How to replace taillights?

To replace taillights, first ensure your vehicle is turned off and parked safely. Open the trunk or hatchback to access the taillight assembly, then locate the screws or clips holding it in place. Remove these fasteners, gently pull the taillight assembly out, disconnect the wiring harness, and then replace the old bulb with a new one or install a new assembly. Finally, reconnect the wiring, secure the assembly back in place, and test the lights before closing everything up.
