Electronic Flasher Relay | Honda CB175 / CB200 / CB350 / CB360 / CB450 / CB500 / CB550 / CB750
If your turn signals stay on solid, flash erratically, or you are converting to LED bulbs — this electronic flasher relay is the fix. Unlike the OEM thermal flasher that depends on high current draw from incandescent bulbs, this solid-state relay works with both incandescent and LED turn signals. No load resistors needed.
Why You Need This
The original Honda thermal flasher relay uses a bimetallic strip heated by current flow to create the on-off flash pattern. It depends on the higher current draw of incandescent bulbs to generate enough heat to cycle. When you swap to LED turn signals — which draw far less current — the thermal flasher will not trigger. Your signals stay on solid or do not light at all.
This electronic relay uses a solid-state circuit with a low current threshold, so it flashes reliably with LED bulbs, incandescent bulbs, or a mix of both. It is a direct plug-in replacement for the OEM thermal relay — same two-terminal design, same wiring connector. If your original relay has simply failed from age, this electronic version is the upgrade path whether you are running LEDs or not.

Note: This relay is polarity-sensitive. If the turn signals turn on but do not flash, the wiring is reversed — swap the two connections. The black wire (12V+) goes to the + terminal, the gray wire goes to the – terminal.
Installation
Difficulty: Beginner
- Locate the flasher relay — on most models it is mounted under the seat near the battery or inside the headlight bucket.
- Pull the two-wire connector off the old relay and remove it from the mounting bracket.
- Connect the new relay: black wire (12V+) to the + terminal, gray wire to the – terminal.
- Turn the key on and test both turn signals.
Troubleshooting: If the signals turn on but do not flash, the relay is connected backwards — reverse the two wires. Also check your connectors for corrosion and inspect the left-hand control switch to make sure it is making good contact.
