How to fix a broken brake light on a Vauxhall Vivaro?

One of my brake lights on my Vauxhall Vivaro is not working. I have checked the bulb and it seems to be fine. What could be causing this and how can I fix it?

Sometimes, the brake light switch may be the culprit. Test the switch using a multimeter to see if it is functioning properly. If it is faulty, replace it with a new one.

In some cases, the issue could be with the actual brake light housing. Check for any cracks or damage, and replace if necessary. It is also a good idea to clean the housing and the connections to ensure a proper connection.

First, check the brake light fuse. If it is blown, replace it with a new one. If the fuse is not the issue, then it could be a wiring problem. Check the wiring and connections for any damage or loose connections. If necessary, replace or repair any damaged wiring.
