The LED flasher module is an important device for your vehicle. For instance, you can use the LED flasher on the indicators/ turn signals of your vehicle. The module consists of different parts that we shall discuss in this article. Additionally, you shall get everything you need to know about LED flasher by the end of our article.
What is a LED flasher module?
The LED flasher module is an electronic gadget for use on vehicles that uses LED lights. The gadget is in a solid-state form. The flasher helps offset low amperage draw where light emitting diodes operate. However, this device does not cause quick flashing.
Moreover, the flasher module comes with a superb ability to regulate your vehicle’s light emitting diode indicators’ flash rate. This includes light, deck, fog, and grill lamps on your vehicle. In this article, we are going to give you more details on the LED flasher module.
LED Flasher Circuit
The LED flasher module comes with an integrated circuit regulator for in-built lamp outage displays. Therefore, it would be best to control your vehicle’s LED lighting with a LED flasher module unit.
The Types of LED Flashers
Generally, two types of light emitting diodes flashers according to the mechanism they use to control light. They include Relay and Solid state. The Relay flasher uses an electromechanical relay on the final switching, while a solid state flasher does not have any moving parts. It uses a semiconductor power transistor found inside the device on the final switching. Below is a highlight of different types of LED flashers based on the two mechanisms.
LED Flasher Relay Motorcycle
The LED flasher relay motorcycle works uniquely. A double metallic strip heats up as the current flows through it then opens up. After switching off the current, the metallic strip cools and closes again. The LED flasher relay flashes faster or even stops when the bulb blows out since little or no current is flowing.
No Load LED Flasher
No Load LED Flasher allows you to install LED turn signals with a moderate flash. Do not forget that the metric model repeatedly alternates, which may not be a solution to rapid flash.
Emergency Light Flasher Module
Emergency light flashers are also known as hazard lights. These lights become active immediately the driver pushes the hazard light switch. They warn other motorists of an emergency condition you are in or to show that you’ve packed your car on the roadside. As long as your turn signal lights are on, your emergency flasher is active.
How to Install LED Flasher Module
Step 1: Identify and detach the LED Flasher Unit
Firstly, locate and detach the flasher unit. The location is not the same on all vehicles. Otherwise, get in touch with your service manual to help you locate the flasher unit. Alternatively, you can switch on the turn signal lights and listen to the clicking noise.
Step 2: Get the Old Circuit out of the LED Flasher unit
Most of the flasher units are disassemble. If you can disassemble it, please do so. If not, since they have a pot on the timing circuit, use a hacksaw to cut the flasher case open.
Step 3: Reconnect the Original Connector
You can re-use the initial connector and fix your new circuit onto it using a solder.
Step 4: The LED Flasher Circuit Chart
The new LED flasher circuit features a power transistor and a 555 timer circuit. It comes with a robust power transistor rated at 10A. Besides, you can regulate the flash rate and duty cycle to C1, R1, and R2. For C and R values, the flash rate is about 85 flashes per minute or 85 Hz. If Google is your friend, you will find much information on the 555 timer, such as using programs to calculate the C and R values.
Step 5: Retrofit the New Circuit
Solder the new circuit using a point-to-point connection to the original connector. It is not appealing, but it works perfectly. Additionally, an oscilloscope may be handy at this point if you wish to repair the circuit. If everything is done as per the requirement, your LED will flash at the required rate.
Step 6: Button It Up
Test everything to ensure it is working as it should be. After that, use epoxy glue to seal and enclose the new circuit onto the original casing’s bottom part. After the epoxy glue dries up, re-install the flasher in your Concours.
Step 7: Fix Voltage Filter Cap for V12V Voltage Ripple issues
A filter cap C3 is essential for the circuit. It corrects the problems arising from too much AC ripple power on the V12V power supply. This problem mainly occurs when the vehicle is running over 2000 RPM. At this point, the value of C3 is not the best, but any value over 1000uF should work perfectly. The C3 should be very close to U1 to increase its efficiency.
Will Led Flasher Work with regular bulbs?
Yes. All LED flashers work perfectly with regular bulbs, LED bulbs, and regular bulbs/mix LED bulbs. These flashers range from CEC to Solid State flashers.
How do you know if a flasher relay is bad?
Typically, a bad flasher relay produces a few signs that may alert you that something is not working well. These signs may include:
- Hazards or turn signals do not go off
- Extra lights are not working properly
- Turn signals or hazards may fail completely
Do I need a resistor for a relay?
A resistor is crucial for your LED flasher module in a situation where you are supplying a higher voltage than the rated one for your relay. If you are using less voltage than the rate on your relay, you do not require a resistor.
Having an LED flasher module on your vehicle should be the best thing to consider. As seen from this article, installing a LED flasher module is not a big deal. You need to assemble the required materials and fix the device on your vehicle. Additionally, the LED flasher module is straightforward to identify in case of any failure.
