Glow fuses

[WokingWedger]

Anyone tried these?

Are they any good?

I undersatnd they glow when they have blown, so they must have a second
'by pass ' circuit that powers the filiment or LED. Not sure how this works ?

Ian,

Is the glow obvious or is it hard to see ?

Do you know how they work ?

Thanks Leigh, so for example if your heater blower dosnt work, but is switched on and you look at the fuse and its lit up then the fuse has blown.

Are the LEDs bright ?
