100 watt driving lights

I would like to add 2, 100 watt, driving lights, such as Hella, KC, etc. to my truck, a stock 96 Ford F-150. I live in Alaska and during the dark winter months need extra light to spot moose on the sides of the road to avoid colliding with them. My question is, will my stock alternator/battery system handle the extra drain from those lights in addition to my high beams? Both are in excellent shape, but original equipment.

Shouldn't see any problems there they'd only draw 15-20 amps.WOW Sight and Sound

Do it right the first time or don't do it at all.

Hey thanks! I currently have two lights, 55 watts each, that just don't quite give me the light I need. I hardwired them into the high beams. This weekend I plan to put an in-line fuse on both sides, just for safety sake, and will use the same set-up with the higher power lights.

Make sure to use relays for power sorce as high beam circuit won't support the extra currentWOW Sight and Sound

Thanks for the advice mad550, will do. Sure don't want to have an electric meltdown at -25 degrees and be stuck on the side of the road wearing my survival gear!!!
