Don't think they will last long, just bought 2 sets and a spare set

used them for years on a landrover never had an issue. side on the dont offer much light though. they do have E mark?? though

I have just bought some yesterday however they weren’t those. I got mine from this website. there are lots of other lights on there aswell - annoying thing is you have to spend £50 to get free delivery.

These were highly recommended to me and are used for busses and other commercial vehicles. Thought I would give them a try.
