F and E mark rear lights.

[Eternal]

After doing a bit of reading on the forum i have noticed people saying that rear lights now have to have F mark on them as well as E mark? Just a little confused as to exactly what is required.

What I'm looking for is a rear light set (but individual lamps) that has the markings required for current IVA. 90mm - 110mm in dia and not too deep as i have big wheels in my arches and don't want them to rub the rubber. If anyone has any links to some that might fit the bill please let me know Oh and looking to spend around £50-70

Thanks guys
