What bulb did you use in the cluster that wasn't very bright? What color did you use?

And do you have any pics?

It's ok for now, but I'm planning on making an order to superbright soon for my reverse lights (4crawlers website has a write up) x5's for the dash, a #74 for my controls, and some others for my brother's YJ.
Photo bucket is not cooperating, I can email you some pics if you'd like.

There are three types of vision that are proprotional to the amount of available light in the visible spectrum: Photopic (high light), mesopic (low light), and scotopic (pitch black/very little light). As our human eyes don't have very many rod cells compared with animals, we have a very hard time seeing in mesopic and scotopic boundaries. Instead, we have a high number of cones, which allow the perception of color.

Rods contain a chemical called rhodopsin, which is extremely sensitive to light, particularly that in the shorter wavelength spectrum. The visible spectrum goes from approximately 380nm to 750nm (violet to red). We rely on cones for approximately 450-600nm wavelength, and rods as the bookends of the visible spectrum (most importantly, dark red).

During the mesopic vision stage (driving at night for example), anything of a shorter wavelength such as blue will negatively impact our ability to see because the rhodopsin "resets" and makes the rods MUCH less effective for about 5 minutes. This is called "bleaching" and it can take up to 30 minutes to fully recover from a blast of higher wavelength light.

Conclusion: Because we want to prevent the rhodopsin from the bleaching due to exposure by higher wavelengths of light such as blue and yellow, and because we have so few rod cells compared to cones which are sensitive to those colors, it is best to use red lights for instrumentation. Red lights at the appropriate spectrum will not cause this bleaching effect, or at least keep it to a minimum so that we can see the road.

How is that for an explanation? You can read more here:

No, it shouldn't. I would pull it and check the bulbs just to make sure they didn't blow out or nothing weird happened. As someone posted earlier most LED's are polarized, this means they only work one way. If they don't light up, you just flip them so the contact points power the bulb correctly. Should have no ill effects on other bulbs on different circuits.

Do the hazard light and the A/C button require separate #74s?
