What size are those lights? The inverter draw will be proportional to the
load placed on it. Figure 1 Amp/Hour for every ten watts. Watts = volts X
amps. There are some loses in the inverter and as the battery discharges the
inverter will try to run all the way down to 10.5 volts so that is why I use
the 1 to 10 instead of 12 volts.

Thanks Dennis for the info. I only use the inverter to run the 2 lights over
the sink when their is no shore power available. Does this still put that
much load on the alternator?
