How do you change the third brake light on a mr2?

To change the third brake light on a Toyota MR2, first, locate the access panel in the rear trunk area, which may require removing some interior trim. Disconnect the wiring harness from the old light, then unscrew or unclip the light assembly. Replace it with a new light, reconnect the harness, and secure the assembly back in place. Finally, test the light to ensure it's functioning correctly.
