Application and Buying Notes

This flasher unit is intended for 12V electrical systems and the key compatibility points are the 3-pin layout, the 9 to 16 volts D.C. operating range and the 2 + 1 (6) x 21W load rating. Those details matter because a flasher relay must suit both the vehicle’s electrical setup and the lamp load it is controlling.

If you are replacing an existing unit, compare the part number FET13 and the OEM number MB338222 with the original fitted item. That is the safest way to narrow compatibility, especially where the same vehicle range may have different electrical configurations or relay styles.

The audible and visual globe failure indication is a useful feature where lamp outage monitoring is needed, but it should not be treated as a substitute for confirming the correct application. Always check pin count, voltage, load rating and the vehicle’s flasher or hazard light circuit before purchase.

The unit is described as suitable for flasher and hazard light applications, which makes it relevant in the relay and switch section of the electrical system rather than a general-purpose accessory. If you are unsure, compare the original relay markings and connector arrangement carefully before fitting.

For buyers who prefer packaged stock, this unit is also available in Fet13pac retail blister pack. The core identifying details remain FET13 and MB338222, so either presentation should still be matched by part number and application rather than appearance alone.

Because fitment information covers many makes and models, there is no substitute for checking the actual vehicle application and the existing part against the listed specifications. Matching the 12V rating, 3 pins and load-sensitive design is the most practical starting point for a correct order.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number FET13 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Tridon Flasher Unit. Part number FET13 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number FET13, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a flasher unit in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching the part number FET13, OEM number MB338222, 3-pin connector layout, 12V system requirement and the listed load rating against the vehicle’s original flasher unit before buying.
