Got these fellas on eBay..
They have a little adjuster thing the lets me adjust the brightness and lets me have the main bits illuminated in blue or green.
The wireing was very fiddley as I wanted to have an absolute minimum of exposed wire/components.
I managed to install the knob just to the left of the steering section of the dash. I ran the wire to the "transformer" up under the plastic panel under the steering wheel - I duck taped the "transfomer" to the back of the shield..(That puppy is going nowhere!) - and did the rest of the wirework behind the centerconsole.
I hooked it all up to the ciggy lighter as his comes on when the lights are turned on - also the ciggy lighter is fused with 15amps rather than 10amp as with most the other electrics in the car.
Apologies for the poor quality of some of the pictures.
