Having read all the threads and posts on the subject I'm left baffled as to sources confused2 So please double check Paul but my research suggests the wiper stalk assembly fitted to a range of Land Rover's is Lucas STC4016. Click below for source.

The matching light switch is Lucas STC4017 (SQB160) which I have just ordered as a spare as mine can cause intermittency if turned too far.

Prices vary enormously with wiper switch the more expensive but you can buy the pair new for under £100 here delivered.

Note above are switches only not the central indicator self cancelling mechanism.
