Universal CF18 LM449 LED Turn Signal Flasher (DIODD4003)

Hyperflashing is a persistent frustration when upgrading incandescent turn signals to LEDs, caused by the vehicle sensing a lower electrical load and assuming a bulb has failed. The CF18 LM449 LED Turn Signal Flasher solves this problem by providing a consistent, electronically timed pulse that remains stable regardless of the bulb type. By replacing the factory flasher module entirely, you eliminate the need for installing heat-generating load resistors, ensuring a clean and reliable blink rate that maintains the professional look of your lighting upgrade.

Features

• Hyperflash Correction: Specifically engineered to recognize the lower resistance of LED bulbs, this module prevents rapid-fire blinking and restores standard signal timing.
• Direct Replacement Design: This unit is a true plug and play replacement for the factory CF18 or LM449 module, fitting directly into the original socket with no tools required.
• Load Independent Timing: Unlike thermal flashers that rely on heat and resistance, this electronic module maintains a steady flash rate even when mixing LED and incandescent bulbs.
• Solid State Reliability: Built with high quality internal components designed to withstand automotive temperature extremes while providing a much longer service life than mechanical units.
• Audible Feedback: Engineered to maintain the familiar clicking sound of the factory turn signals, ensuring the driver is alerted when the signals or hazard lights are active.
