What's wrong?
The affected exterior lamps are Code 3 7x9 Stop-Tail-Turn-Reverse All-in-One LED units installed on 2017-2019 Swab Wagon Pioneer medic bodies, including Chevrolet 3500, Ford F-350, and Chevrolet 2500 Hd models. Each lamp combines brake, tail, turn signal, and back-up lighting in a single housing. Its normal job is to show drivers behind the medic vehicle when it is stopping, turning, backing up, or running with rear lights on.
On these vehicles, the lamps exceed the allowed light output under FMVSS 108. The issue is not that the light goes dark. It is that the lamp is too bright, so the rear lighting can affect the vision of nearby drivers instead of staying within the required photometric intensity range. The filter kit corrects the output so the lamps perform within the permitted range.
There is no warning sign before failure. An owner or fleet operator is not expected to hear, smell, or feel a change because this is a lighting output problem, not a drivability problem.
