Sorry to bring up a well worn topic but I've had a long search and can't find answer to my specific problem.
Getting sick of poor headlamp performance and purchased HID kit from ABD after seeing members giving the kit a positive review. Removed headlamp to start fitting and am convinced my reflector has degraded, no point fitting kit until this is fixed. Looks fairly simple to remove reflector on the YouTube clips I watched. In my case (2013 MY) two of the screws holding the reflector and lens are partially obscured by the white bracket, see pic.
Can anyone advise how to remove lens & reflector and where can I buy replacements?
Thanks in advance

is this of any use ??

I have adapted many projector style headlights from RHD to LHD, by dissasembling the units and modifying the beam plate. However I failed to dissasemble the headlights on a friends 13 plate as I hit the same problem as you have and could not get the unit apart.
All I can say is be careful not to damage your existing headlight units.
There are few if any second hand units about, and I ended up payong €1200 to get a set of LHD headlights from Landrover as no one else could supply them

In the end I ground away a bit of the plastic to expose the screws, waste of time as it turned out as reflectors are in good shape. I've fitted the HID kit, not been out in the dark yet, will hopefully get out soon.
Gave up looking for used xenon headlights, can't believe the prices being asked. HID kit was £60, the same as 2 or 3 sets of bulbs.
Thanks for the replies

Well Done ! I was too nervous to modify the internals to enable dissasembly as the headlights were not mine and the costs of replacement expensive. I managed to sell the RHD units for £500 the pair, so recouped some of the outlay for the LHD units.
