I installed 3157 led taillights and the flasher blinks fast. I then put a resistor on the first left blinker and no change. I then put a second resistor on without any change. Anyone have a solution for these?

I think each bulb will need a resistor.
My Eagle Eye LEDs all have one.

That's what it takes. Very

I put one on each bulb without luck. I tried jumping it across each yellow to black without results and then tried just on the yellows to see if that would work and nothing there either. I have heard about changing the flasher but if you do that then why would you need the resistors? My thinking is if power takes the least path of resistance then the resistor should go in-line or it would not do anything but that is notwhat I have seen on YouTube

You didn't get an instruction sheet with the LED's?

Davidmcc

Vendor lately have not included instruction sheets with anything. I have been going to YouTube

EVRose

Did you see this one?


BTW, there is no flasher in a C6.

Radio Flyer has a plug and play setup you might like, plus some great LED's.

That's good to know about the flasher before spending a day looking for it. Thanks

I bought led tail lights as well, each light had a module with a resistor that's 4 of them. Never caused any issues for me

LED's use less power than halogens, when your car realizes there is less power being drawn it assumes the light is burnt, and so it hyperflashes in an effort to notify you that a bulb is burnt.
Resistor uses up more electricity and converts it into heat and wastes it to trick the computer into thinking there are still Halogens by pulling the same voltage of a halogen.

Thank you for an excellent explanation!

Every LED needs a resistor across it (not in series) so that the BCM computer sees the same CURRENT (not voltage) as the factory installed bulb. The LED DOES need a resistor in series to limit the current through the LED but that resistor is built into any LED that is rated for a voltage above about 1.5 volts.

BTW, it is the BCM that does all the flashing as well as a few hundred other things. No flasher and no manual timing advance on these new fangled cars.

Check out the video as a guide.

I got the hyper flash taken care of but now the issue is the running lights are brighter then the turn signal, could it just be bad lights?

robertmc1958@gmail.c

Well actually there is, it's incorporated in the hazard switch.

Maybe you have reversed the wires?

EVRose

Well actually, you're wrong. The BCM controls the flashing.

Davidmcc

The bulb only works when installed one way. When you spin it neither light works. The wires weren't changed. If I do not hear of a solution, I will try some other bulbs.
thanks

I have heard that there is a slight variation in design for the outer tails and the inner tails. And switching them upon reinstallation can cause brightness issues.

I haven't run into this or tested it, but are you sure you have the outer in the outside spot and the inner in the inside spot?
