Tridon EP35 Electronic 12V 3 Pin Flasher Unit

The Tridon EP35 is an electronic flasher unit for 12V systems, supplied as a 3 pin unit and identified by part number EP35. It is described as load sensitive and suitable for flasher and hazard light applications, with an operating range of 9 to 16 volts D.C.

This unit carries a load rating of 2 + 1 (6) x 21W and incorporates audible, visual globe failure (outage) indication. That makes the EP35 relevant where the vehicle’s indicator or hazard circuit needs an electronic flasher rather than a thermal style unit.

The EP35 is listed as conforming to SAE, ISO and ADR13 requirements, and it is supplied boxed. It is also noted as superseded by Fet13, so matching the part number and application details is the safest way to confirm the right replacement before ordering.

Application and Buying Notes

Before ordering, check that your vehicle uses a 12V, 3 pin flasher unit and that the circuit requirements suit a load sensitive electronic unit like the EP35. The stated operating range is 9 to 16 volts D.C., so this is intended for systems that sit within that window.

The load rating of 2 + 1 (6) x 21W is a useful guide when comparing against the original unit. If the original part uses a different pin count, voltage range, or load specification, this unit may not be the correct replacement even if the connector looks similar.

The EP35 is listed for flasher and hazard light applications and includes audible, visual globe failure indication. That feature is relevant when you want the unit to warn of a lamp failure, but it still needs to match the vehicle’s electrical setup and the original part number where possible.

Tridon also notes that the EP35 has been superseded by Fet13. If you are cross-checking against an older vehicle or an existing flasher relay, confirm the original application details carefully before fitting. Using the part number EP35 and the vehicle’s electrical specifications together is the most reliable way to avoid a mismatch.

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 EP35 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.

Relevant published details for this unit include Type FLASHER UNIT, Unit of Measure EACH, Warranty One Year, Number of Pins 3, Product Group 1 AUTO ELEC ACCESSORIES, Part No. EP35, Brand TRIDON, Description Flasher Unit - Electronic 12V 3 Pin Outage Boxed, Voltage 12.

Flasher Unit - Electronic 12V 3 Pin Outage Boxed. Part number EP35 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 EP35, 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.

Available application references include BMW 3, BMW 3 1975, BMW 3 1976, BMW 3 1977. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

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 fitment by checking the original part number, 12V system voltage, 3 pin layout, and load requirements against the vehicle application before purchase.
