Just saw a thing on the telly about fuses with a little LED in them that lights up when they blow.

Pretty neat, but I bet they are expensive !!

That'd be nice, but not worth the extra $ IMO. There are only so many fuses, it's not hard to figure out which one is blown based on what problem you're having.

Nice idea -- I've seen them in the higher end car stereo shops.

If they burned out once or twice per year I could see the value. But I've replaced maybe 2 fuses in the last 10 years -- not something I run into all that much.

you can DIY too. its pretty easy.

step
1) Get an LED
2) Get a resistor (1k should be good)
3) Solder a resistor to the cathode (shorter wire coming from the led)
4) Attach (up to you how) the anode (long end) of the LED to the battery side of the fuse (or wire leading to fuse)
5) Attach the other end of the resistor to the opposite end of the fuse (or wire leading to fuse).
6) Have a beer, your done.

TIP: You can use surface mount (0805 is a good size) components and epoxy them to the top of the fuse for a clean look.

note: This (and the ones you buy) only work if the fused device is trying to draw current.

Total cost: about 20 cents and they are reusable.
