- Locate the tail light assemblies on either side of the vehicle.
- Remove the bulbs from the tail light assembly by turning them counterclockwise.
- Inspect the bulbs for any signs of damage or burnout.
- Replace the bulbs if they are damaged or burnt out.
2. Check the brake light switch:
- The brake light switch is located under the dashboard, near the brake pedal.
- Disconnect the electrical connector from the brake light switch.
- Use a multimeter to test the switch for continuity.
- If the switch is not working properly, replace it.
3. Check the brake light fuse:
- The brake light fuse is located in the fuse box under the hood of the Miata.
- Remove the fuse from the fuse box and inspect it for any damage or burnout.
- Replace the fuse if it is damaged or burnt out.
4. Check the brake light wiring:
- Inspect the wiring for any signs of damage or corrosion.
- Check for any loose connections or broken wires.
- Repair or replace any damaged wiring.
5. Check the brake fluid level:
- Check the brake fluid level in the master cylinder, which is located under the hood of the Miata.
- If the brake fluid level is low, add more brake fluid until it reaches the "Full" mark.
