Pendrive Style 3 Pin EV Indicator Flasher

The FLASHER [PENDRIVE] (3 PIN) (0b15) is a compact, plug-and-play indicator control module engineered to manage turn signal blinking and hazard light synchronization across various electric vehicles, including e-bikes, e-scooters, and electric three-wheelers. Named for its ultra-compact "pendrive" form factor, this 3-pin flasher unit offers a space-saving design that fits easily inside tight handlebar fairings and crowded electrical junction spaces.

Built to operate across a broad 12V – 60V DC auxiliary voltage range, the 0b15 flasher regulates electronic turn signal circuits with a steady, predictable flash rate. Its 3-pin terminal interface provides enhanced circuit control—delivering reliable power distribution, precise timing, and ground reference for modern LED and bulb indicator systems without overburdening the vehicle's onboard DC-DC converter.

Key Features

Ultra-Compact "Pendrive" Form Factor: Minimalist profile designed to fit effortlessly into cramped wiring harnesses and small fairing cavities.

Wide Operating Voltage Range: Functions reliably on 12V to 60V DC auxiliary inputs, matching diverse EV lighting sub-circuit configurations.

Stable 3-Pin Timing Control: Delivers a consistent 60–90 cycles per minute flash rate for maximum indicator visibility and clear road signaling.

Low Power Consumption: Highly efficient electronic internal relay ensures minimal power draw from the main battery system.

Durable Enclosure: Tough, splash-resistant ABS housing protects internal timing circuits against road vibration, dust, and moisture.

3x Male Spade Pin Terminals (integrated connector interface for direct plug-in connection)

Suitable For & Applications

Suitable Vehicle Types & Applications

Compact Electric Scooters & E-Bikes: Small-profile indicator controller ideal for two-wheelers with limited space inside handlebar shrouds or fairing assemblies.

Electric Rickshaws & L5 Three-Wheelers: Dependable flasher module for controlling left/right turn signaling and hazard flashers in commercial urban transport.

Custom EV & Prototype Builds: Versatile plug-and-play indicator relay for custom electric vehicle conversions, DIY mobility projects, and low-speed electric platforms.

System & Electrical Compatibility

Wide 12V–60V DC Auxiliary Voltage System: Operates directly across standard 12V DC to 60V DC auxiliary lighting sub-circuits supplied by onboard DC-DC converters.

Standard 3-Pin Wiring Harnesses: Compatible with standard 3-wire handlebar turn switches, hazard buttons, and relay wiring sockets.

Narrow-Space Installation: "Pendrive" form factor fits into tight wire routing channels, dense junction boxes, and compact headlight housings.

1. Isolate Vehicle Power & Access Flasher Mount:

Turn off the ignition, switch off the main circuit breaker, and disconnect the battery supply. Dismantle the front fairing shroud or headlamp casing to gain access to the turn signal switch wiring harness.

Verification: The instrument cluster, lights, and electrical accessories remain unpowered.

2. Position the Pendrive Unit:

Locate a clean, dry spot inside the fairing frame or handle neck to place the FLASHER [PENDRIVE] (3 PIN) (0b15).

Verification: The flasher is secured tightly against the internal housing so it does not rattle or interfere with handlebar steering.

3. Connect the 3-Pin Wiring Interface:

Attach the female socket or terminal leads from the vehicle signal harness onto the 3 male spade pins on the flasher module:

Pin 1 (Power Input): Connect to the switched +12V–60V DC line coming from the ignition or DC-DC converter.

Pin 2 (Signal Output): Connect to the load input of the handlebar turn signal switch.

Pin 3 (Ground / Reference): Connect to the vehicle's return ground (GND) wire.

Verification: Connectors click or slide firmly into place without exposing bare metal pins or wires.

4. Reconnect Power & Confirm Flasher Operation:

Reconnect the main battery, switch the ignition ON, and operate the handlebar turn signal switch for both left and right directions.

Verification: Both left and right turn signal lights flash steadily at a rate of 60 to 90 blinks per minute, cutting off instantly when turned off.

Power Isolation: Always trip the main circuit breaker and disconnect the traction battery pack before handling or inspecting the 3-pin flasher unit.

Moisture Inspection: Regularly check the ABS plastic housing and wire insertion points for cracks, water entry, or severe road grime accumulation.

Terminal Integrity: Inspect the 3-pin male spade connectors to ensure female wire harness sockets are seated tightly without corrosion or rust.

Load Balance Check: Verify that connected LED or bulb turn indicators do not exceed the module's 1.5A current rating to prevent rapid blinking or thermal overload.

Firm Mounting: Ensure the lightweight pendrive body remains securely zip-tied or bracketed inside the handlebar fairing so vibrations do not pull or strain the wiring harness.
