I can't see those producing a tightly controlled beam pattern, as the emitter is too large for the reflector. The reflectors in headlamps are designed to focus and project light from a tiny point the size of a filament. If the LED emitter is larger than the original filament, then the light will be produced will be outside the focal ability of the reflector, so won't be controlled correctly.

The most accurate LED replacements use tiny emitters, but these will also technically fail the MOT.

Not 100% the case.

A filament will project light in all directions. An LED doesn’t. The physical size of the LED is largely irrelevant in this context. The reflector or lenses will still focus the light. And in a headlight you don’t want tightly focused light as it isn’t a spot light with a central hot spot.

Just use some 150% brighter Osram Nightbreakers... They dont last as long as standard bulbs, but make a huge difference, and will pass an mot.

And you can blind people. Especially the old peeps and themselves with cataracts.

They shouldn't be able to see just because you can.

Thank you all,

It's a certified no! Lol I shall look for some slightly brighter halogen bulbs as the better option.

Phillips Racing Vision 200 or Osram Nightbreaker Laser 200.

Are you for real.... ?

Don't buy them from Hal-frauds either, they will cost you twice the price. Eurocarparts were reasonable when I bought mine. Even against General Traffic, who I have a trade account with.
