How do I troubleshoot the intermittent brake light on my Audi 80?

Recently, the brake light on my Audi 80 has started to turn on and off randomly while driving. This is concerning and I want to make sure it is not a safety issue. How can I diagnose and fix this problem?

First, check the brake light switch located near the brake pedal. It may be loose or worn out, causing the intermittent behavior. If that doesn't fix the issue, inspect the wiring and connectors for any damage or corrosion.

Another possible cause could be a faulty brake light relay. This can be tested by swapping it with a known working relay. If the problem persists, it may be time to replace the relay.
