If your motorcycle is listed below, the turn signals will blink faster than normal when LED upgrades are installed:

2010 or older Softail Models
2011 or older Dyna Models
2013 or older Sportster Models
2013 or older Touring Models
We offer two options to correct the faster turn signal speed:

The Eagle Equalizer is a small device that automatically corrects the flash rate. It is plug and play, does not produce heat and 1 unit can be used for up to 4 turn signals.

A set of Load Resistors can be used to bring the flash rate down to the stock speed. They are an inexpensive option that will correct the flash rate, but will produce heat and need to be wired into the rear lighting harness.
