What are the differences between the Gen I and Gen II CANsmart devices?

The main difference between the two devices are the output circuits. The Gen II devices offers 4x 10A outputs instead of the 2x 10A and 2x 4A on the Gen I, so you can connect higher output accessories to the device.

The other difference is support for two sets of individually operated lights. This allows users to change the intensity of each pair lights individually, or even turn a pair off or on while on the move.
