adding 2 gauges

an electrical temperature gauge and a voltmeter - am planning to run a hot wire from battery to these 2 gauges with an in-line toggle on switch and a fuse. If I don't care about shutting off or dimming the gauge lights when running, would I able to simply use this same source to power the gauge illumination lamps? thanks
BTW bulbs are .19 A and I'm thinking gauges should not draw much- 5A fuse should be enough..? thinking out loud here
