This website is offering H4 60/55 LED headlight bulbs. They are CE narked and so are road legal. I do not know if the heat sink will allow them to fit in a Classic Morgan headlight nacelle.

CE mark is a poisson rouge as it's a self certification scheme. I think LED lamps are in the same bracket as HIDs and thus only legal with a self levelling system.

I've also got my doubts than the beam pattern is anywhere near that of incandescent bulbs the reflector was designed for and thus will blind other motorists, squirrels up trees and anyone within range.

But I'd be happy to be proved wrong as the charging on my three wheeler is not very good, so reducing the power consumed is always handy.

These are a very nice substitution for the stock M3W lamps! Pricey but they use little power in comparison and the beam pattern is superb!

What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.

Which lighting regulation bundles LEDs and HIDs?

Can't answer that - I'm not redoing my research although I suspect the two are not really together.

However, you are going to have a problem with retro fitting LEDs, beam pattern. An incandescent bulb only lights up in a very small area whereas LED headlight bulbs have a larger area of illumination.

Don't get me wrong - I do want LEDs to succeed, but the combination of some sellers insisting they do pass inspection (which must be complete nonsense, the first ones I saw would fail an MOT even if Stevie Wonder was the inspector) and the rules not taking them into account properly either.

Interestingly those ones in the first post do seem to emulate the fixed point of the two filaments in the H4 lamp.

Not the usual cluster of LEDS

It may be worth investigating more....

If a bulb is CE marked, is the correct colour and is properly adjusted so that it doesn't dazzle, I cannot see how it could fail the MOT. As to whether they throw a decent pattern of light is another matter. As noted above the replacement H4 bulb looks exactly like the tungsten unit.

I am contacting TXTLighting regarding the pattern of light with the LED bulb in a reflector designed for a tungsten bulb. It may be you are right and it will be complete pants but the advances in LED bulbs, both automotive and domestic, are very rapid so its worth finding out.

I have contacted Honest John of The Daily Telegraph motoring section and he say he cannot recommend any LED bulb because of the risk of dazzle but his info may be out of date.

I will post again when I have more information.

When the beam is checked for an MOT pass, the second issue is basically covered, although not to the same extent as one might do oneself in the dark.

Certainly with rear bulb or indicator bulb sites, you'd be very unlucky to fail an MOT as the tester will not be able to inspect the bulb and as long as the light cast does not invite criticism it should pass

The CE mark is a self certification that the device meets European rules, and not the findings of an independent body. So the presence of a CE mark goes hand in hand with manufacturer.

I've set them an enquiry..

They are in China. So any quoted price will be plus import duty and 20% VAT

As a matter of interest the New Mercedes CLS has LED headlights, albeit with some clever gizmos so nobody get dazzled:
