12V 25W CanBus Resistor

Specifications

Output	25W
Input Voltage	12V

Product information

This 25W 12V CAN-bus resistor fixes dashboard fault codes and flickering or fast-flashing indicators that can appear when a vehicle’s onboard electronics detect the lower current draw of an LED bulb compared to the original halogen unit.

Wire it in parallel across the + and – of the affected circuit — commonly an indicator or tail light circuit — to simulate the original bulb’s load, and the fault clears without any changes to the vehicle’s wiring loom.

Dimensions and installation

Voltage: 12V only
Output: 25W

Tip: connect the resistor in parallel with the affected LED circuit, not in series — wiring it in series will stop the light from working at all.

Compatibility

This resistor works on any 12V circuit showing a fault code, flicker or hyper-flash after an LED bulb swap, regardless of tractor brand.

If you’re unsure whether your fault is a good match for this resistor, contact us before ordering.

Also suitable for other machines?

Yes — it isn’t tied to a specific brand or model, so it works on any 12V circuit exhibiting this fault. Contact us if you’re not sure it applies to your situation.

Why matching the original load matters

Simulating the halogen draw:
Onboard electronics monitor current draw to detect a blown bulb. An LED bulb draws far less current than the halogen unit it replaced, which some systems misread as a fault. This resistor adds load back into the circuit so the reading looks normal again.

12V-only rating:
This resistor is rated for 12V systems. Using it on a 24V circuit isn’t the correct match — check your system voltage before wiring it in.

Frequently asked questions

What does this resistor fix?

Dashboard fault codes, flickering, and fast-flashing (hyper-flash) indicators that can appear after fitting LED bulbs on 12V circuits.

How do I wire it in?

In parallel across the + and – of the affected circuit, alongside the LED bulb, not instead of it.

Will this work on a 24V system?

No — this resistor is rated for 12V systems only.

Does this work with tractor headlights like the CRAWER CR-3009?

No — for CRAWER’s Hyperios headlights (CR-3007, CR-3008, CR-3009) use the dedicated CR-RES02 resistor, which has the matching 2-pin Superseal connector.
