The Diode Dynamics LED Resistor Kit (Pair) DD4025 is engineered to eliminate hyperblinking and "bulb out" error codes common when upgrading incandescent turn signal bulbs to LEDs. Because LED bulbs draw significantly less current, most vehicle flasher relays or CAN-bus modules assume a bulb has failed; these load resistors mimic the factory power draw to restore normal flash rates.

Built for long-term reliability, these resistors dissipate heat efficiently and are compatible with any 12V automotive lighting system. The kit includes all necessary components for a clean installation into your existing wiring harness.

• Corrects Hyperblinking: Restores the factory flash speed for turn signals after LED installation.
• Universal Application: Works with all 12V LED bulb upgrades that require additional load.
• Complete Kit: Includes two resistors and T-tap connectors for a secure electrical connection.
• Manufacturer Part Number: DD4025
• Warranty: Protected by a 3-year replacement warranty.

Note: Resistors generate heat during operation. For safety, mount them to a metal surface away from plastic components or other wiring.
