that the LEDs shine brightest at 20mA, so having a 6V power supply from my wife's sewing machine I bought 300 Ohms resistors an soldered them to each diode. I choose the longer leg to fit them to, but it doesn't really matter where you put them.
I also made a little "power distribution" stripes, so I can add some more LEDs in the future more easily, if I'd need to.
Another test, this time connected to power supply:
...and it's working perfectly.
Last thing to do was to get a few screws to put all of that together with my hood:
...and finally I can enjoy the fruits of my hard-work:
LEDs - pack of 50 from e-Bay: £1.60
Resistors - electronics components store: £3.60. I could have them for about £2 (e-Bay!) but was growing impatient
Power supply came earlier with my wife's sewing machine, and is still usable if needed - I remade a spare plug that came with it so it can be disconnected at any time.
Bit of a time and sweat...
I hope you enjoyed reading about it as much as I enjoyed making it
