LED Turn Signal Flashers

Everyone loves upgrading their trucks and trailers to long lasting LED lights, but you can run into problems if your turn signal flasher isn't built to operate with them. The problem is that a standard mechanical flasher operates based on the electrical current flowing through it, and one of the benefits of LED lights is the reduced current required by them. The result is that you have less current running through your flasher, and that current is outside the flasher's prescribed parameters. This can cause the flasher to operate erratically, flashing too fast or too slow.

What you need is an electronic flasher meant for use with LED lights. All of the flashers shown below are up to the task.
