Not sure if I need one or not. I run Gerbing jacket liner and gloves which use 100-105 watts. I don't use anything else such as GPS etc. Might get heated socks which would push watts to about 130. I know from reading here that my 2011 has about 140 usable watts. Question, if getting cutout which one high or low beam. Doesn't it just turn off the whole right or left side. Probably a dumb question but me and electrics Going to order the left side socket plug so would order cutout at the same time.
