Thunder OE Style Push Button Switch Lightbar 12V 3A TDR11085

The Thunder OE Style Push Button Switch Lightbar is a 12V switch rated at 3A, supplied as one each and identified by part number TDR11085. It is an OE style push switch with On - Off - SPST action and blue LED illumination, making it suitable where a compact illuminated control is required for a lightbar or similar 12V accessory circuit.

Physical size is an important check on this item. The mounting dimensions are 38.6mm x 22.5mm, so the panel opening needs to suit those measurements before purchase. The switch wiring is also clearly defined: black for earth, blue for dash light circuit if used, red for 12V input, and green for 12V output.

Listed application coverage includes Isuzu and Holden vehicles, with specific references to Isuzu D Max 2009-2012, Holden Colorado 2008-2012, and Holden Rodeo 2003-2008. Even with those applications shown, matching the switch to the vehicle’s dash opening and wiring arrangement remains the most important installation check.

Application and Buying Notes

Before ordering, check the part number TDR11085 against the switch you are replacing and confirm the panel opening matches 38.6mm x 22.5mm. A close visual match is not enough on its own, because push button switches can differ in mounting shape, depth, and terminal arrangement even when they appear similar in photos.

This switch is rated to 12V and 3A, so it is intended for a low-current control circuit rather than heavier loads. Where a lightbar or accessory draws more than 3A through the switch, proper relay control is normally the safer approach, but the switch itself should still be matched to the vehicle’s wiring and intended control method.

The supplied wiring colours are Black for earth, Blue for dash light circuit if used, Red for 12V input, and Green for 12V output. When fitting, verify each wire function against the vehicle and accessory wiring before final connection, especially if the dash illumination circuit is being used as an optional feature.

Application references include Isuzu D Max 2009-2012, Holden Colorado 2008-2012, and Holden Rodeo 2003-2008. Those references are helpful, but the correct fit still depends on whether the dash aperture, switch style, and wiring layout correspond with this 38.6mm x 22.5mm OE style push button switch.

If you are replacing an existing switch, compare the face style, mounting size, and terminal setup, not just the vehicle model. The one year warranty applies to the supplied switch, but it does not replace the need to confirm compatibility before 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 TDR11085 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 OE Style Push Button Switch Lightbar, Suits Holden and Isuzu. Part number TDR11085 should be checked first. Listed voltage is 12V. Listed output rating is 3. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TDR11085, 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 switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12V and output 3 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.

Compatibility note: Confirm fitment by checking part number TDR11085, the 38.6mm x 22.5mm mounting size, the 12V 3A rating, and the listed Isuzu or Holden application before purchase.
