The signal light fuse can burn due to several reasons, including a short circuit in the wiring, excessive current draw from the signal lights, or a faulty component. When the electrical flow exceeds the fuse's rated capacity, it heats up and ultimately burns out to protect the circuit from damage. Additionally, poor connections or corroded terminals can increase resistance, leading to overheating and fuse failure. Regular maintenance and inspection can help prevent such issues.
The Turn Signal and Brake Light may be operating from the same Bulb, or separate bulbs. Regardless, the Brake light filament must be burned out. Another option is that the Brake Light Circuit is on a separate Fuse, and the Fuse is blown. Check for those possibilities.
If your light is solid 1 bulb is burned out or if no lights blink it is a flasher located in your fuse box
If you are getting an indicator of a burned out light, but don't see a burned out light, it must be a turn signal light. On a Mercedes, you'll actually get a "burned out light" indicator if the turn signal is not working.
A light bulb or a fuse.
Check the signal light fuse, the signal light relay, and the signal light switcher.
The bulbs may be burned out, or a fuse may be blown.
If the signal light on a 1997 C280 isn't working, it could be due to several reasons. Common issues include a blown fuse, a faulty turn signal relay, or burned-out bulbs. Additionally, wiring issues or a malfunctioning switch could also cause the signal light to fail. Checking these components systematically can help identify and resolve the problem.

A blown fuse or burned out bulb
If the signal light fuse is blown all the signal lights front and rear would not work. If you have one signal light out I would first suspect a bad bulb or bad connection.
