I can maybe understand comments made by many on this thread concerning LED bulbs in halogen designed reflector bowls. Why are earlier vehicles not subject to the legislation, I've invested before, don't like the looks of modern etc etc.

The claims that they don't blind others on dipped beam are subjective though particularly to the eyesight of oncoming driver. How do they really know confused2 Could it simply be to that a Morgan's low profile reduces likelihood. Does this make them ok though under all road conditions?

Given the huge leap in brightness and colour temperature manufacturer's of full LED headlamps have gone to a lot of trouble to ensure a neccessary extremely sharp dipped beam cutoff using focused optics. I simply cannot believe that some LED bulbs from established manufacturers will perform as well in halogen reflectors despite them somehow gaining approval in some parts of Europe, although I note Heinz's doubt on this matter.

This prompted my decision some time ago, well before current legislation, to opt for modestly priced E marked full LED headlamps which use such to provide dipped beam, supplementing the separate main beam when selected. I note the E marking is not an MOT requirement BTW.

I've proven to myself that there is splatter from OE halogen headlamps on dipped beam which can only be greater with a much brighter light source as below.
