Default Re: Faulty Flasher

When I installed LED bulbs in the tail lights of my 2016 Chevy truck the flasher would flash very fast, which is supposed to indicate a burned out bulb. I spent half a day looking for the flasher unit. I finally figured out that the tick-tock noise and flashing lights are generated by a computer and the noise fed to the speakers. I ended up putting resistors in parallel with the LED lights.

I could have just used the bulbs that came with the truck but I wanted the reliability of the LED's.

For those of you changing the flashers, be aware that the pin-outs on different flashers can be different. Compare the pin-out of the one you are taking out with the new one. If necessary, re wire the system.
