Of course I vote for red LEDs, although I have read that LEDS can be somewhat "directional". See the "Should I get white lamp switches or LEDs?" on this FAQ.

And while not free ($29), the dimmer I got for my switches is usable on incandescent or LEDs (not at the same time). Being able to control those LEDs could be really nice.

In fact, that particular dimmer even comes with a diode for wiring to a fan, so I may buy two more to replace the high/low switches for the two 12V chrome fans in my bus, making them variable speed...

I sure wish my dashboard had been in good enough shape where just upgrading the lighting could have been an option...

I vote for red too, led's all the way.
Blue is for Bluebirds!

Test the dimmer out on your fans and see if you like it, great idea to have speed control, noise control too.


I think you'll like red lighting. Tried it in my boat but lit the helm a low red glow like Rudolph on his coffee break. Instruments were mostly white but easily readable, maybe even more readable in low light conditions.

You are going to like what you have done, the whole dash rebuild the way it should be done. Very nice work.

Definitely LEDs, but as a trucker, I found blue lights much less tiring on the eyes. As a GI, I found that red lights really burned into the retinas.

I found a video comparing the incandescent bulb to a HD white. My gauges are like these and the face is illuminated instead of being backlit.This might make more of a difference in how color effects how well the gauge can be seen. I may just buy the bulbs to see what looks the best with my gauges.

Yup, you're right about LEDs being more directional, or at least less omnidirectional, than incandescent lamps. When I foolishly put LEDs in my gauges and indicators I got less actual illumination than good ol' incan lamps, even after using the "wide" beam LEDs. My blue Retarder light for the Jake brake now only says Tard when I put the Jakes on. It's a good thing I kept all my original incan lamps, because I'm putting them all back - well over a hundred bucks of LEDs will end up in the trash.

New isn't always better. Look before you leap.

Maybe its my eyes, but I still prefer the warm glow of incandescent.
I filled a closet with bulbs when they were phasing em out.

Has anyone got any idea what happens when an led light is aimed through a prism? I have neither but wonder if it might diffuse the led and help with a wider illumination area.

If so maybe a deflector could be made over the switch panel for a unique affect.


Thanks


John

I'll bet that's not the only "closet filled with light bulbs" at your house...

The VDO LEDs appear to have reflectors/diffusers built into the top of the bulb.
