It looks like with MOT rules changes from 1st January 2021 all of us with LED headlight bulbs will have to remove them to pass this year’s MOT. It’s a real shame as it’s one of the best upgrades I have installed on the Jazz.
I can’t see the problem if the beam pattern is correct The cut off on the Classic Car LED H4’s is so much better than halogen bulbs.

My Civic passed its MOT in late January with the LED bulbs still fitted....
Presumably your MOT tester didn’t know about the revised rules or chose to ignore them.
My regular tester who is a friend has retired so I will have to find a new tester this year, so I may not be as lucky as you.

The boy racers used to regularly change their bulbs from HID to filament for MOT, any MOT tester worth his salt knew that - for one day out of 365 the original filament went back in. It is not big job to change back to filament, as the 3 pin socket is still there, just unplug from constant current LED power supply and plug onto back of normal bulb. Wouldn't want to do it on a MK1 though, but on Civic and MK2 and later Jazz the bulb is easily accessible... I will leave LED in wifes Jazz in July and see what the tester says, get a free retest anyway. My MOT place is pretty much on the ball as they do loads of MOT tests, they have 6 MOT bays - the reason I chose them is 1. they do motorbikes and 2. they are not a garage that fixes vehicles, so no vested interest in failing a vehicle just as a work-creation scheme. They do performance tuning and customise high power cars, they used to do Ford Cosworth customised vehicles ( including Transit vans
) now they concentrate on Nissan Skyline etc.
To me the important thing is the beam shape, and as others have remarked the cut-off and nearside spread of the Classiccarled LED is much better than the best filament bulb it ever tried ( and I tried most of them ), and the only one that came close on beam shape was the Philips ones.
I am guessing that there have been an increase in MOT failures in past few years for bad beam patterns and this has been put in to cover that ( as if the current beam pattern, light colour and brightness regulations were not enough ) - as I said inspector has never mentioned beam pattern on either of out cars.
