I looked at these about 2 years ago when i first bought the p38 and they were about 100quid brand new. i thought after deciding to stick with the p38 as apposed to the l322 i would do a head light up grade and get the bumpers colour coded to give it a fresher look.

Anyway. this is the cheapest place ive found so far. Can anyone better??

Range Rover P38 Clear Lamp Set [P38lampset] - £160.00 : RJS Land Rover Spare Parts, Specialist suppliers of Land Rover parts for all Land Rover Vehicles

Yeah..the prices have gone up considerably. Try the usual suppliers such as Rimmers, MM 4X4, Paddocks, Craddocks, Island, Famous Four etc.
I don't believe that there are spurious sets out there, they tend to be OEM (Valeo) etc.
