There are a variety of headlamps available for a vehicle, either mounted originally on your vehicle or sold on various aftermarket parts dealers. In North America, most headlights are of the sealed beam construction type. In this type of headlamp, the filament (or bulb), reflector and lens are fused together in a single, airtight unit. In European countries, sealed beam headlights are not allowed, and standard on most vehicles instead are the H4 halogen incandescent light bulbs. Other countries would also require daytime running headlights (DRLs) that provide low-bean headlights during the day and high-beam headlights at night.
Most new Ford vehicles come standard with automatic Ford headlights. This type of headlights automatically shifts light from low-beam to high-beam, depending on the lighting conditions at the moment you are driving your car. These headlights have integrated photo sensors that determine when to shift from low-beam to high-beam. The same specifications stand for most genuine replacement Ford headlamps, which are designed to function well with your vehicle and the electronic system it is equipped with.
Aside from the original Ford headlights, there are also various other aftermarket headlights that you can use to replace a damaged headlamp. Most of these headlights come in a variety of functional and artistic designs, like the Altezza headlights, Euro headlights, dual-beam headlamps and directional headlamps. An easy step in replacing your stock headlights with new aftermarket headlamps is to install one that is of the same type as the original—sealed beam to sealed beam, HID lamps to HID lamps.

A "stream headlights" kifejezés nem található, sosem hallottam róla, pedig sok tolmácsolási tapasztalatom van ezen a területen.
Az egyetlen ehhez hasonló szó még a strobe light, de ezt igazán nem tartom valószínűleg ebben az esetben.
