Works good
The only problem is on my bike (2008 Road King Classic), the connector that plugs into the bulb has two releases on it. The Signal Dynamics Module doesn't have this, and there was about a 1/6" of the electrical spade connectors still showing after connecting together. I just ty-wrapped the two connectors so they couldn't work loose, and wrapped it with electrical tape to help seal everything.
