    I had a look at my suppliers, and found this in Amazon(!). Any good? "DIGITEN waterproof in Line standard Blade Fuse Holder fuses+10A 10Amp kit car boat bike".
    Good luck with your testing!

    I had an email from 'Haverlock' making the point that 'my' formula is no good for motors, etc. I agree. I did state it was for LED supply resistors. I found several references to this formula among which were 'Sparkfun' and the book "Introduction to Analogue Electronics". Any dissenters should take it up with RS - that's where I found it about 40 years ago. Case closed.

    Hello, try looking for old 25way data cables at your local car boot sale. The cores are multi-coloured and very thin. Most LEDs only use a breath of current to drive them so you won't start a fire! Here's a tip about dropper resistors for LEDs: put them at the power supply end where you can tie them down securely. Also, the formula for finding the resistance you need is: R equals Volts(supply) minus Volts needed by LED (Vf) divided by the required LED current (If). So, say 12V supply, 2V LED wanting 15mA = 12-2=10/.015 = 666.667, so you'd use the nearest value above, which would be 680ohms. Easy! The size of the resistor in watts/milliwatts is found by I(current) times E(volts), so 10X.015=.15W, or 150mW. Hope I'm not teaching an old sea dog new tricks!

    Hi chaps, just for info, 'Bright Components' do 6 different colours of flashing LEDs very reasonably priced. Also flickering - very interesting.πŸ˜‰
