Over the years, I’ve noticed many trucks, originally designed for flush mounted, aerodynamic headlight assemblies, that were instead outfitted (somewhat awkwardly) with sockets for single sealed beam headlamps, often the 7" round type. An example is the pair of WHITEGMCs shown below.
I’ve also noticed arrangements where quad rectangular sealed beams had been replaced with single round units, as on the Freightliner FLD pictured.
These have seemed most common in LTL fleet trucks (notice the companies in the two examples), although not exclusively.
So what’s the reason for this? Is it that the manufacturers are offering sealed beams as standard on the cheapest trucks (which is what these fleets are buying)? Or is it because the replacement of sealed beams is faster or cheaper...or that it’s easier for a trucking company to keep a single type of headlight in stock network-wide?

Why sealed beams?

The pro about them is that they do not go milky like plastic lenses. Ever seen a volvo headlight? a lighter has more light than the headlight.
