First of all, this is on a New Jersey major highway, not some country road in the middle of nowhere. You don't NEED headlights like that. Secondly, have some consideration. Unless you ate too many paint chips as a child, you have to realize that your headlights are blinding people when you pull up too close.

I pull over and let them pass, also, but since I am from New Jersey, I am obligated to give them the finger at my side window as they pass, just in case they are looking.
So you are mad at people for using the headlights that come equipped on their cars? What are they supposed to do, change them after they buy the vehicle? You go so far as to call them idiots, then flip them off when they pass you?

I also drive a sedan and get blinded by these lights, but I don't blame people for using the standard equipment on their vehicles.

Every car needs those headlights. There's certain advantages that come with being able to see everything in front of your vehicle at night.

A high school football field has their lights directed down at the field yet from a great distance away one can see a glow in the sky.


Anytime you direct light down wards on a dark night there will be a glow upwards.
That certainly doesn't mean that the lights are focused wrong.

Not why I made the post at all, its about waste of energy with far too many lights being used in a downward postion but streaming out lights from above , and waste of energy in most big shops too. no need for it, A new road is being added near Glasgow and it has no lights as yet , but people are managing the same with their headlights on.... Im not saying have NO lights, IM saying cut the lighting and stop the waste of energy into the sky.surely it can be harnessed more. http://news.bbc.co.uk/1/hi/sci/tech/4794249.

By its own nature and that of its environments, light is subject to scatter. It does not long proceed in a straight line from a point-source. It ends up going all over the place, and it's not like you can somehow mop up what's been sloshed over onto unintended targets. Light does have a cost however, and when that cost starts to exceed perceived benefits, it becomes likely that less light will be produced.

I blame them for pulling so close they are shining those lights in my mirrors. It's rude and dangerous. As you point out, yes, they come with the vehicle. The drivers KNOW that, don't they? So why be so aggressive with those lights on the highway?

Poor quality designed lighting is the problem on roads I feel and loads of energy is wasted.

Night-time light pollution is exacerbated by poor lighting design, installation and maintenance providing illumination outside the area of benefit. This results in light emitted in unnecessary or unwanted directions. Street lighting is usually required to illuminate the road surface and objects below the level of the light source, but poor lighting design can lead to significant proportions of light emitted upwards or at the horizontal. Commercial lighting (such as illuminated advertisements) and architectural lighting may be specifically designed to emit horizontal or vertical light, as do most emissions from road vehicles. Horizontal and near-horizontal light emittance increases the visibility of light sources from a distance, increasing the potential to disrupt animal navigation, and significantly increases the illuminated area, in turn increasing the encroachment of light into adjacent unlit areas. Moreover, due to the long path lengths of near-horizontal light through the atmosphere, light emitted in this direction produces more skyglow than that emitted upward, and much more than light emitted downward.

Maybe he wants lights to be replaced with lasers, that have more focused beams...
