|---|---|
| Mechanical bimetallic flasher | The electronic unit maintains consistent flash rate under varying voltage and temperature; the mechanical version drifts with age and heat |

Use Guide
- Confirm the truck is a 24V system before fitting
- Match the 6-pin housing against the old relay before ordering
- Isolate the battery, unplug the failed flasher from the cab relay panel and fit the replacement in the same orientation
- Test left and right turn signals plus hazard function before releasing the vehicle
- If the signals flash erratically, check the bulb condition and earth connection before condemning the flasher
