Exactly,the boat we were shooting on last night was rigged correctly with a kill switch for every light bar and submersible.
All the legal lights had their own switch(factory)

We run them on our duck boats - work great.
However, we (or other duck hunters) are usually the only ones out at 4am in 25degree weather so blinding folks isn't a problem. We have a switch that we can reach and turn off IF someone is coming to us.
