vilkkurelettia
Vilkkurelettia, often referred to as a flasher relay or turn signal relay, is an electrical component commonly found in vehicles. Its primary function is to control the blinking operation of a vehicle's turn signals. When the turn signal switch is activated, it sends a signal to the vilkkurelettia, which then interrupts the flow of electricity to the turn signal bulbs at a regular interval, causing them to flash on and off. This visual cue alerts other road users of the driver's intention to change direction.
The vilkkurelettia typically contains an oscillating circuit. Older mechanical relays used a bimetallic strip that would
