I recently have switched most of my interior and exterior lighting to LED. Currently my turn signals are switching between Hyperblinking and normal blinking. Sometimes it switches back and fourth or does one or the other during the time I have my turning signals on.

I added LED Load Resistors to both turn signals on the rear. It made it so the turn signals were constantly and always Hyperblinking. (Making the situation worse).

Has anyone else had this problem? If so, what did you do to fix it? Do I need resistors on all four of my turn signals?

Thanks for any help and advice!

 

Yes, you need a load resistor for every bulb.

 

the LEDs use almost no power, so the vehicle thinks the bulb is blown and will fast flash.

You will need resistors on any you replaced with LED.

Resistors are measured in ohms.

Old fashioned stupid light bulbs are measured in watts.
Not how much light they make, but how much power they suck... because... old people?

So what you need is to figure out how many ohms = watts of bulb you replaced on your system.

Watts/Volts/Amps/Ohms conversion calculator
a 35 watt bulb at 14v is 5.6 ohms. 35 watts at 12v is 4.1 ohms.

so... you'll need somewhere around a 4-6 ohm resistor. I think I had to use 6 on the back on mine. 4 ohm didn't fix it. but it was 6 years ago... so.. maybe it was 6 ohm?

I suggest you do ONE light at a time until you get this right. else you'll be unable to tell which light is causing the issue...
