DC, Please refresh my memory...are these 12V only or are they variable 12-24V?
These lights come with a 50W, 12V bulb which is too power-hungry for most biking applications, so you're going to want to change the bulb anyway. They take a MR16 bulb which is most common in 12V, but is also available in 24V (and sporadically in 6V). It's not really "variable" in the sense that you can run the same light off of different voltages, you pretty much have to run the bulb at its specified voltage.
