So are the Spikes "just" a straight relay with the coil powered completely from the digital sidecar? Or, are they using the voltage from the input side along with a signal from the sidecar to drive the coil.

The reason I ask - is *if* the coil is powered completely by the side car, then I would think we could wire the 6V from the sidecar's servo control thru a spike that is controlled from the relay control of the sidecar and use the output from the spike to the flashlight.

Everything I have found for the spike relay's shows them wired to 12V, but a straight up relay wouldn't care what that voltage is. I haven't found a circuit diagram of the guts of a spike.
