Compared With the Alternatives
| YUTONG dealer original flasher | Same fitment and pin pattern at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal 5-pin flasher | The unit matches the original YUTONG pin layout and timing, while a universal relay may require rewiring and lacks the correct flash rate |
| Used or reclaimed flashers | New units carry a 12 month warranty from B/L date; reclaimed stock carries none |
Use Guide
- Confirm the bus is a 24V system before fitting
- Match the 5-pin housing against the old flasher before ordering
- Isolate the battery, unplug the failed flasher from the relay panel, and install the replacement in the same orientation
- Test turn signal and hazard light operation, including flash rate and self-reset function, before releasing the vehicle
- If the flasher does not operate, check the fuse, wiring harness, and bulb condition before condemning the unit
