Speedometer lights not working on Golf MK4?

If the speedometer lights on your Golf MK4 are not working, it could be due to a blown fuse, a faulty bulb, or an issue with the instrument cluster itself. First, check the fuse box for any blown fuses related to the dashboard lights. If the fuses are fine, inspect the bulbs in the speedometer for any damage or burnout. If the problem persists, there may be a wiring issue or a malfunction within the instrument cluster that may require professional diagnosis.
