You've got 110 Watts of lighting on order, 15 Watts of heated grips, plus whatever load you decide to plug into the auxilliary socket (GPS? it's about 5W). You need to know your power output and start a list from there. Sorry if i'm teaching granny to suck eggs, but for the Bonneville I run a list as follows:
Alternator 27 amps, approx 300W (working at 12 volts, 12x27 is 324, but if it's cold or the road is slow you'll loose the 24 in no time)
Ignition 30W (guess based on 30A fuse, probably on the safe side but the Bonnie needs it's carb heaters)
Lights 62W continuous (headlight, tail light, sidecar markers), 108 W intermitantly (indicators, horn, brake lights etc.)
Sidecar spot light 55W
Fog lamp 21W
Heated jacket, grips and visor 130W intermittant (on switches)
Adding this up gives 183 W continuous load, so the battery will charge.
The whole lot comes to 365 W, so at that point the battery would start to go flat. I run a 50 ApereHour battery, so with 65 watts used over what's going in, would get about 9 hours fun before it was flat. After say 3 hours at this load the batteries discharge level would limit the number of cold start attempts though.
In other words I can run all the continuous loads I need, but need to take care not to have all the toys switched on all the time. I tend to turn off the heated jacket and grips for as long as I can stand when forced to use the lights and always run the last hour without heat to get some charge into the battery for the next day.
I think you need the numbers for your bike to see just how long you can run those lights for. If you are short, maybe get an LED tail light to save 5W.
