    I don’t understand how LEDs were ever allowed with the same sockets. What legitimate use could that be.

    … plus this has somehow gotten so popular that my garage, part of a major regional chain, offered to replace my headlights with LED replacement bulbs

    … although I can see the personal motivation. When everyone else seems to be causing so much glare, you need all the help you can get

      On the basic end: because they’re cheaper, use less energy, are more reliable, and last longer.

      On the fancy end: have you seen demonstrations of Audi’s matrix LEDs? They have the ability to dim specific areas dynamically, so that they can track incoming traffic and keep them in a dim-zone while still keeping the road and shoulders well lit.

      Keep in mind that there is nothing special about LEDs that make them brighter; they can make LEDs dimmer and they can make halogens brighter, but the manufacturer has chosen not to.

        Sure, but making them with the same socket, so they fit in the same place, despite having different beam shape and reflector requirements, is entirely wrong.

        My car has LED headlights and they fantastic. They also have a very sharp cutoff meant to keep it from blinding others, assuming correct alignment. It also claims to have the hardware for active matrix and will turn that on as soon as they get approval

        My older car that I keep for my team has noticeably dimmer lights. I’d really like to convert to LEDs and I know there are some that fit and are sold as replacements. But I know they’re not. Those manufacturers need to be fined for every kit sold like that

          I think the key part is “the LEDs could be made dimmer, or the halogens brighter, the manufacturer chose not to”.

          It makes sense for plain ol halogens to share the same socket as plain ol LEDs, because they function in the same way and are the same brightness.

          But bulbs of different characters probably should have different sockets, so that high-intensity bulbs of any kind (eg xenon, laser, led) cannot be used in a regular lighting fixture without the necessary hardware to make it safe.

          But here we have another problem - standardizing car parts is very beneficial to the owner because it makes repairing much easier and cheaper; if every manufacturer uses their own connectors for everything, then vendor lock-in would get that much worse and replacement parts would get that much harder to find and more expensive.
          If manufacturer we’re encouraged or forced to use standards, and we’re instead encouraged not to, then they’d all make their own proprietary connectors for everything forcing you to get all maintenance done at official dealership where they can charge extortinat prices.

          So it’s kind of a damned if you do, damned if you don’t scenario. I think all we can do is regulate the behavior we want to see, and fine manufacturers, garages, and drivers that violate it.
