Diode Dynamics DD4025 LED Load Resistor Kit 50W 6-Ohm - Universal Turn Signal Hyperflash Fix (Pair)
SKU: dioDD4025
Overview
The Diode Dynamics DD4025 LED Load Resistor Kit (Pair) is the trusted, American-made solution for eliminating turn signal hyperflashing after upgrading to LED bulbs. Engineered for any 12V vehicle with incandescent-based turn signal circuits, this kit restores normal blink speed without cutting into your factory wiring harness. If you're searching for the best LED resistor kit to fix hyperflashing on your car, truck, or SUV, this is the go-to choice from the industry leader in automotive LED lighting.
Key Features & Benefits
- Eliminates Hyperblinking / Hyperflashing — When you upgrade to LED turn signals, your vehicle's flasher circuit senses the reduced power draw and incorrectly interprets it as a burnt-out bulb, causing rapid hyperblinking. This resistor kit reintroduces the correct load to the circuit, restoring a normal blink rate instantly.
- 50W / 6-Ohm Rating — Each resistor is rated at 50 watts and 6 ohms, replicating the power draw of a standard incandescent turn signal bulb for full compatibility with your vehicle's factory flasher system.
- 6" Wire Leads for Easy Installation — Extra-length leads allow you to reach the turn signal wiring without splicing directly at tight connector locations, making installation clean and accessible.
- Includes All Hardware — Everything you need for two turn signal positions is in the box: 2 resistors and 4 quick-splice scotch-lock connectors. No additional hardware, soldering, or special tools required.
- Universal Fit — Works on Any Vehicle — This is a non-application-specific product compatible with any 12V vehicle that uses incandescent-based turn signal circuits, from daily drivers to trucks, Jeeps, and performance cars.
- Made in the USA by Diode Dynamics — Engineered and assembled in St. Louis, Missouri, these resistors meet strict quality standards, unlike generic offshore alternatives that may fail prematurely.
- 3-Year Worry-Free Warranty — Backed by Diode Dynamics' industry-leading no-hassle warranty. If any defect occurs, they troubleshoot and replace — no lengthy return-and-repair process needed.
- CARB Compliant — This product meets California Air Resources Board (CARB) compliance requirements, making it legal for use in California and all 50 states.
What's Included
- 2x LED Load Resistors (50W, 6-Ohm)

Fitment & Compatibility
This is a universal fit product compatible with virtually any 12V car, truck, SUV, or Jeep that uses incandescent-based turn signal circuits. One resistor is required per LED turn signal bulb replaced. If upgrading only front or only rear turn signals (2 bulbs), this pair kit is the correct quantity. If upgrading all four turn signals (front and rear), two pair kits (or the DD4025Q set of four) are recommended. Note: This product is designed for vehicles with factory incandescent turn signals. Vehicles with factory-installed LED turn signals (such as certain Dodge/RAM models) require a different hyperblink fix module.
Frequently Asked Question — Do I need one or two resistors per corner? One resistor is needed per turn signal bulb position switched to LED (one per corner). For a full vehicle conversion (front left, front right, rear left, rear right), four resistors total are required.
Is this CARB compliant? Yes. This product is California Air Resources Board (CARB) compliant and is legal for sale and use in all 50 states including California.
Installation
Installation is a simple DIY process requiring no prior electrical experience. Connect one side of the resistor to the positive turn signal wire and the other side to the negative (ground) using the included scotch-lock connectors — no soldering required. For dual-filament sockets, use a voltmeter to identify the correct power wire by engaging the turn signal and probing the socket pins. Important Safety Note: Resistors will become hot to the touch during normal operation. Mount resistors away from plastic, wiring looms, foam, or fabric to prevent heat damage. Professional installation is not required, but take care when selecting a mounting location.
