How exactly do they work?

Do they simply spray washer fluid on the lights any time the windshield washer is activated? Or do they follow a different strategy?

I noticed there are different part numbers for the blinker/cruise/wiper switch assembly in the steering column but wasn't sure why.

Anyone ever retrofit them onto their car? (Including the motor, lines, etc.)

As understand it, they wash the lights when the lights are up and the windshield washer is activated.

That is it.

of course my first response was going to be....they don't

Take them out plug them and use your washer resevoir for a hydromist for your intercooler.

Intercooler sparyer....that's the way I am setting it up.

There's an electric motor in the (large) tank. When you push forward on the wiper control, it runs the motor for a short (but powerful) shot. Yes, the system is "smart enough" to know whether the lights are up or not - if they're not, the system is locked out and will not work. I recently fixed mine - it's quite nice and works very well. It's also amazing how much fluid comes out in that brief half-second "pulse" of operation too! Maybe I'll turn 'em around to shoot pedestrians in crosswalks next.

I think it'd be ineffective as an intercooler sprayer due to the high pressure of the streams. You'd have to get more "mist" and less "stream" and probably knock down the pressure a bit. Interesting thought though - evaporating water DOES have a considerable amount of cooling capacity. . .
