Hello Al,

Not sure which formula you are using to calculate the current draw, however;
the correct formula is : W (Wattage) = V (Volts) x I (Amperage).

Assuming you have 55 watt headlights (if not just change the number in the
equation) and switch on both auxilliary lights at the same time and
transposing for I gives

I  = 48+48+55+55 / 13.6 which equals  15.15 Amps (206/13.6) which a generator
is capable of producing and well within the limits of an alternator.
