Dashboard lighting. - Yes they are great from the anticipated reliabilty point of view, but don't make the mistake I did.
I bought a Blue led conversion kit for my old Volvo, because dismantling the panel is a *** job. Thought they should last for ever; very fashionable, blue, too.
No-one mentioned that you can't see a red pointer in a blue light when the background is black!
At least I'm getting quicker at dismantling it.
