    Replaced all my turn signals with led. Now they won't flash. Any idea why?

    You have to use lighter duty flasher, or buy one for LED's at one of the chrome shops, or truck parts stores. They don't pull enough current to make the heavy duty ones flash.

    Do you know where the flasher is at on the truck?

    The standard issue is a thermal flasher (requires load to initiate flash)

    What you need is an electronic flasher (will flash with no load)..

    That would be the clicking sound that isn't there because the lights/flasher are not flashing, right?

    I put the regular bulbs back in when I seen they wouldn't flash. Guess I'll find the flasher first and then swap the LEDs in.
