Green Lights on Ebay

Has anyone ordered or tried thoes Green Xenon Lights 9005/9006 that I keep seeing on Ebay?? The bulb is green, but is the light output?? And does anyone think they are brighter than what you are all using?
Any thoughts?

Thank you for the research thread.

A lesson in wavelengths

Basically the longer the wavelength, the further the light can travel. Green = short wavelength = short distance = crappy color for headlights.

So in reality it would be better to use red lights? 700nm of wavelength?
I no tink the cops would like that....lol

Actually yes, red headlights would be the best....but red is reserved for brake lights (so that they can be seen further away incase you need to stop )

Then how come lighthouses aren't red? I thought white was the best color for headlights, as it is all the colors. Red.... red woudln't light up a whole lot. Red is pretty dim on the value scale.

Red, as I said, has the longest wavelength so it can be seen from further away. However the colors of things we see are a direct result of reflecting that color of light (for example, plants are green because their chloroplasts absorb every color except green. So if you were to shine a red light on a blue object, it would be difficult to see that object. White light, as you said, contains all the colors, so you can see everything well. So for the most part, white light is better for both lighthouses and headlights (even though it will not go as far as red) ...but definately not green, which was my point

On a side note, if you notice after red (taillights) and amber (turn signals), then next longest wavelength is yellow. What color are most fog lights? White is not an ideal color for foglights because the fog is made of tiny water molecules, and when white light hits a water molecule or prism, it seperates scattering the light in a million directions.

Actually, fog molecules aren't big enough to scatter white light like a prism. According to this anyway:

Interesting. I replaced my fog bulbs with yellow ones a while ago (not for scientific reasons, just because I got tired of people flashing me when I had them on), and noticed that the yellow ones do not produce as much of a glare against the fog (for lack of better words). I attributed this to the seperation of light in a prism, but I'll take the knowledge of a doctor with evidence over that of my own

It's probably just because it's less light, and the wavelength isn't as harsh to look at with yellow light. So it's perceived less glare... or something. ?
