They have a 5A inline fuse, and I don't think the wattage was actually all that high.
I'm using the switched pair in the headlight cowl. Seems to work fine powering my heated grips. No fuse problems or any other probs in 5 years.
Thin rubber grips are the way to ... thick ones insulate too well and block heat transfer. I can feel mine down to about 20F ... below that you hardly know they are on. I'm using the Dual Star heaters. Not bad.
If you look around you may find Snow Mobile grips with higher output ... but be careful not to MELT your throttle tube ... or switch to a metal throttle tube.
