Do your pop-up headlights jiggle? It's annoying to you and to other drivers, especially if you're running good lights with a sharp cutoff.
You don't need to put up with that. Your headlight arm bushings are worn out or even missing. The arm connects the motor to the actual headlight, so it's critical for a stable headlight. This factory part has fresh bushings in it and installs in seconds with a flat-head screwdriver. End the jiggle!
Mazda factory part NA01-51-SA5. Sold individually, one per headlight.
