Daytime instrument lighting to help ageing eyes.

I've been having difficulty reading the stuff on the panel in Daisy's tacho during the day when the lights are off, night time though is fine so I thought I'd try a method of lighting it whenever driving.
 Rather than use two diodes I ordered some rectifiers to give things a fancier look, this is a  Schottky one but normal silicon ones should be fine as the extra voltage drop should be fairly meaningless.
All ready to plug in now, the yellow wires are for the Voltage supply, one for the lighting and one for an additional accessorises input I wired in that will come on whenever the key is turned, I used a rectifier as I was quite cautious about what effects it could have on things and this isolates the current.
 This is the plug on Daisy (a Proton FLX S16/Saga) that fits into the instrument dimmer, the Voltage is supplied via the green/white wire on the left here, I cut it and fitted spade connectors to suit. This was the hardest part of the job as there was very little room, and it also explains why I fitted flying wires to the rectifier.
The end result though wasn't what I expected, it only lights when the ignition is on, and also the tacho and speedo binnacles only light when the lights are on, but when I thought about it that's exactly the result I desired as I can now easily read the little panel and it doesn't turn other things into a xmas tree.
