About part number MY42-13A421-AC

A tail light is an electrical illumination component that forms part of the vehicle's exterior lighting system. Mounted at the back of the vehicle, it connects to the main wiring harness and houses bulbs or light-emitting diodes that illuminate when the driver operates the light switch or applies the brakes. When functioning correctly, it helps the driver remain clearly visible to trailing traffic in darkness or poor weather.

To confirm that this component is the correct item for your vehicle, you must check that your original part displays the manufacturer part number MY42-13A421-AC. This number is typically stamped or printed onto the plastic rear housing or mounting casing on the back of the unit. Matching the exact part number is the only way to ensure correct fitment and function.

Tail lights are commonly replaced after sustaining physical damage, such as cracks or water ingress from a light impact, or due to internal electrical failures. When installing a replacement light, a technician or owner often requires fresh fixing clips, replacement bulbs, or a new foam sealing gasket to prevent water leaking into the bodywork.
