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

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.

Great for creating a workspace
Color: Grey
I needed a room divider that could be easily folded for storing to put behind my chair during my work calls. This works perfectly! Was very easy to put together. Lightweight but sturdy enough that it won’t fall over.

Base part of it
Color: Black
Even though I kept this it’s very uncomfortable because of the way the base works . They are very long at the bottom and it’s hard to open and close

Great room separator
Color: Black
The panels are much longer than we expected! We only needed 3 of the 4 proivided. It's slightly flimsy, but holds together nicely. The screwdriver that came with did not fit the screws, but luckily we had a Phillips head. It's very lightweight. It is definitely a good value for the money.

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.
