Just wondering if anyone following this thread has their Watt Wagons yet or at least is using a Seca 1800 light? Is there a trick to turning it on, is my light defective, or am I overlooking something simple? I've checked the wiring and it seems okay, in fact the little green button on top of the light flashes so it must be getting power and the rear light is working. I turn the light on using the display which turns on the rear light but nothing happens up front. Thanks for any insight.
