One.
Should the temp control knob have any light?
Mine is pitch black, coincident with the odd behaviour of my heater controls.
Two.
I also am lucky enough to have an Audi A6, which, whilst driving at night, emits a pale red glow to the interior from tiny little Leds in the head lining. Very nice, as it matches the dial colour.
I want to achieve the same effect in the Supra but with green lights. I rigged up four little 12V Leds behind the rear view mirror but they don't spread any light at all, unless I hold my hand up to them.
Does anyone of you electircal bods know the ref.code(say, from Maplins or similar) for a green Led that will actually project a pool of green light?
