LED 'H4' replacement units are illegal and will fail an MOT. Invest in some decent H4 halogen bulbs and upgrade the headlamp wiring harness (a couple of options available commercially) so the bulbs get full battery voltage and the lights will be great.
Just one example of a headlamp wiring loom upgrade here - https://www.paddockspares.com/boomslang-pe...-loom.html Not the one I've got so can't comment on it either way, but you get the idea. 100watt H4 bulbs would most likely melt the lens of the Crystal lights as they generate a tremendous amount of heat. Polycarbonate is tough but it will melt. |

Decent LED bulbs such as those supplied by Classic Car LED's are excellent but as Penfold says, are now illegal in the UK. You'd have to check your local rules before committing to them. Darren

And only illegal in post 1986 vehicles in the UK 😉

Having run with LED conversion "bulbs" in Wipac crystals for a time, I can assure the OP that they produce a cleaner, brighter, more sharply defined, and generally superior light pattern than any halogen bulb. They will also, with no problem, pass a UK MOT test beam alignment check and will not cause inconvenience to other road users (which is more than can be said for modern adaptive beam and matrix lamps, which presumably but inexplicably are legal).
In the UK the illegality is purely due to to type approval reasons and not due to function (and is arguably and affront to common sense), but the sad fact remains that they are technically illegal on post-'86 vehicles. I replaced my "crystal plus LED bulb" with top-quality, type approved LED units, which produce a significantly inferior main beam but are broadly comparable on dip. If it is legal for you to go LED, or if you are prepared to take the risk if it isn't, then go (quality) LED. The light output is better is every respect. |

+1 ^^^
I have the classic car type LED bulbs in my 110, and as BW says, the beam is soooo much crisper and sharper. It's also passed an MoT with no advisories regarding brightness/aim etc. I know that "just because it passed an MoT doesn't make it legal", or "because a copper didn't pull me over blah blah", but wanted to pass my 2p's worth on. |

DO those "Classic Car LED's " get too hot for the rubber cap? Puma 110" SW

What ones did you fit? I went back to Crystals and miss my Tuck Lites but couldn't bear the though of smashing a £600+ set of head lights on the farm. The horse had nearly nutted one of the Truck Lites in the yard... |

Funny thing those bulbs do not fit into my crystal headlights (LHD) . Bulb´s diameter is a bit bigger than the hole on the lens Puma 110" SW

When was your last MOT, Jim? They shouldn't fail because of anything to do with the beam pattern but just because they've been deemed illegal. If the test was recent then you tester has either just missed them or isn't aware of the changes.

You must have used a different make, MK, because lots of us have fitted the Classic Car LED's version to our crystal headlights.

Dunno what to say then - something is clearly different
