They do, just make sure the ones you get are CANBUS enabled so you don't get bulb warnings. Also make sure they are not too long, mine are 36 mm and you'd be struggling with anything much longer.
I've had LEDs for 2 MoTs and passed without a problem despite them being quite blue. I'm in the process of replacing them with white LEDs, but have problems with the lamp part rotating on the base and they are loose in the holder so I wouldn't recommend the ones I bought off the bay, despite them being very bright. Have secured the lamps with epoxy resin and will make another attempt to get them working today.
For reference these are the ones I got - but BEWARE of the problems I mentioned
