It is illegal to change the head lights from halogen to LED.

This web document updated at 2018 discusses LED headlights about halfway down, with references to various official regulations -Source please! An authoritative one if possible.
It might be worth noting that factory LED headlights are designed as complete units, and replacing factory halogen headlight bulbs with LED bulb replacements will not necessarily give the same results.
according to this: https://www.powerbulbs.com/blog/2019/04/led-headlights-road-legalTry finding an led replacement bulb that states it is suitable for use on the public road.
What I have not seen from any company selling upgrade bulbs is any explanation of the actual change of distance with more powerful lights, for seeing objects further away with the same brightness.I do not understand the obsession people have with LED lights. They are too bright sometimes, dangerous for oncoming drivers. How did people survive before LEDs with normal halogen headlights? Surely we should all be dead because they are too dim and dangerous
some matrix LED lamps can be adaptive and will change the beam shape according to incoming lights, thus avoiding dazzling other drivers.I note that VW say the top spec ID3 has "matrix LED headlights". Not sure exactly what those are. I also wonder what the lower spec versions get.
Well it seems I didn't get that explanation across at all well!I think your calculations are out. The loss over the distance is a proportion. So if you start at X lumens from the headlight and are down by A% at the target, and then down by B% as the light returns, but then you change the light to Y lumens, you're still down by A% and B%.
My e-Kona equipped with halogen headlights has auto dipping when it detects the headlights of an oncoming vehicle. It seems to actuate faster than I can with manual dipping...some matrix LED lamps can be adaptive and will change the beam shape according to incoming lights, thus avoiding dazzling other drivers.
They are absolute magic.I note that VW say the top spec ID3 has "matrix LED headlights". Not sure exactly what those are. I also wonder what the lower spec versions get.
Ah, I see, I was only thinking of the same distance but different brightness, you're talking the overall losses for combined distance.Well it seems I didn't get that explanation across at all well!
As I explained previously, the fourth power of distance is the basis of the calculation of the required light outputs for the different distances.
Especially as they don’t bother to press charges against the idiots (majority?) who seem to think it’s fine to ride without any lights at all.I compare this situation with the one for bicycles where in law, LED front and rear lights are technically illegal especially flashing but no sane law enforcement agency would press charges.
