12V 2-Pin LED Flasher Relay – Stop Hyper-Flash Without Resistors
Have you upgraded your motorcycle or scooter to LED indicators, only to find them flashing erratically or at double the speed? The issue isn’t the LEDs—it’s your original relay, which isn’t designed for the low power draw of LED bulbs. This 12V 2-pin LED flasher relay solves the problem instantly with a simple plug & play installation, requiring no modifications to your wiring.
Note: Before installation, please ensure your vehicle uses a 12V electrical system and that your current relay features a 2-pin configuration (B – input, L – output).
Why choose this model? (Key Benefits):
- Eliminates hyper-flash permanently — Operates stably from as low as 0.6W, meaning it works perfectly with low-power LEDs without the need for heat-generating load resistors.
- Adjustable frequency (50–200 flashes/minute) — Fine-tune your flash rate using a small screwdriver directly on the unit, no extra parts required.
- Compatible with halogen bulbs — Supports up to 2 x 21W + 3.4W for dashboard indicators, making it suitable even if you retain original bulbs on the front or rear.
- Triple integrated protection — Features built-in short-circuit, overload, and reverse polarity protection; accidental miswiring won’t damage the unit.
- Weather-resistant (-40°C to +80°C) — Housed in a durable, shock-proof, and water-resistant ABS casing suitable for all weather conditions.
- Under 10-minute installation — Replaces your original relay directly with no cutting, splicing, or professional assistance needed.
Performance and Specifications
Built on an SMD electronic platform, this relay is incredibly compact—measuring just 3.5 x 3.5 x 2.7 cm and weighing only 20g—offering superior reliability compared to traditional electromagnetic coil relays. The 0.02A minimum switching current ensures it detects even 0.6W LEDs without causing flickering or irregular patterns. The 11V to 15V operating range covers the standard voltage fluctuations of any 12V nominal battery system without risk of overvoltage during charging.

Installation and Adjustment Guide
- Disconnect the vehicle battery before starting any work.
- Locate your original 2-pin flasher relay and remove it from its mount.
- Connect the new relay: Pin B to the input wire (power from ignition), Pin L to the output wire (leading to the indicators).
- Reconnect the battery and test both front and rear indicators, as well as the dashboard warning light.
- To adjust the flash rate, locate the adjustment screw on the casing: turn clockwise for a slower flash, or counter-clockwise for a faster flash (50–200 flashes/minute).
- Ensure the dashboard indicator synchronises with the external lights; once it flashes correctly, your installation is complete.

Frequently Asked Questions
Does it really eliminate hyper-flash without extra resistors?
Yes. The relay is designed to detect loads as low as 0.6W, so it does not require load resistors to simulate a halogen bulb. The flash rate remains consistent regardless of the LED power.
Can I use this with original halogen bulbs instead of LEDs?
Yes. It supports up to 2 x 21W plus 3.4W for the dashboard indicator, which is the standard configuration for most motorcycles and scooters using original bulbs.
What happens if I connect the pins incorrectly?
The relay features integrated reverse polarity protection. An incorrect connection will not damage the unit, though we recommend verifying the input and output wires before powering on.
Is it compatible with electric scooters or e-bikes?
Yes, any vehicle with a 12V nominal electrical system (11V–15V) and a 2-pin relay connector is compatible. Please verify your system voltage before ordering.
How do I adjust the flash speed after installation?
There is a small adjustment screw on the casing. Use a precision screwdriver to turn it until you achieve your desired rhythm—the available range is 50 to 200 flashes per minute.
