More often than not you can blame the auto industry for this. People want to migrate to LED lights for longevity reasons but the industry has no interest in OEM support for models that have already been produced, especially in the realm of upgrading/mods, so you end up with people dropping in cheap ebay replacements that have been developed without any consideration to the concentration of the beam or the design of the lens. If there was some level of first party support even to just the bare minimum of "here's how you should do it and here's the components to buy" you'd see a lot less of these issues since it's likely not the brightness of the bulb that's the issue but the way the lenses and housing were designed. In addition LED lighting has become so cheap it should be the complete default for every model but instead OEMs have decided to use it as a bargaining chip for higher trim packages.
