The turn signal bulb on the side view mirror on most cars can be changed by unscrewing the lens from the mirror. On some vehicles this lens slides out.
i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the lens
The focus is the point at which light rays converge after passing through a lens or reflecting off a mirror. For a concave mirror or converging lens, the focus is in front of the mirror/lens. For a convex mirror or diverging lens, the focus is behind the mirror/lens.
To change the right front amber turn signal lens on a 1990 F250, start by opening the hood and locating the turn signal assembly. Remove the screws or clips holding the assembly in place, then gently pull the assembly out. Disconnect the wiring harness and replace the old lens with the new one, ensuring it’s properly seated. Reconnect the wiring, reattach the assembly, and secure it with the screws or clips.

To change the signal lens in the bumper of a 1996 Honda Accord, first, remove the screws or clips securing the lens assembly to the bumper. Carefully pull out the lens from the bumper, disconnecting any wiring if necessary. Replace the old lens with the new one, reconnect any wiring, and secure it back in place with the screws or clips. Finally, test the signal light to ensure it is functioning properly.
There is a screw on the side of the signal, you can reach it through the middle of the bumper. unscrew that and the whole signal will come out of the bumper. pop the clips and then the lens will come off
concave lens will form exact mirror image.
Drop the tailgate and look at the side of the lens for screws.
Excellent question. The answer is actually yes! According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium. Google Lens makers formula for better understanding! NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!
