What's wrong?
The intermediate clearance lights on 2009-2018 Supreme Curtainside trucks are exterior marker lamps mounted along the angled roof rail bracket. Their job is to make the truck's side and upper outline visible to other drivers, especially from an angle or in low light. On these trucks, the lamp location and lamp angle matter as much as the bulb itself.
Affected Curtainside trucks use Trucklite Model 36 intermediate side lamps with 30 degree lights on the angled roof rail bracket. That setup does not meet the FMVSS 108 visibility requirement because the light has a limited viewing range from that mounting position. Supreme determined that a 45 degree clearance light gives the needed range for the same roof rail location.
There is no warning sign before failure. The lights can still turn on, but their placement and angle limit how well other drivers see the truck from the side.

What happens at the repair
At the dealer, a Supreme technician replaces the 30 degree intermediate clearance lights on the angled roof rail bracket with 45 degree clearance lights, so the truck is more visible to other drivers. The replacement parts and labor are free under recall 18V541. Supreme has a general reimbursement plan on file for owners who already paid for this related light repair before the recall work.
