LED bulbs do not work well with factory housings

Headlights do what they are supposed to do. They are easy to install and just work. I can't blame them. But putting LED bulbs in standard packages is a bad idea. The problem is that the reflectors in the flashlight bodies are designed for a very specific position of the light source (where the filament is placed) and any deviation from that position throws off the entire projection of the light. If the LEDs were placed EXACTLY where the filament would otherwise be placed, the projection would be more or less similar. But that's just not true for every LED I've found. All are located differently, thereby losing the function of the normal body. I tried them on a 2012 Jeep Wrangler and immediately took them off because they were actually worse than stock headlights. Lighter of course; but the low beams dazzled other drivers, and switching on the high beams did little to increase the distance because the light source was misplaced. The difference between low beam and high beam was comically small. If I were to aim my low beams so that they didn't blind other drivers, the bright ones would probably only provide 5 feet of extra illumination. It really was that bad. For those of you with projector headlights, the same is true (albeit to a slightly lesser extent). A few years ago I tried some LED bulbs in my Chrysler 200 which uses HIR bulbs in a dual function projector. I also removed them almost immediately because the light pattern was too unstable and looked sloppy. They also didn't project down the street to the factory HIRs (because the lighting was so diffuse and out of focus). Also, the foreground has become too bright, and a dark foreground is needed for distance vision (where it really matters). Many seem to forget that. This is also an important reason why I am opposed to installing LED lights in cars that are not designed for them. I see much, much better with HIR on my Chrysler and Jeep than with LED lights. While the xenon look is attractive in the "I drive an expensive car" sense, it seriously interferes with your distance vision compared to otherwise sane HIRs. Joke time: I remember the #1 consumer complaint about the Chrysler 200 before I bought it. was for low beam. It was actually a [brilliant] design. The projector's low beam setting is intentionally dimmed to allow more light to be focused on the road when the high beams are on. A darker foreground not only brings more light from afar where it's really needed, but also means your eyes aren't adapted to the daylight. With a dim foreground, your pupils will dilate more and see light in the distance better (I suspect that's why almost every car automatically turns off the fog lights when you turn on the high beams). I can attest to how well this works - I drive a variety of vehicles and my night vision with the "modest" HIRs in my 200 is almost as good as any of the HID vehicles I've driven. The foreground might not be as bright as a headlight, but I don't count the pebbles in the road when I'm driving - I'm on the lookout for deer/pedestrians/obstacles a quarter mile ahead. sincerely suggest just replacing the bulbs with new ones (HIR if you can). Lightbulbs lose performance as they age. In the case of my Jeep, I replaced the 7 year old lightbulbs with brand new versions of the same lightbulb and it made a world of difference. And while headlights with blue SilverStar filament or another filament branded light put out some light compared to standard clear filament headlights, they still outperform ill-fitting LED headlights. For you and other drivers. If you still need LED/HID color temperature because it looks cool, I would try to find a replacement light body designed for LED (but good luck - many of those cheap Chinese ones will burn out quickly).

Pros
  • Nice to use
Cons
  • Communication with seller
