Are you running straight off the wiring for the lights, or through a relay?
I don't know what the wiring for the light is, but I would be a little apprehensive to run heated grips direct off the wire for the headlight. I guess head light circuits will have around 4 to 5 amps in the circuit and by adding the heated grips another 4 to 5 amps or so. I doubt Mr Yamaha put wiring large enough for double the design current rating (being tight and all that, use the minimum + a little bit) and you could fry the wiring.
Also, running fromthe battery (through a relay) will have less loss of voltage so the grips will (I think) work better at tickover.
