Seem to remember these as an option being put forward on the Lexus forum.

Owners of earlier cars mentioned them but then other people said that newer models

(iS200) had an updated washer that was better,

Not sure about how sleek the later Lexus ones are or how they get the water on the screen.

Maybe the problem wuth the

'2 is the angle of the screen.

Seem to remember there were loads of different part numbers as they come colour coded.

I'll post up anything I can find.
