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 ?

I replaced every fuse in my Griffith with these - after spending hours chasing wiring to find a fault, including lifting the centre console, only to discover the fault was one of the fuses I'd already checked.

To my thinking it was worth the money never to have to do that again, but to be able to stick my head in the footwell and see a fuse has gone at a glance has to be worth the money.
I got together with a group of Griffith owners and we figured out how many we needed for the different variations and with a combination of importing some from the USA and buying some from Maplin got them down to a sensible price which made it all a no brainer anyway.

Ian,

Is the glow obvious or is it hard to see ?

Do you know how they work ?

WIth the ignition on they flash so easy to see. No idea how they work as not technical.
Ian - have you go the link to the guy in the US as I need some for the Wedge, email off line please.

Hi Paul

You can find glow fuse packs for most TVR models here: www.tvrextras.co.uk

Hi Paul,

I got my wedge one's from Steve Heath,

And they do work well, I've blown 2 now. 2nd time was my fault due to experimenting.

The ones I have only light up when your driving what need to be driven, if that makes sense.

i.e. if you blow the lights fuse, it will only light up when you put the lights on.

They work by having the LED across the terminal, due the fuse being a short the voltage will not pass via the led and electricity will go the path of least resistance.

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 ?

Is this correct? Doesn't that negate their value for certain replacements then? I'm thinking that I can't stretch my neck to the boot in the Cerb, while pressing X button...

No different to the normal case where you need someone else to press the button while you probe the fuses individually or remove them and visually inspect them. The advantage is that you can see exactly which one has gone without all the hassle or knowing the fuse layout.

Yes. You can see them in daylight. I had a demo box showing them light up at some of the shows and it was very easy to see. Even easier down in the depths of the footwell
