You aren’t losing your sight, it’s just that truck headlights are actually getting worse.
The life of a headlight is a difficult one. Not only is there the rational fear that if there is a head on collision, the headlight is one of the first components to lose its life, but it has to fill a tall order in order to be considered any good. According to the IIHS, headlights have to be both bright enough to light up the road but also dim enough to reduce glare for oncoming traffic. So how many pickup trucks sold in the US meet this mark sufficiently? Not many apparently. Hopefully this changes on the new Mercedes pickup.
Trucks like the hugely popular Ford F-150 scored low on the test. This is the case with either the halogen headlights or optional LED lights installed because they were unable to provide adequate visibility.
The worst performer of the group was the Chevrolet Colorado, which only allowed drivers to see 120 feet ahead on a straight road. Out of the 11 trucks tested, the only one that was rated ‘good’ was the 2017 Honda Ridgeline. An 'acceptable' rating went to the 2016-2017 GMC Sierra provided its spec’d properly while ‘marginal’ ratings went to the 2017 Nissan Titan and 2016 Ram 1500. Those that failed with ‘poor’ ratings were the 2016-2017 Chevrolet Silverado, 2016-2017 Ford F-150, 2016-2017 Toyota Tundra, 2016 Chevrolet Colorado, 2016 GMC Canyon, 2016 Nissan Frontier, and 2016-2017 Toyota Tacoma.
