Excerpts:
The 11 trucks evaluated have a total of 23 possible headlight combinations. Fourteen of them have excessive glare, contributing to their poor ratings. A vehicle cannot earn a rating better than marginal if it produces too much glare in any of the five test scenarios.
A bright spot in the ratings is the headlight system on the Ridgeline's RTL-E and Black Edition trims. The LED projector low beams provide fair to good visibility on most approaches, with inadequate visibility only on the gradual left curve. High-beam assist, a feature that automatically switches on high beams if no other vehicles are present, makes up for some of the deficiencies of the low beams.
The Ford F-150, the centerpiece of the best-selling F-Series line, is among the poorest performers. Both the base halogen and the optional LED low beams provide inadequate visibility in all test scenarios, including both sides of the straightaway, on sharp curves in both directions and on gradual curves in both directions. The LED lights also produce unacceptable glare. The high beams on both versions have mostly inadequate visibility too.
