Get the units not just the bulbs, i replaced all of myn with clear lenses. Front were ok, indicators have a weaker 'angle' then the standard. Rear brake lights are fine if your directly behind or in the dark there ok but i have actually changed them now after following my landy and seeing it brake, well, not as well as i should have!
The ones i got were propper ones, extra bright LED and were 'legal' for road use, just not in a defender light diffuser it seems.
Looks sweet though with the clear lenses, still got the fronts on.
