That is only if you put on the 4 way flashers while towing a trailer. Those bulbs draw just over 1 amp a piece, I'm not sure what the flasher unit draws but being solid state my guess is it's negligible. The fuse will protect your signal controller as well as the flasher. Both are somewhat expensive, and both are likely going to be in US dollars when you do order one.

Im not a "wise man", but I Installed a 5 amp fuse in my system per this same advice several months ago here: http://www.mapleleafup.net/forums/sh...use#post240252 See posts 62, 63 & 71.
