Will a Rupp Roadster 2 switch handle a 12 volt 45 watt LED headlamp amperage ?

I bought a new reproduction Rupp switch from Blackwidowmotorsports and I have a 30 watt low beam 45 watt high beam Daymaker LED clone that I bought from Amazon. According to a calculation the max amp that a 45 watt bulb would draw at 12 volts is 3.75 amps. Will the Rupp Roadster 2 factory style switch be able to handle that current of 3.75 amps? I am using 18 guage wire which can safely handle more than 10 amps of current so the wire should be fine with this headlight.

I seen that a factory Rupp roadster 2 incandescent headlight is rated at 40 watts. So the extra 5 watts should be ok I believe. Plus I bought the led taillight brake light which will use only 3.3 watts vrs 15 watts of the incandescent tail brake light so the over all wattage is actually 6.7 watts less. 55 watts incandescent vrs 48.3 watts for LED headlight taillight combination
