Important Notes Concerning LED Flashers
  • These flashers do not replace all flasher units. Before you order, please see the pin outs of our flashers in the More Info page and compare with the one you are replacing. Click the part numbers for complete specifications. You can usually find your flasher pin out printed right on your flasher. Failure to check this and installation in an incompatible vehicle can blow your fuse, destroy the flasher and void the flasher warranty.
  • Some of these flashers operate silently, they do not make the familiar clicking sound when operating. One solution is to connect a common automotive relay to the output along with your LED bulbs.

its ok

it will mess up your lights on your car.

if you have a 2006 scion tc or later and you keep your lights on after you turn off the car(as they auto shut off when the door is open) and you go to lock or unlock the car. all lights on the outside will blink. headlights tail lights.

but if you turn your lights off it works fine.

Response from Super Bright LEDs:

Thank you for taking the time to send us a review. Customer feedback is very important to us. Sorry that you are having problems with the flasher. When the car is off the CF18-08 has a high resistance in the circuit compared to the stock flasher. So when you leave the light switch on it provides a path of less resistance and causes lights on the headlight circuit to flash. This may be an annoyance but will not harm anything.

It does the job!

Great led flasher. Gives the same blinking rate as the stock flasher. Works great on a 2005 Toyota Sienna. The only thing I could not do was to attach the led flasher where the stock one is located because of its awkward location, but this is Toyota's fault, not the led flasher. I recommend this led flasher to any who wants to turn their turn signals into leds.

Perfect for Prius

This is a perfect solution for my all LED signal lights in my Prius. Keeps the same "blink" rate without modifying the stock wiring to add load resistors.

Beyond easy!

I looke dinto adding load resistors before finding this little gem, took two minutes and now all of my led's function properly. A true time saver! And it will save you money if you use a lot of led's that need resistors.

Like OEM!

I installed this relay to replace the old relay in my 2016 Subaru BRZ Limited, as I was replacing the turn signals with LEDs.

With that, it sounds a little louder (which I prefer) and works just like OEM. It's a great replacement if you need a basic replacement or for LEDs.
