You'll be fine with all three on at the same time, provided that the additional spotlamp is not drawing current directly from the headlight circuit (wired through a relay and recieving power direct from the battery). However, you'll be using most of the "spare" capacity of the alternator, which is roughly 9A. You'll only really run into trouble if you're riding with all three lamps on and using other power-hungry kit, such as heated clothing, grips etc. all at the same time.

To keep an eye on charging state fit one of these. �12 well spent for peace of mind.
