Worth pointing out that above headlamps when fitted with LED "bulbs" are currently illegal on cars built after 1st April 1986. Although they mis-quote the cutoff date a statement
here from the suppliers.
I originally thought that (due to the huge price) these were specific LED lights (like Wolf and others are selling), but it seems they are same ones they sell as Halogens, just with the LED upgrade in, meaning that they are illegal as you state.
You can get a set of P700's for £50 new, and ClassicCarLighting due an LED upgrade for under £50
HereSo you can get an indentical set up for less than 50% of the better car lighting set up (if you are pre 86)
