Most headlight washers automatically engage after a certain number of windshield washes. So you probably have used them, but didn't know it! Unless you've never used your windshield washers. . .No i don't use windshield washers when it is raining and we don't have snow in NorCal.
Should be an option like the orange reflectors. I am just glad those are not in the headlights.
I've had headlight washers in all my cars and never used them once.
