Description
12V LED Load Resistor Twin Pack Prevents Dashboard Errors, 21W Equivalent Draw
Product Overview
The LED Autolamps LR12/2 is a twin pack of 12V load resistors designed to prevent dashboard warning errors when LED lamps are fitted to vehicles that expect the higher current draw of a standard 21W incandescent globe. By drawing the same current as a 21W globe, the LR12/2 tricks the vehicle's electrical system into recognising a correctly loaded circuit eliminating false globe failure warnings.
Must be mounted to a metal surface for heat dissipation. IP67 rated and backed by a 5-year warranty.
Features & Benefits
-
Prevents dashboard errors — eliminates false globe failure warnings that occur when low-draw LED lamps are fitted to vehicles with CANbus or load-sensing electrical systems
-
Draws same current as a 21W globe — mimics the load of a standard incandescent indicator globe so the vehicle's system registers a normal circuit
-
Twin pack — two resistors supplied; typically one is required per lamp circuit
-
IP67 rated — fully sealed against dust and water immersion; suitable for exposed vehicle body mounting
-
Must be mounted to metal surface — heat generated by the resistor requires a metal mounting surface for safe dissipation; do not mount to plastic or timber
-
12V only — designed for 12V vehicle electrical systems
-
5-year warranty — backed by LED Autolamps' full warranty programme

Frequently Asked Questions
What is a load resistor and why do I need one?
Modern vehicles use CANbus or load-sensing systems to detect globe failures. LED lamps draw far less current than incandescent globes, so the system registers the circuit as a failed globe and triggers a dashboard warning. A load resistor adds resistance to the circuit to mimic the draw of a standard 21W globe, eliminating the false error.
Does the LR12/2 work with any LED lamp?
The LR12/2 is rated to draw the same current as a 21W globe, making it compatible with LED lamps replacing standard 21W indicator or stop/tail globes. For other wattage applications, confirm compatibility with F.A.E. or LED Autolamps.
Why must the load resistor be mounted to a metal surface?
Load resistors generate significant heat in operation. Mounting to a metal surface allows this heat to dissipate safely. Mounting to plastic, rubber, or timber risks heat damage to the surrounding material and potential failure of the resistor.
What is the IP rating on the LR12/2?
The LR12/2 is rated IP67, meaning it is fully sealed against dust and water immersion — suitable for mounting in exposed locations on the vehicle body.
What warranty does the LR12/2 carry?
The LR12/2 is backed by a 5-year warranty from LED Autolamps.
