Interesting...according to this, headlights aren't brighter, they're just misaligned, higher up on vehicles, and of different hues? I mean, I feel all of those are true but I swear some are definitely brighter--maybe some car companies are just skirting the regulations The hue is the biggest reason they feel brighter, I think. Red at 500 lumens feels dimmer than blue at 500 lumens. It's something to do with how each wavelength interacts with the rods and cones in your eyes. LED headlights are by and large "cool" white, versus the warmer white you got with halogens. So I suppose the real solution would be to use warmer LEDs for headlights. --- let's lubricate friction material! ~nickels, Cars & Trucks <cite>Crazyman93 posted [p:979043149] in Those in t...
