Also, are xenons significantly better than LEDs?.
I've gained the impression that LEDs are more ruggedly reliable, use less power, and are cheaper, is that a fair summation?.In tests the LEDs are better - but that's mostly the original ones (fitted from the factory)...
many car companies (like Porsche) went from Xenons to LEDs and on their 911 it should give about 20% better lightning AND 'smarter' lighting (with adaptive lengh, cornering etc. )

All a bit of a grey area really. HID's were meant to be fitted with washers, as the lights could dazzle off refractions on dirty lenses. Also they should be fitted with projector lamps( the glass convex in front of the bulb).Think LED's are Legal it was the xenon or something headlight conversion that was illegal because they would dazzle oncoming cars something to do with the reflector. this is remembered from deep in my tiny brain and could be a load of rubbish not sure lol
