48-50 F1 headlight switch glass fuse help 6v

[Cody_1948]

Hi Guys, I have a aftermarket headlight switch (older style) in my truck which is still 6v I have newer wiring kit I updated the truck with. I'm having hard time trying to find what amp fuse to use with the switch with the 6v system. The headlight switch is the only glass fuse I see in the whole truck. Been told glass fuses where never used in these trucks.

Any help would be great.

Thxs a million
