Arthur T Knackerbracket has found the following story:

It might be stating the obvious, but your car's headlights are a safety device, and not all headlights are created equal. For a while, carmakers have been fitting powerful LED headlights to their high-end offerings, but more often than not, their cheaper cars—and particularly cheaper trim levels—get saddled with much-weaker illumination. But sometimes a commuter wants to see more of where they're going when the sun goes down. Eventually, they go looking for a solution, starting with their local automotive parts store. But stuffing aftermarket LED headlight bulbs into OEM housings designed for conventional halogen units results in dangerous glare for oncoming drivers. While LEDs can deliver more intense light at a higher end of the spectrum, most aftermarket units also create a hazardous condition.

The major brick-and-mortar auto parts stores know this, which is why they tend to shy away from aftermarket H11 LED bulbs, other than ones clearly marked for use in fog lamps or "for off-road use only." It's a different world online, with off-brand H11 LED bulb listings on Amazon, eBay, and Walmart websites failing to carry the same prominent warnings.

You can get pulled over for non-spec headlamps, and for a good reason. In addition to issuing a citation, the law enforcement officer may have the legal right to force you to remove the bulbs. More ominously, once the officer has pulled you over, you risk a vehicle search. With all that in mind, it would be wise to keep a set of securely packaged OEM bulbs in the glovebox or trunk if you are running aftermarket LEDs.

Although Consumer Reports tests new vehicle headlamps, it hasn't tackled the topic of LED replacement bulbs, despite Consumer Reports' extensive resources. A comprehensive Consumer Reports aftermarket LED replacement bulb test would go a long way to bring clarity to the market. Consumer Reports' testing of conventional replacement bulbs found that while aftermarket units can improve headlight brightness, there's much more to it than that. "Distance and how far a headlight illuminates is governed more by the reflector (behind the bulb) or the lens (ahead of the bulbs). While you can change the bulb, you are not changing the distance, i.e., not necessarily improving safety."

    This is increasingly a problem with bicycles as well. LEDs are replacing halogen bulbs, giving a much bluer light, and they're brighter. Because LEDs can be quickly toggled, they're made to flash, to increase battery life. Combine that with a bunch of numpties who aim their lights straight forwards or even up, and you get bike lights that destroy your night vision and then go dark. Then they come back and dazzle you again. Cycling towards anyone with those lights is quite scary.

    > numpties who aim their lights straight forwards or even up

    Unfortunately even reasonably decent bike lights don't offer very good positioning, owing to the wide variety of handlebar diameters and shapes. I often find myself stopping to wiggle my bike lights when they slip around the handlebars. It isn't always obvious that I am blinding other road users...

        Back to high school shop class may not be an option for young-uns? Guessing you are a boomer like me, back when high schools had shop class (which I enjoyed greatly). It was eliminated quite a few years ago, at least in my old high school.

      Around here there seems to be a lot of idiots who wear super bright (like over 1000 lumens tightly focused) on a head band or mounted on their helmets. These lights wind up being higher than even jacked-up pickup trucks and aimed right in oncoming drivers eyes.

        The conventional wisdom with cycling is that you're supposed to have a helmet-mounted headlight like that if you're mountain biking, so you can point the light where you're looking. But if you're on a road bike, you're supposed to use a handlebar-mounted headlight instead, and NOT a helmet-mounted one.

        That said, when I've gone cycling at night on the multi-use trail in my city, I don't recall seeing anyone with helmet lights, only handlebar ones.

    Driving towards them isn't that great either.

    unrelated story; Was driving in Berkely California recently, a Cyclist started to wander into my fender so I honked to alert him to that. At the next light he catches up and pulls directly in front of me and then goes WAY slower than he was before. Holding up myself and the 10+ cars behind me.

      Proper response: a reserve horn.

      200 Hz, 120dB.

      When they projectile shit themselves right through their spandex pants squirting over their saddles, you can drive around at a sedate pace.

      Please don't honk cyclists.

      A car horn may sound loud inside a vehicle - but it sounds terrifying outside the car. One has to consider what happens if the terrified cyclist now falls off - right underneath the wheels of your car.

      The cyclist knows you are there. Unlike the vast majority of other road users, they know exactly where each corner of their vehicle is on the road and relation to others. If a cyclist appear to be inattentive or doing something that appears strange... just back off a little, give them some space and pass them when it is safe to do so.

      a Cyclist started to wander into my fender

      Just calmly remember there are multiple perspectives. I can very easily see that scenario from the perspective of the cyclist: they are riding along in the proper position and a car puts its fender dangerously close to their rear wheel. Cyclist perceives a road hazard up ahead (a pothole, for example) and judiciously asserts their safety cushion by forcing the car driver to allow them more room. Car driver doesn't understand and leans on the horn to "punish" the cyclist. Cyclist points out that two can play at that game.

      Cyclists and motorcyclists understand that making an error is a life or death proposition - the cost is so much higher so they are hyper-aware of their surrounding and they will have seen things that other road users simply won't have even registered. Potholes, slippery paint, oil on road, rocks, blind corners, driveways. That taxi pulling up on the horizon that will have cars overtaking it on the wrong side of the road in ten seconds' time. They are aware of it all.

      It doesn't hurt to back off a little. Don't use the horn. It's painfully loud and scary outside the car cabin. The last thing you want to do is have to go to court and explain how a cyclist ended up underneath your car.

    Many motorcyclists have run this kind of flashing headlamp for decades - more important to be seen than for others to be able to see anything else, I suppose.

      As a bonus, it gives some people an epileptic seizure. Not too mention the people who get migraines from the flashing lights. How they're legal is beyond me.
      Today I was getting followed by a bike, even in the Sun it was blinding me with its twin headlights (non-flashing), then he passed me, sounded like his motor did about 20 grand. I was doing 80 in a 60 zone and he was just about instantly gone. Rural area but lenough driveways, side roads and the odd kid or horseback rider. Idiot. Speeds are in kmph.

      Not only does the flashing light kill your night vision, it kills your sensitivity to motion. Suddenly everything looks like it's moving - therefore much harder to detect actual motion, like a dog or person stepping out between parked cars or a door opening in the bike lane. Those flashing lights are dangerous for the rider as much as annyone else.

      When a two wheeler is killed, the usual claim by the perpetrator is that she did not see him.
      Yes, I was in this position, but survived. A mother made a left turn on me and I flew over her and her two children for 20 feet.
