this is my first tutorial so bare with me the car is a 99 civic ex sedan, i couldnt really find any tutorials with pictures on how to fix the hyperflashing but i knew it was easy to do. i found a writeup on how to modify a stock honda ridgeline flasher by desoldering and soldering some stuff in but this is much easier than that and soldering in load resistors.

i ordered a CF13- JL-02 from superbrightleds.com (the j is for japanese, they also have a cf13 EL which is basically the same but for european cars and two of the pins are different). i read some of the reviews saying these dont fit in the stock box and to use some male and female spade connectors to make an extension harness but i think this is also much easier and you dont really need the plastic box.

basically all you need is a grinder or a file, i used a file at first and realised it would take to long since i had to remove about 3/16th of an inch off the base.the stock flasher relay is 1in x 1in and the cf13 flasher is about 1 3/16 x 1 3/16.

you can see hear the stock flasher fits inside the aftermarket flasher


so to start you remove the flasher relay from the plastic outer box, all i had to do was use my fingernail and pull out on one side of the box while pulling up on one of the pins.

so in this picture it shows the pinout, load is the center bottom, E is the left and B is on the right (exactly the same as stock). also the green lines are the two edges i trimmed to make this fit in the stock location.


final fit



so just so everyone knows this does have the turn signal noise ( some dont and i wanted it like stock) and this flashes at 90 times a second and i think stock is 80 times a second, the hyperflashing was like 120 times a second which got old real quick. oh and i guess when a bulb burns out it functions like stock and hyperflashes to tell you that you have a bulb out.

Looks just like mine! ( no box on it)

Found mine cheap at autozone and only have to remove the plastic case to make it fit. Definitely better than super fast flash

Yes if the specs for stock are correct then this flashes 10 flashes more a minute, you will not notice it at all

Im so confused though. so, it still flashes like stock? whats the point? also, would it work the same if you have jdm side markers wired in?

The point is when you add led turn signals the stock flasher relay thinks you have a burnt out bulb and doubles the flash rate (has to have a minimum load on the relay or it hyper flashes to tell you a bulb is burnt out). When you add led you are cutting back the voltage needed to run them so the relay doubles it's blink rate, this aftermarket flasher is made for led lights so it functions like normal (still makes clicking noise and very close to stock blink rate also still hyper flashes like stock if you lose a bulb)

Not all LED bulbs need these thou. We install LED bulbs at my shop and they have load resistors built into them.

thats good to know, even then maybe someone hates the clicking noises and wants an aftermarket flasher without the clicking so this would help with that also
