I cant imagine it really takes 100W of LED power for a headlight. too lazy to google......


Even if headlights ran off a mr fusion and took no power they couldent significantly increase MPG in anything resembeling a normal car. Focusing effort on efficency gains with headlight improvments is like trying to drain the ocean with a table spoon.

He's assuming a radar/laser detector. This has been covered elsewhere (in the radar detector thread namely) but I can report as a former V1 user that certain vehicles' tail- and headlights would set off the laser warning reliably. Infiniti FX headlights and Chevy Trailblazer taillights are two I remember in particular.

Why doesn't BMW do what 90% of the idiots on here do and just cram some HIDs into halogen housing? There can't possibly be anything brighter and more annoying than that.

I do like how it goes out when the turn signal is on. Half the time around town it looks like the douchebag is driving a car with broken LEDs.

Glare isn't the same as brightness. Brightness is measured in lumens where as glare is just an angle, or the way that light is dispersed and not collimated. Plus, brightness is from the perspective of the driver, not the one sitting in the opposite lane

This. Or will laser headlights be like a constant laser jammer to the cops, and laser detector/jammers will be no longer be necessary?

[color="Indigo"]Most lasers are focused narrow color band coherent energy source. In simpler form they use LED or light emitting diodes. Incandescent Light is mostly scattered waves of light while the laser they are lined up and all going the same direction. Controlling the spectrum of light used and the finite focus of laser will allow headlights to pierce through fog, rain and lengthen visual distance and keep ambient light out of oncoming eyes. I think it will set off laser detectors alarms though . I want some : ) BTW the best headlights I have had were the Hella Quarts Iodide type, better than halide imho

For all those that say that this will set off laser detector / jam laser speed gun.

As far as I know, the laser speed gun pulses light, and measures the doppler effect on the wave packet using a particular frequency laser. So the headlight laser will first have to be similar enough in frequency to be confused with the speed gun signal, and even then I'm sure the circuits in the speed gun / laser detector can be made to do fast fourier transform to take out the DC component of the signal, which would correspond to the non-pulsing light from the headlamp.

www.google.com

Or maybe he's a physicist. For basic stuff like this it's real hard to tell the difference between someone with experience and someone who knows how to use Google effectively.

It's very true, and that raises a serious question about what we need to be teaching kids at school. Memorizing facts really means so little at this point, as you can google/wikipedia anything. On the other hand, the ability to sort out the BS from real information is probably the kind of critical thinking that you need in this age.

But the real question that I have in my mind is, what the hell does Hip2be do? How is it that he seems to understand every single automotive technology that ever pops up down to the details? This bothers me a lot since I completely disagree with his political viewpoints, and therefore his knowledge level does not fit my liberal world view at all. Why can't people that disagree with me have some courtesy and just be dumb, that would make everything so much easier.

Google + OCD is my guess. Maybe even an Aspie given his unnatural fixation on 2 door sports coupes. In any case I don't see his posts any more so they don't bother me one whit.

Hmm.
Anecdotes of event vs technical knowledge that it can but doesn't know if it does.

I think they can and they will. Set off laser detectors, that is.

Hey, don't put words in my mouth. Although, what you described is more Scrappy in my mind. Is Hip even a Republican? I think he would find the Rs to be too pro-government. (Wait, I may have opened a whole can of worms here)

Well I could easily believe that the current crop of laser detectors are ****ty enough to be fooled by taillights. What I'm saying is that it is certainly VERY feasible to make a device that won't be.
