Stop thinking about putting LED bulbs into your halogen projectors and get Oracle LED retrofit projectors. These projectors have the correct LED placement within the projector for proper light pattern. The only downside, and I an nitpicking, is the bottom of the pattern. That part of the lighting pattern is slightly more U-shaped than I would like; I prefer a wider spread. But then again, I put these in my lifted offroad vehicle, so the lights are higher off the ground to begin with. The other nitpick is the fan noise. The cooling fan emits a whir similar to what you would hear from a drone, just not as loud. All in all, it's a worthwhile retrofit to make. I will be purchasing another set for my other truck once I confirm the dimensions.
