Thinking about a dash light upgrade. Your thoughts?

I have used LEDs from Superbrite in a couple of my Darts now and they are much easier on my old eyes at night. They come in different flavors. Replacing these bulbs and getting polarized bulbs in the right way on your back on the floor of the car operating by feel is not something I would recommend - they make non-polarized, dimmable versions and that is what you want.
