Default fuses on headlight switch?

What are the fuse sizes on the back side of the switch?

The fuses are SFE-7.5 for the interior dome light and 1AG-5 for the turn signals.

Well.... here's an interesting discovery:

My shop manual for my '58 says the headlight switch only has one fuse on the back (the dome light fuse). It also states that for the turn signals, the '58 should have an in-line cartridge-style fuse holder with a 7.5 amp fuse inside.

However... my headlight switch must be from a '60 because there are TWO fuses on the back of it. The dome light fuse was the proper 7.5 amp fuse. The turn signal fuse had a 20 amp fuse in it...tracing the wire to the flasher pod....I found a cartridge fuse holder that had a 7.5A fuse in it.

Now here's the question:
What to do now for my turn signal circuit?
1. Put a 7.5 amp fuse in BOTH locations?
2. Put a 5 amp fuse in the headlight switch and just remove the cartridge fuse altogether?

I DO know that the 20 amp fuse will NOT be re-installed.

What are all fuses designed to protect? The answer is most obvious, but most people get it wrong. That's why you see huge fuses in circuits where they don't belong.

If you have two fuses on the same circuit, it really doesn't matter how big one of them is as long as the other one is the correct size. The 5 amp fuse will blow first just like if the 20 amp fuse wasn't there and the circuit was wired straight to the 5 amp fuse.

My '58's Shop Manual says the current draw on the turn signal circuit is "0-4 amperes". So I'm going with the 5 amp fuse at the back of the headlight switch, and splicing out that goofy little cartridge fuse holder.
