How to tell if I have projector or reflector headlights?
When you are choosing headlight upgrades, the first thing to figure out is whether your vehicle has reflector headlights or projector headlights. This has nothing to do with the bulb number on its own; and isn't even about what technology (HID, LED or halogen) it is. The key is to visually observe the headlight from the outside of the vehicle.
Reflector headlights are the traditional style that most older halogen systems use. If you look straight at the headlight and see a large shiny bowl or mirror behind the clear outer lens, with the bulb itself visible in the middle, that is a reflector. The inside often has stamped or faceted chrome surfaces that help spread the light. In a reflector system, the light source sits near the center of that bowl and the reflector throws light forward in a relatively wide pattern. While reflectors are usually associated with halogen, there are exceptions where manufacturers used HID in a reflector housing rather than a projector. A good example is the early Canadian‑spec Acura CL Type‑S, which came from the factory with D2R HID bulbs in reflector housings.
Projector headlights have a very different appearance. When you look at the front of the headlight and see a distinct round “glass eye” inside the housing, you are looking at a projector. Instead of a big open chrome bowl, you see a circular lens, often about the size of a golf ball, and the hardware behind that lens is largely hidden. Inside the projector is a small reflector bowl, a cutoff shield, and the lens, which together create a sharper, more controlled beam pattern with a defined cutoff line. Projectors can be built around halogen, HID, or LED light sources; the presence of a projector tells you about the optics, not automatically about the bulb technology. Many factory HID and LED systems use projectors, but halogen projectors are also common. Vehicles often have an outer lowbeam projector lens, and an inner highbeam/Daytime Running Light reflector lens:
If you are standing in front of a vehicle and trying to decide which type you have, the quickest test is visual. If you see a chrome bowl and a visible bulb with no separate round lens in front of it, you are looking at a reflector headlight. If you see a round lens that looks like a small glass eyeball, you are looking at a projector. Both types can use different kinds of bulbs, and there are edge cases like the Acura CL Type‑S where a reflector was paired with HID from the factory, but this simple visual check will correctly identify the housing type on almost every modern vehicle.
Thinking about your own car or truck: if you picture the headlight in your mind, does it look more like an open chrome bowl or more like a round glass eye inside the housing?
