I’ve got an array of Custom Dynamics lighting on my 21 TriGlide and 17 FlHXS. Recently the Trike threw some codes and shut down all lights except headlight and brake lights. Diag revealed Bcm was shutting down as something was overloading . It turned out it was the pass through harness for my vent light ( with the module built in) on one side . One call to Custom Dynamics with an explanation of issue and one call to get process and get part shipped and then a few minutes to plug a new one in once it was delivered , free of charge, and all lights are up and running again. Kudos to Custom Dynamics for lifetime warranty and actually living up to their promise!
