Works great fixed my turn signals from being solid
Saved my ass by providing turn signals, essential for SAFE riding at night. Impressed with build quality. Getting used to operation but appreciated !
Going to take some time to get used to holding signal button 1-3 seconds every time you turn them on.
I purchased this 1998 Harley Softail Custom and someone had removed the rear turn signals to install fiberglass saddle bags. So it had no rear turn signals on it so I ordered a set to go on the back of the saddle bags and wired them all up and then no flash what so ever. I tried multiple things and wasn’t getting anything so I asked a local Harley shop and the owner told me to order a new module from Custom Dynamics!! Couldn’t be happier it plugged right in and worked instantly. If I ever need another one this is where I will be ordering it!!
QuicK easy change out. No need for additional load equalizer when installing the custom dynamic module. Great product! Very satisfied.
