Glass Fuse Question

So my turn signal fuse went out. The box calls for a 5x20mm, 15a/32v so I head to AAP and none, head to Autozone and none, head to Amazon and mostly none...with the exception of resellers selling what appear to be old stock...really old stock.

There's plenty of 15a/250 volt in 5x20mm, but from what I know (not much), that voltage doesn't work.

Are these fuses really unicorns? Are there any modern workarounds for a lack of fuse supply?

I kept a bunch. Even a 50 year old unused fuse is as good as new. Old stock is fine, but my Advance store still sells them new.

Volts don't blow fuses ... it is Amps that blow fuses. Amps represent a quantity ... volts represent a quality. I can start an arc with just 12 volts, I can maintain it and weld steel with 90 amps using my favorite rod.

Those 5x20mm15A@250V fuses will work perfectly. They are rated to prevent voltages of up to 250 from leaking by arcs, etc.

I would stick some tin foil or something in it's holder and see if anything is wrong before risking a good fuse.

Yes voltage spec doesn't matter on these as long as the rating is equal to or greater than the application.
