Semi Truck Universal Sealed Beam Headlights

Nowadays, it goes without saying that if your headlight bulb burns out, you replace only the bulb. If the lens cracks, you can easily find the replacement that will fit perfectly. But it was not always like this. From 1939 till 1984, it was mandatory to equip all vehicles with sealed beam headlights where none of the parts can be replaced separately. Sealed beams feature a parabolic reflector, tungsten filament surrounded by gas, and a glass lens fastened permanently together as one unit. At first, all sealed beam headlights had two or more filaments in a single assembly to ensure low- and high-beam functionality. However, later, manufacturers started offering two separate light assemblies, one for high beam and another for low beam.

Most modern cars and trucks feature composite headlights that come in a wide range of shapes and designs. They not only provide superior illumination but also give a vehicle a distinctive look. Sealed beam headlights are used very rarely today. However, you may still find them on older vehicles or some new heavy machinery or tractor-trailer trucks. While most composite headlights surpass sealed beams in style and brightness, the latter are not without their advantages. They are affordable, and unlike composite headlights with plastic lenses, sealed beams don’t become dull or opaque when exposed to the elements. And, these lights are extremely easy to replace on most vehicles.
