Hella Flasher Relay 12/24V Electronic 3 Terminals Part No. 3040

The Hella Flasher Relay 12/24V Electronic 3 Terminals, Part No. 3040, is an LED compatible flasher unit intended for universal connection of LED indicator lamps without electronic pulse. It is designed to suit 12V and 24V systems, giving it broad use across vehicles and equipment that need a compatible electronic relay rather than a standard thermal-style unit.

This relay maintains a standard flash rate of 90 +/- 30 fpm and operates on bulb and LED loads from 1W to 42W. That makes the key buying check very straightforward: match the system voltage, confirm the load range, and make sure the application can use a 3-terminal electronic flasher unit.

The housing is IP53 rated, which adds a useful level of protection for under-dash or vehicle electrical installations where a modest dust and moisture resistance rating is relevant. It is supplied as each and carries a three-year warranty, which gives extra context for buyers comparing replacement relays by part number and electrical rating.

Application and Buying Notes

When selecting a flasher relay, the most important checks are voltage, terminal count, and load range. This Hella unit is marked 12/24V and uses 3 terminals, so it needs to match the vehicle or equipment wiring arrangement before installation. If the original relay is a different terminal style or a non-electronic type, this part may not be a direct substitute.

IP53 protection is useful to know, but it does not remove the need to keep the relay installed in a sensible location and to protect the wiring connections properly. As with any electrical part, correct terminal identification and secure connections matter. If you are comparing this relay against another brand or part, use Part No. 3040 and the 12/24V, 3-terminal, 1W to 42W details as the main reference points.

For buyers replacing a flasher unit, the safest approach is to confirm the existing relay markings, wiring layout, and lamp type before ordering. This is especially important where the vehicle uses LED indicators, a mixed bulb-and-LED setup, or a non-standard electrical configuration. Matching the part number and electrical specification is usually the best way to avoid the wrong relay being fitted.

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 3040 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 12/24V Electronic 3 Terminals. Part number 3040 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 3040, 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.

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 fitment using Part No. 3040, the 12/24V rating, and the 3-terminal configuration before purchase. If the existing relay or wiring arrangement differs, do not assume interchangeability.
