These are what the LEDs from ClassicCarLEDs look like by the way


I tried some of those less in my mini about 3 years ago, Philip's ZES chips positioned to replicate the position of the H4 filaments- they were very good and gave a very clean beam image cutoff. Mine were typical LED cool white, don't think warm white was an option back then.
I refitted my equally illegal 100/140 watt halogens as I didn't like the cool white colour in a classic car and while the leds were very good they just couldn't match the massive light output of the 100/140 watt halogens.

As of 1 January 2021, section 4.1.4 of the MOT Inspection manual reads: “Existing halogen headlamp units should not be converted to be used with high intensity discharge (HID) or light emitting diode (LED) bulbs. If such a conversion has been done, you must fail the headlamp.”

-from the Daily Telegraph 27th January

Oh brilliant! I’ve just this week finished fitting the Classic LEDs to an MGC and it wasn’t just a replace the bulb process - the beam pattern is far superior to the halogens they replaced but clearly that doesn’t matter a jot! I was going to do the Mini next. At least the MOT isn’t due until October :wacko:

Let’s be honest, MOT testers don’t look at the type of bulb, just the beam pattern. so I would presume a good quality LED bulb, like the ones classic car LEDS sell, would probably pass no issue.

So as you are about to drive your freshly MOT car off the ramps a Ministry inspector arrives and asks to see a car that has just been tested>>>yours(apparently they can and do this).It is the testers license and livelyhood,some items are subjective and some are clear.Just a thought.Steve..PS they analyse the data of all tests for every tester and could possibly run a program to list all testers who have never failed an LED conversion perhaps?Steve..

As I said, if the car has the correct beam pattern and traditional light colour, they are hardly going to pull the bulbs for the sake of it, they will more concerned flagging more common Mini fail points that might get missed. Your scenario is of course possible, but highly unlikely.

I can see some validity in that argument. If the tester can't tell they're LEDs by doing what they're allowed to do during the test they can't reasonably be blamed. Like fitting a full body kit over rotten sills.

 

Can't help wondering though: if an MoT tester can't tell they're not halogens, what's the point in fitting them instead of halogens  :P

 

Personally, I'd ban all headlights that have a brighter dip beam than 55w Halogen. They're more than adequate for illuminating as far you need to see.

 

Dip beam is supposedly specified to illuminate 50m: the stopping distance at 50mph.

 

Every headlight is capable of dazzling other road users in certain conditions, we don't drive on billiard tables.

This ^^^

I have never seen a reason to want anything brighter than a standard wipac halogen upgrade.

Which is why cars fitted with LED and HID have a self levelling system. So as to compensate for load and road conditions. 
 

can’t say what they always work correctly.

Does the ban also include those god awful halo things?

To be fair, I can only applaud this. Being blinded by LED’s is a big nuisance.

There's not much point in levelling the headlights when you can't level the road in front of them. It's a logic defying mystery how the problem could be acknowledged by imposing a solution that obviously wouldn't work  :wacko:

I've just finished fitting Land Rover Defender LED units to my Mini. I'm assuming I can get away with keeping these, as it specifically says "existing halogen headlamp units should not be converted..." but no mention of fitting new LED headlamp units altogether? It's just the halogen conversions that are now illegal?

I don't think it's a problem if you've fitted a complete LED headlamp unit, its LED's fitted into headlamp units designed for H4s that are the problem.

Can you tell us which units you have fitted?

 

Do you mind saying where you purchased them?

In the article it mentioned the cost of LED headlights sold as a unit.

 

My daily driver is a DS3 and has these fitted, nearly a grand each side to replace.

 

I'm hoping someone will start a 'cottage industry' replacing the failed LED elements in these types of headlights and selling them a lot cheaper.
