MR252921
Turn Signal Lamp Flasher Relay
Mitsubishi FUSO®

The Turn Signal Lamp Flasher Relay, also known as the blinker relay or flasher unit, is an electrical component found in vehicles that controls the rate at which turn signal lamps flash. The MR252921 model is a specific type of flasher relay used in certain truck models. When the turn signal switch is activated, the relay sends a current to the turn signal lamps to make them blink at a steady rate. It is important for this component to function properly as it ensures that other drivers on the road are aware of when a vehicle is turning or changing lanes. If the blinker relay fails, turn signals may not work at all or may blink too quickly, indicating a burnt-out bulb. The MR252921 model is designed to fit and function within certain truck models and should be replaced with an identical part if necessary for proper operation.
