Thunder Flasher Relay 3 Pin 12V Electronic Magnetic Non-polarised 126W TDR11054

The Thunder Flasher Relay is a 3 pin, 12V electronic flasher unit with a maximum output of 126W. It uses 3 blade terminals, is non-polarised, and is listed as a magnetic type, which makes it a straightforward option where a universal 12V flasher relay is required.

This unit is supplied as part number TDR11054 and is sold each. The listed maximum load is 21–23W per globe, with capacity for up to 6 globes, so it suits applications where the lamp load needs to stay within that range.

At just 0.1kg, this is a compact electrical component designed for general auto electrical use. The product group places it under fuses, breakers, relays and switches, which is useful when matching it against an existing flasher relay or when replacing a similar 3 terminal unit.

Application and Buying Notes

Before ordering, compare the existing relay against the listed details: 3 blade terminals, 12V system voltage, and the TDR11054 part number. Those are the most practical checks for confirming whether the replacement matches the unit already fitted in the vehicle or accessory circuit.

The 126W maximum rating and 21–23W per globe limit matter because flasher performance is tied to the lamp load. If the circuit uses lamps outside that range, the flash rate may not be correct, so the load should be checked before fitting.

Because this flasher is described as non-polarised, terminal orientation is less critical than on polarised units, but the relay still needs to suit the vehicle’s electrical setup and terminal style. Universal application does not replace the need to confirm the exact relay style, terminal count and voltage.

If you are replacing a failed flasher, check the old unit for the same part number, terminal layout and voltage marking. That is the safest way to avoid ordering the wrong relay, especially where the vehicle has been modified or the original component has been changed previously.

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 TDR11054 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.

Thunder Flasher Relay, 3 Pin 12V. Part number TDR11054 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 TDR11054, 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 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 part number TDR11054, 3 blade terminals, 12V rating and the lamp load requirements of the vehicle or accessory circuit before purchase.
