In this discussion about lights, I haven't seen any mention about power consumption. I've read a little about the new LED lights coming on the market and they look like they would be worth considering, assuming the price isn't out of reason. For an extended cruise, maintaining battery charge could be critical without a way of recharging. I need to install the entire electrical system on my M17 and I hope to find a way of doing it without being dependent on frequent recharging.
