Bosch Flasher Relay 24V Electronic 173W Max 3-TERMINAL P243

The Bosch Flasher Relay P243 is a 24V electronic flasher unit with 3 terminals and a maximum load rating of 173W. It is suited to 24V electrical systems where a 3-pin electronic flasher relay is required.

This unit is supplied as a Bosch product, listed as a flasher unit, and is sold individually as each. The compact weight of 0.042kg makes it a small electrical component, but the key purchasing point is still the voltage, terminal count, and 173W maximum rating.

When replacing a flasher relay, matching the system voltage and terminal configuration is essential. The P243 reference, 24V rating, and 3 terminal layout are the main identifiers to check before ordering.

Application and Buying Notes

For a flasher relay, the most important checks are system voltage, terminal count, and the part reference. This Bosch unit is specified for 24V systems, has 3 terminals, and carries the part number P243, so those details should be matched against the vehicle or existing relay before purchase.

The 173W maximum load rating is another useful point to confirm. If the existing relay is marked differently, or if the wiring and lamp load do not match a 24V 3-terminal electronic flasher setup, the correct replacement may be a different unit. Relay type matters as well, because this one is electronic rather than a thermal style.

If you are replacing an old relay, compare the markings on the part currently fitted, including any part number, terminal count, and voltage marking. That is usually the safest way to confirm you are selecting the correct Bosch P243 flasher relay for the application.

The small physical size and low weight do not tell the whole story with electrical parts, so use the electrical specifications first. Voltage, terminals, and maximum wattage are the practical details that matter most for selection and installation.

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 P243 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 Relay 24V Electronic 173W (Max) - 3 Terminals. Part number P243 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number P243, 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 24 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching the Bosch P243 part number, 24V system requirement, 3 terminal layout, and 173W maximum rating against the existing relay or vehicle application before ordering.
