999+ Things to Know About Flasher Relays for LED Lights

What is a Flasher Relay?

A flasher relay is an electrical device that controls the flashing of a turn signal or hazard light. It is typically located under the dashboard of a vehicle. When the turn signal or hazard light switch is activated, the flasher relay sends power to the turn signal or hazard lights, causing them to flash.

How Does a Flasher Relay Work?

A flasher relay works by using a bimetallic strip. When the bimetallic strip is heated, it bends, which opens a contact. This interruption of power causes the turn signal or hazard lights to turn off. As the bimetallic strip cools, it straightens, which closes the contact and turns the turn signal or hazard lights back on.

Types of Flasher Relays

There are two main types of flasher relays:

• Thermal flasher relays use a bimetallic strip to control the flashing.
• Electronic flasher relays use a solid-state circuit to control the flashing.

LED Lights and Flasher Relays

When using LED lights with a flasher relay, it is important to use a flasher relay that is compatible with LED lights. This is because LED lights draw less power than incandescent bulbs, which can cause the flasher relay to malfunction.

Symptoms of a Bad Flasher Relay

There are several symptoms that can indicate a bad flasher relay, including:

• The turn signals or hazard lights do not flash
• The turn signals or hazard lights flash too fast or too slowly
• The turn signals or hazard lights stay on solid

How to Replace a Flasher Relay

Replacing a flasher relay is a relatively simple process. Here are the steps:

1. Locate the flasher relay. It is typically located under the dashboard of the vehicle.
2. Disconnect the electrical connector from the flasher relay.
3. Remove the flasher relay from its socket.
4. Insert the new flasher relay into the socket.
5. Connect the electrical connector to the flasher relay.

Troubleshooting Flasher Relay Problems

If you are having problems with your flasher relay, here are a few things you can try:

• Check the electrical connections to the flasher relay.
• Replace the flasher relay.
• Have the electrical system of your vehicle inspected by a qualified technician.

Conclusion

Flasher relays are an important part of the electrical system of a vehicle. They control the flashing of the turn signals and hazard lights. If you are having problems with your flasher relay, it is important to replace it as soon as possible.
