I am looking at all the waterproof digital display voltmeters on fleabay. Anyone know which color is the most sunlight readable? The choices are red, green and blue.

Red LEDs are the brightest in daylight and don't hurt night vision after dark.

I just took a red and a blue outside in the sun, powered by a 9V battery. Neither is anything to write home about, but I'd give the nod to the blue, just because the lighted segments blend less into the unlighted segments than the red.

Not sure how much effort you want to invest in it, but I always put a kill-switch on my lighted stuff so that I can shut it off if I want/need to.

Either way though, I'd go with red as well. Blue and green can sometimes be a pain at night, little too bright for me.

Post some pictures when you get done!

Agreed, though I don't think I've ridden at night for 3 or 4 years, and the red can be just as annoying.

Not to be a moron, which probably means I am about to be a moron, why is it that Blue hurts night vision????

Wow, I found that quite an educational read. Thanks for sharing Pat.

I agree with greywolf. As a pilot I'm used to red in the cockpit at night. Or, at least I used to be....haven't flown in a long time due to the expense of flying.

I would suggest that you put whatever color you want on and then rig some type of cover with tint for night riding....just a thought.

Kuryakyn has an LED voltmeter that adjusts intensity for night time riding. It has a really strong adhesive strip on the back that loves sticking to metal or a smooth finish. The wife and I have had them on our other rides for 5+ years with no issues. We mounted ours so they were hidden a bit by the bar center. Bright LEDs at night drive me nuts but this one doesn't at all. I got use to it after a few rides and now its invisible to me unless I purposely glance at it or it's flashing a low volt warning (key on, bike off). It will flash to get your attention when below 12v IIRC. Roughly $30-$40 depending on where you shop.

I'm considering doing the same for my Wee after it arrives next week.
