Was looking around at options because apparently my LED versions won't pass the MOT this time round, what with not having a beam pattern similar to standard (despite not ever causing anyone to flash me!) and found this site - looks good in terms of OE-ness, and the output looks reasonable: vintagecarleds.com/compare-7-inch-models/
I'm not sure what the difference between the different glass lenses, or if they do RHD-spec lenses...
They need to be 'E' marked (along with some number in a circle that I can't remember) to be fully road legal - there's a million chinese LED lights available which claim to be legal which technically aren't, and also have rubbish light output..
The NA headlights are the same as Defender lights, so any of the millions of Defender suppliers have lots of options. I have Trucklite LEDs on my v8 110 which are a massive step up from the clear Raybrig/Wipac style lights with uprated bulbs (which are now on my NA).
