The Bosch Flasher Unit is a 12V electronic flasher with 2 terminals, identified by part number P122. It is listed with a maximum load of 89W and is sold as a single unit. For buyers matching an existing relay or flasher setup, the 2-pin terminal arrangement and 12-volt rating are the key details to check first.

This unit is described as an electronic flasher type, with Bosch listing high reliability and long life as product features. It sits in the auto electrical accessories range and is grouped with fuses, breakers, relays and switches, which makes it a sensible option where a 12V, 2-terminal flasher unit is required and the application matches the part number and terminal count.

The product carries a one-year warranty. As with any electrical replacement, the correct match depends on the vehicle or circuit setup, the number of terminals, the voltage, and the load requirement. In this case, the confirmed specifications are 12V, 2-pin, electronic flasher, 89W maximum, Bosch P122.

Application and Buying Notes

Before ordering, confirm that your existing unit is a 12V, 2-pin flasher and that the application suits an electronic flasher design. The most important matching points here are the voltage, terminal count, and part number P122. If your original unit uses a different terminal arrangement or load rating, it is not the same part.

The listed maximum load is 89W, so it is worth checking the circuit requirements of the vehicle or accessory arrangement before purchase. A flasher unit should be selected to suit the intended electrical load, not just the physical plug style. Matching the voltage alone is not enough if the terminal layout or load specification differs.

Bosch identifies this unit as part of its auto electrical accessories range, and the product is sold as each. That makes it suitable as a direct replacement in setups that already use this exact style of flasher, but the safest approach is always to compare the old unit’s markings and connector layout against the P122 identification before fitting.

The one-year warranty applies to the part as supplied, but warranty cover does not replace proper fitment checks. If you are working from a vehicle with an existing flasher relay or indicator circuit issue, it is still important to confirm the fault is actually with the flasher unit and not with wiring, lamps, grounds, or the load on the circuit.

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 P122 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.

Bosch Flasher Unit 12v 2 Pin. Part number P122 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number P122, 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 voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm compatibility by checking the existing part number, terminal count, voltage, and load requirement against Bosch P122 before purchase or installation.
