hyperflash voo-doo
could someone answer this question for me? your car has a flasher and bulbs. if you install led bulbs, theoretically, you aren't drawing as much current through the flasher and it flashes too fast. why do i always see that sometimes you need the load resistor and sometimes you don't, or "sometimes my lights hyperflash but not all the time".
two of the same cars, with the same flasher system and you won't know if your's needs load resistors till you try it.
i can't seem to wrap my brain around this.

I have heard of some members saying they didn't have the hyperflash problem when they installed LEDs, but I sure did when I put the LED Halo taillights on my car. I installed the flasher bypass and not one problem since.

I did not have hyperflash when I changed only my Taillights to LED. I did have it when I changed my front corners as well.
BUT, I could stop it by stepping on the gas just a bit and raising my charging voltage. It only hyperflashed at idle.
It is a sensitive circuit so it isn't surprising. To be honest, it wouldn't have bothered me all that much except my vanity wouldn't allow me to have others see it and think I had a bulb out or that I was just too lazy to correct it.

I have just the led tail lights and no hyperflansh harness. The only time I get hyperflash is when I have the right turn signal on and I brake at the same time. But it doesn't happen all the time! Most of the time it doesn't occur at all. Some times it only hyperflanshes two or three times and quits.

At idle with a fully charged battery you are much less likely to have hyper flash. Usually when stopped and your foot on the brake pedal there is just enough draw on the electrical system to cause hyper flash. At speed it's not normally a problem.
I had it on occasion but always when stopped and foot on the brake. I installed the under dash resistor and have never had it since.

I didn't have hyper flash with my halos but I did with the front switchbacks. I also don't have the resistor with my aca's and they close and lower just fine. Some cars freak out some don't.

These guys are dead on. The computer is very sensitive to voltage output from the battery. On mine I began to have hyper flash on the drivers side with stock system. Then I put LED halos on rear, same problem, added resistors same problem, added LED front corner lights and resistors same problem. Got the hyperflash harness, problem solved! If I did it again I would of gone straight the the harness, the resistors are a waste of time and money!

i also thought the hyperflash harness was a load resistor setup, only in a nice plug and play package. when i installed led's on the harley i simply unplugged a connection under the seat and plugged the load resistor harness in between them. same thing only different? led's were for turnsignals btw

I avoided it when I put in the LED tails by wiring in some slave standard bulbs in behind the rear fascia. They light up but can't be seen.

Oh, I most assuredly stand corrected
Mine did it with just the switchbacks installed on the front, harness fixed it and no problem when later added the halo tails.
I didnt remember people speaking of sometimes on sometimes off with the hyperflash phenomanon.
