Light Flashing Car 12 Volt using LM3900
The 12V flasher relay circuit is a crucial component in automotive lighting systems, primarily used for turn signals and hazard lights. The circuit typically consists of a 12V power supply, a flasher relay, and the associated lighting elements, such as incandescent or LED bulbs.
The flasher relay is designed to intermittently connect and disconnect the power supply to the lights, creating a blinking effect. It operates on the principle of thermal or electronic switching, depending on the type of relay used. In a mechanical flasher relay, a bimetallic strip heats up and bends to break the circuit, while in an electronic relay, a transistor or a similar component is used to control the timing of the on/off cycle.
To construct a basic 12V flasher relay circuit, the following components are typically required:
1. A 12V power source, such as a car battery.
2. A flasher relay rated for 12V operation.
3. Two light bulbs (incandescent or LED) to serve as indicators.
4. Connecting wires and a fuse for safety.
The circuit is assembled by connecting the power supply to the input terminal of the flasher relay. The output terminals of the relay are then connected to the light bulbs. A fuse should be placed in line with the power supply to prevent overcurrent situations.
When the circuit is activated, the flasher relay will begin its on/off cycle, causing the connected bulbs to blink. The timing of the blinking can be adjusted by changing the capacitor and resistor values in the circuit, if applicable, in the case of an electronic relay.
This circuit is widely used in automotive applications due to its simplicity and effectiveness in alerting other drivers of the vehicle's intentions, thereby enhancing road safety.If you have evered to use Flasher Relay 12V systematic usual mechanical , for general automobile.
