| SCANIA 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 |
|---|---|
| Mechanical flasher with bimetallic strip | Electronic unit provides consistent flash rate and longer life; mechanical units degrade with vibration and temperature |
| Used or reclaimed flasher units | New units carry a 12 month warranty from B/L date; reclaimed stock carries none and may have hidden faults |
Use Guide
- Confirm the truck is a 24V system before fitting
- Match the 16-pin housing against the old relay before ordering
- Isolate the battery, unplug the failed flasher from the relay panel and fit the replacement in the same orientation
- Test turn signals and hazard lights in all positions before releasing the vehicle
- If the flasher does not operate, check the fuse, bulb status, and earth connection before condemning the unit
