CANbus LED Load Resistors 2-Pack – Fix Turn Signal Hyper-Flash

Eliminate annoying hyper-flash and error warnings when upgrading your vehicle's turn signals, license plate lamps, or welcome lights to LED bulbs. These CANbus LED Load Resistors (2 sets) act as a decoder between your car's onboard computer and the new LED bulbs, tricking the system into reading the correct resistance — so your lights behave exactly as the factory intended.

Available in multiple wattage and resistance combinations (10W / 25W / 50W and 6Ω / 8Ω / 25Ω / 39Ω), these resistors are universally compatible with most 12V vehicle electrical systems, making them a versatile fix for a wide range of cars, trucks, and SUVs.

Key Features

• High Power, Compact Size: Delivers the wattage needed to satisfy your car's load detection without taking up space.
• High Precision & Voltage Tolerance: Engineered to tight tolerances for stable, consistent performance.
• Waterproof Design: Sealed aluminum housing resists moisture and road debris for long-lasting durability.
• Excellent Heat Dissipation: Ribbed aluminum casing efficiently disperses heat, protecting surrounding components.
• Universal Compatibility: Works with turn signals, license plate lamps, daytime running lights (DRL), and welcome/puddle lights.
• Plug-and-Play: Simple wiring connection — no special tools or expertise required.

Frequently Asked Questions

Q: What does a CANbus load resistor do for LED turn signals?

A: When you replace factory incandescent bulbs with LEDs, your vehicle's onboard computer may detect the lower resistance as a burnt-out bulb, causing hyper-flash (rapid blinking) or a dashboard warning light. A CANbus load resistor adds the correct electrical load back into the circuit, so the computer registers the LED as a normal functioning bulb — eliminating hyper-flash and error codes.

Q: How do I choose the right wattage and resistance (ohm) value?

A: The correct value depends on your specific vehicle and LED bulb combination. As a general guide: 6Ω or 8Ω resistors are typically paired with higher-wattage LEDs, while 25Ω or 39Ω are suited for lower-wattage setups. If unsure, consult your vehicle's owner manual or check the LED bulb's specifications for the recommended load resistor pairing.

Q: Are these resistors difficult to install?

A: No — installation is straightforward. The resistor is wired in parallel across the LED bulb's positive and negative terminals. Most installers use basic wire connectors or T-tap connectors. The compact aluminum housing can be zip-tied or mounted near the light assembly for a clean finish.

Q: Will these get hot during use?

A: Load resistors do generate heat during normal operation, which is why these units feature a ribbed aluminum housing designed for efficient heat dissipation. Always mount them on a metal surface (never on plastic or rubber) and ensure adequate airflow around the unit to manage heat safely.

Q: How many resistors come in the package?

A: Each order includes 2 complete sets of CANbus load resistors — enough to fix both sides of a turn signal circuit (e.g., both left and right rear turn signals).
