Hella Flasher Relay 12V Electronic 171W Max, 4 Terminal, Part No. 3039

The Hella Flasher Relay is a 12V electronic flasher unit rated to 171W max, with 4 terminals and part number 3039. It sits in the auto electrical category and is listed as LED compatible, which makes the key electrical details easy to confirm before ordering.

As a flasher unit, this component is chosen for signal and warning lamp circuits where the relay type, terminal count, voltage, and load rating all need to suit the application. The electronic flasher type and 171W maximum rating are the main checkpoints, along with the 12V system requirement.

Hella identifies this part as a flasher relay in the Fuses, Breakers, Relays and Switches group. It is supplied as an each unit and carries a three-year warranty, giving buyers a clear reference point when replacing a matching 12V relay with the same part number 3039.

Application and Buying Notes

Before ordering, confirm the existing relay matches the key identifiers here: 12V system voltage, electronic flasher type, 4 terminals, and part number 3039. Those details matter more than appearance alone, because flasher units can look similar while differing in terminal layout or load rating.

The 171W maximum rating should be checked against the circuit it will be used in. If the replacement relay is working in a system that relies on an LED-compatible electronic flasher, the LED compatibility noted for this part is an important check. If the vehicle uses a different terminal count, voltage, or relay style, this unit should not be assumed to suit.

When replacing a flasher relay, compare the old unit carefully and confirm the terminal arrangement before fitting. Part numbers are the safest reference when available, and 3039 is the identifying number listed for this Hella unit. If there is any doubt about the application, match the original relay details rather than relying on the housing shape or a general description alone.

This relay is sold as one unit, so it is suitable where a single replacement is required. The three-year warranty provides a useful reference for the product itself, but it does not replace the need to verify the application, the 12V supply, and the 4-terminal configuration before purchase.

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 3039 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.

Hella Flasher Relay 12V Electronic 171W (Max) - LED Compatible. Part number 3039 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 3039, 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.

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

Compatibility note: Confirm compatibility by matching part number 3039, 12V operation, 4 terminals, electronic flasher type, and the 171W max rating against the original relay and vehicle application details.
