I'm not too mad about incandescent tail lights. It's obviously a thing because they needed to keep costs low and a separate tail light for the Lariat trim didn't make sense to R&D. Thankfully its easy to buy a set of VLEDs LED bulbs which don't error and swap them in for brighter. It also keeps the trims kinda consistent with the rest of the lineup, the Lariat 2021 F150 has the same halogen tail lights, gotta step up to a luxury trim for LED tails.
Maybe they'll add a King Ranch / Limited / Platinum trim with SYNC 4, Blue Cruise, LED all around, and whatever else in the years to come.
