Build Your Own Led Flashers For A Car

LEDs can also be extremely bright.

LED flashers or indicator lights are becoming increasingly popular, and more manufacturers are using LED lights on their vehicles. Creating aftermarket LED flashers and installing them on a vehicle is actually easier than it may seem and should take less than an hour. LEDs are durable, consume little power and do not become hot. Their durability is a primary reason they are a desirable light source in automobiles.


1. Disconnect the battery. This will prevent a short during installation.

2. Purchase replacement flasher and indicator housing units for your specific model vehicle.

3. Remove the flasher/indicator light housing from the vehicle. The method to remove the lights varies by vehicle, but a screwdriver should be sufficient to remove the light housing. Disconnect the two power wires from the housing.

4. Determine where the LED lights will be placed in the new housing. Arrange the lights in a uniform pattern that will look appealing and organized.

5. Glue the LEDs to the housing and run their power wires to the back of the unit. Alternatively, the LEDs can be drilled into the housing directly. This will depend on the model of the LEDs and the structure of the light housing.

6. Connect the LED power wires to the LED control module. The control module acts as a hub for all of the LED power wires.

7. Connect the control unit to the existing flasher/indicator power wires. There should be a positive and negative wire: Connect them to the positive and negative power terminals on the control module.
