I in no way stipulated that the washers are to directly cool the lights.
My understanding was that the focused light output heats up the dirt - which in turn heats up the lens. It's called conduction (I'm sure you understand conduction with your Physics PHD!
) If there is no dirt, the light energy passes straight through the clear lens unimpeded! Simples
So in conclusion:
Dirt on the lens = heat on the lens
No dirt on the lens = no heat on the lens
The lenses will be cleaned as you clean your windscreen so as to not allow excessive build-up. 1st, 5th etc.. trigger of the screen washer.
