Q: My Mazda license plate light is out but the bulb is fine — what’s wrong?
A: License plate light connectors are mounted in the rear bumper/trunk area, exposed to moisture and road spray. A corroded or broken connector is the most common cause of license plate light failure after the bulb has been confirmed good. Inspect the 2-pin connector before replacing the light assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
