This is a replacement turn signal flasher module that has been designed for use with LEDs. It will eliminate fast turn signal blinking, known as hyperblinking. This module is 100% plug-and-play, for easy installation in select Honda and Acura vehicles. Just unplug your factory flasher module, and replace it with this one.

This module will blink at the standard speed with any combination of standard or LED bulbs. You can use it with front LED bulbs, rear LED bulbs, or even with both front and rear LEDs! It will only hyperflash if there is nothing connected to both the front and rear turn signal sockets.


Why do you need this module? When your factory turn signal bulbs go out, your vehicle's flasher senses that less power is being used, and it will blink the turn signals quickly to alert you. When LED turn signal bulbs are installed, it lowers the load on the circuit too, because LEDs use less power. You get the fast blinking, known as "hyperblinking," even though the LEDs are functioning just fine. Basically, your car thinks the bulbs went out!

To slow down the blinking, you can add resistors to increase the circuit's power consumption again. However, whenever possible, replacing the flasher with a module like this is the easiest option. This is the unit that actually controls the blinking speed, and makes the "clicking" noise.

  1. As if the car were built for LEDs Review by Chris

    A little pricey compared to what a DIY could do, but I wanted something quick and easy that was guaranteed to work and this did just that. The when using the turn signals or hazards, the initial "blink" when using this is slightly longer than the other blinks, which DiodeDynamics has assured me this is normal. Overall, I love it because it allowed me to adapt my car to the benefits of modern LEDs with no one being the wiser. (Posted on 8/2/17)

  2. No Need For Resistors!! Review by Henry

    Installed this flasher module into my brother's 2006 TSX, along with rear red turn signal LEDs (XP80) and front yellow turn signal LEDs (XP80).

    The flasher works as described. No hyperflashing, and no need to cut into the wiring and add resistors. The flasher is just slightly faster than the stock one but by no means is it close to the hyperflashing. Plus it still has the ticking sound so you know the turn signals are on and working.

    Installation was pretty easy. You just have to lie on your back and look up into the fusebox beneath the dashboard. The stock flasher module is grey in colour and located at the top of the fusebox. There are two clips you have to push apart in order to remove the old flasher module. It takes some time but rocking the flasher back and forth loosened it enough so that you could pull it out. If you can't see the flasher, turn the hazards on and feel for the ticking the flasher makes. Remove the stock flasher and install the new one in it's place.

    Great alternative to cutting your wires. I wished my SUV had a replaceable flasher.
