Interesting to read that the H4 LED replacement bulb is now legal to fit in cars following a 2023 announcement.In the classic car automotive world many filament lamps now have a direct LED replacement:
Classic Car LEDs Ltd
High quality LEDs, Relays and fittings for Vintage Classic and Modern Cars, Motorcycles and Caravans at great value prices. Designed as a straight replacement for standard Incandescent bulbs. Long term Classic owners that know the benefits these LEDs bring. LED Bulbs and Globes.www.classiccarleds.co.uk
Looking on Philips own website, none of their LEDs are compliant with ECE R37 - although they are with ECE R10 which is just electromagnetic limits.UKDave
I have been looking at the Phillips H7 led Classic car replacement bulbs. But although they are a direct replacement fit the suppliers are still saying that they are not EU marked and not UK road legal. Where was the changed status for UK published?
