>Then I later read that this is a bad thing, because the stock housings project light in a way designed for the stock bulbs, and you should swap them out for LED friendly housings.

Yes, 100% true. With these drop-in LED kits, you either create excessive glare, poor sight distance for yourself, or most likely both.

There's probably going to be some people coming into this thread and screaming about how this LED or that LED helps them see better. They honestly believe that. But the issue is that as the testing above shows, LEDs do not create the proper beam pattern in halogen housings. You can get excessive glare, and if you try to compensate for that, you end up losing distance light and getting a whole lotta foreground light, which helps you see exactly what it is that you're going to hit. You want light to help see what you don't wanna hit, not light that's 30 feet ahead of your F-150 because that's only going to help you see what you're about to run over at speeds over 30 MPH (44 feet per second).

Foreground lighting, unfortunately, is the number one determinant of how people rate headlamps. People think that foreground lighting is a good thing, and people subjectively prefer a lot of foreground lighting, and headlamp designers know that, but we cannot blow up the foreground with light as that would literally make cars more dangerous. These LED kits almost always create a ton of foreground light, which provides a false sense of security.


>Even more later I found I want to install a leveling kit, as my front hitch is a little lower to the ground than I want. So that creates the potential of LED bulbs in the wrong housings AND pointed straight at people's eyeballs.

You ideally want to use the headlamp adjustment screws on your headlamps to aim them downward slightly after lifting the truck. This would ideally be done with a headlamp aiming machine.

If not available, this is acceptable.

Thank you for keeping other drivers in mind!! It really benefits you to keep glare in check, especially after a suspension adjustment, as it could be keeping other drivers from running into you after being dazzled by your lights.
