Those instructions need to go to the dolts who my wife complained about on our drive home this evening. It was about 30 miles entirely over rural highways. My wife complained more than I did - "I wish those guys would dim their lights!" or "I hate those bright lights! Why isn't that illegal?" Most people driving at night are sensible and responsible. But there's a significant number who just do not bother to turn their high beams off. There's also a significant number who either say "MFFY, I'm leaving my brights on" or who might think "Wait, you mean there are two settings for my headlights??" Those latter ones are the ones I'm calling low IQ. And compared to totally self-centered and abusive, low IQ is charitable. Ohio must be different. I have experienced over-bright headlights, and headlights that are poorly aimed, but have never been anywhere that drivers commonly neglected to dim their brights for oncoming motor traffic. In many locales behaving that way would be tempting homicidal road rage, not to mention traffic citations. OK, more details. First, my complaints apply mostly to two different rural routes I have to drive at night, typically once per week. These are two lane state highways in farm country. One is hilly and curvy. Each drive is a bit over 30 miles. Most drivers are fine, but I can count on at least two or three that handle their high beams badly. I know that it's unscientific to rely on general impressions, but ISTM that pickup truck drivers are over represented among offenders. They are also far more likely to have auxiliary driving lights running, which also add to the glare. I suspect some of this goes along with the "rolling coal" mentality. Is it just inattention, or is it MFFY? I've had a couple incidents where I've flashed my brights to ask them to dim theirs, and they responded by turning on their auxiliary lights. I once described in detail here where a pickup driver sat across from me at a red light with his high beams on. When I flashed my brights, he turned on a super-bright light bar at the top of his windshield. As to not knowing how to operate the lights: A few years ago I was a passenger in a car driving a similar rural road. We have a problem with deer crashes, and I expressed surprise that this person did not have her high beams on, since there was no other traffic. In response, she said "I don't even know how to turn them on." I had to tell her to push the turn signal lever forward. I don't understand what was wrong with the ergonomics of the little button on the floor. Never saw one break, either, which I can't say for overly complicated turn signal levers. It would be pointlessly antagonostic of me to flatly contradict your version of something that happened to you :\ So I'll just repeat that your corner of Ohio seems to have uniquely bad behavior with high beams. Where I live: * There are some glaring low beams, although the really obnoxious bluish ones (Xenon HID?) are thankfully thinner on the ground than they were a few years ago. * The group of drivers most likely to delay dimming their headlights are not red neck pickup drivers, they are q-tips in late model El Dorados, who probably shouldn't be driving, at least at night. * Drivers *do* respond to enforcement. I could point out several local crosswalks where drivers will almost certainly yield to pedestrians, and many similar ones where a random driver faced with a pedestrian would as likely hand him a winning scratch ticket as yield. The same is true for "no turn on red" signs. I believe the difference is (very) local enforcement. Refusing to dip high beams strikes me as an infraction likely to result in a ticket -- when deciding whether to dip it's impossible to tell whether the oncoming vehicle is a police car, and I suspect that cops are at least as easily annoyed by high beams as ordinary drivers. * Although I see a lot of needlessly creative driving, I would be quite surprised to see a driver simply refuse to dip his lights to oncoming auto traffic. Not dipping to bicycles would surprise me a bit less. -- |

Once the desire We aren’t talking about hi-beams so there’s no question about the cyclist being at fault for being poorly lit. -- duane |

They're very different with the xenon doing different things of each type. This covers the differences: "What is the difference between genuine XENON HID lights and Xenon gas-filled bulbs?" https://www.preciseflight.com/support/questions/faq/3/ An HID (high intensity discharge) bulbs is usually filled with xenon gas and has no filament. One can also use any of the noble gasses, argon, neon, krypton, and xenon, or a mixture of these. An arc ionizes the gas, which produces a plasma, which then lights up in various colors. Some colors: https://en.wikipedia.org/wiki/Gas-discharge_lamp#Color Xenon filled incandescent maps operate similarly to halogen filled incanscent light bulbs. The idea is to slow down the rate of tungsten evaporation from the filament. To do this the filament and bulb need to run very hot. The halogen gas or mix literally bounces the evaporated tungsten back to the filament.
