MFC PRO 12V 3-Pin Electronic LED Flasher Relay FLR-MFC2 — Fixes Hyper-Flash, 1.4–1.6 Hz

MFC PRO FLR-MFC2 is a compact 12V electronic 3-pin flasher relay designed to correct hyper-flashing and non-flashing issues with LED turn signals on many motorcycles. The FLR-MFC2 replaces bulky mechanical relays with a chip-controlled electronic unit that detects load and provides a steady 1.4–1.6 Hz flash rate. Sized at 30 × 30 × 18.5 mm and supplied with a short extension lead, it’s built for straightforward installation on bikes that use a three-wire flasher connection. Because it’s an electronic device, proper grounding of the white (negative) wire on some systems is required for reliable operation.

How does this relay stop hyper-flashing on LED turn signals?

The FLR-MFC2 uses an internal controller to produce a consistent flash cadence close to OEM rates, compensating for the lower resistance of LED bulbs compared with incandescent lamps. When installed correctly, it prevents the rapid flash common when LEDs are fitted without added resistors.

• Chip-controlled timing: 1.4–1.6 Hz (85 ±15 c/m) at DC 12V.
• Works without adding heavy resistors in most setups.
• Designed to recognize power automatically after switch-on.

Will this relay fit my motorcycle and how do I install it?

The relay measures 30 × 30 × 18.5 mm and features three wires plus an extension lead for flexible mounting. Compatibility covers a wide range of North American sportbikes and cruisers; always verify dimensions and wiring before buying.

• Compact footprint fits behind panels or under seats.
• Check that your bike uses a 3-pin flasher wiring pattern before replacement.
• White (negative) wire may need grounding on some models for full function.

What common problems should I watch for after installation?

If the flasher doesn’t operate as expected, it’s usually due to incorrect wire connections, a missing ground on the white wire, or an incompatible wiring scheme. The product ships with an extension lead to assist reconnection, and customer support is available if the unit appears inactive.

• Ensure three wires are correctly matched to your harness — incorrect wiring prevents normal operation.
• Ground the white wire on models that require a negative pole connection.
• Contact support promptly if the relay appears dead or flashing remains irregular.

What electrical specifications and limitations should I know?

This FLR-MFC2 is rated for DC 12V operation and produces a fixed flash frequency suitable for LED turn signals; it is not a multi-voltage unit. It does not include batteries and is intended for vehicles with compatible 12V systems.

• Operating voltage: DC 12V.
• Flash frequency: 1.4–1.6 Hz (85 ±15 cycles per minute).
• Physical size: 30 × 30 × 18.5 mm; check fit before purchase.

Who is this for This relay is for riders who have upgraded to LED turn signals and now face hyper-flashing or intermittent indicator operation. It suits mechanics, DIY motorcycle enthusiasts, and anyone with a compatible 3-pin flasher wiring layout on sportbikes and cruisers who wants a small, electronic replacement to restore stable signaling without adding bulky resistors.

FAQ

Q: Does the FLR-MFC2 work with any LED turn signal?

A: It works with most 12V LED signals but confirm your bike uses a 3-pin flasher wiring and check the relay’s dimensions first.

Q: What if the flasher doesn’t work after I install it?

A: Verify three-wire connections and ground the white wire if needed; contact seller support if problems persist.
