What amperage fuse???

[Mercougar67]

Hey guys, i somehow blew the fuse for the instrument lighting for my 69 firebird (which im guessing is the same as a 69 camaro). On the side of the fuse box under the dash it has the amerage for all of the fuses. The one on the bottom that says "inst lps" and is supposed to have the amperage on the left side where the fuse goes. Mine has somehow worn off and i dont want to put too big of a fuse in there. Could someone take a look at theres and see what amperage it needs... thanks in advance...
