT site.Is this a common problem? I've one DRL out and Mot in 1 week. I checked the bulb and it looks good but the holder is melted. I guess I'll have to remove the whole light to see if it's fixable.
