What's wrong?
The 7 x 9 combination LED stop, tail, turn, reverse lamps on the 2016 Custom Truck & Body Works Ford F-550 and 2018 Custom Truck & Body Works International 4000 handle several rear lighting jobs in one housing. They show braking, tail-lamp position, turn signaling, and reverse movement so drivers around the truck can judge what it is doing.
On affected trucks, the LEDs produce more light than the maximum allowed by FMVSS 108. Testing tied the issue to the lamp design after a supplier change for the PCB assembly, which is the circuit board that controls the LEDs. The concern is not that the lamp goes dark. It is that the lamp is too bright and can affect another driver's vision.
There is no warning sign before failure. An owner will not hear, feel, or see a separate symptom from inside the cab, because the issue is the light output from the rear lamp itself.
Who's affected?
The scope is split between Ford and International truck platforms, both listed under exterior lighting.
| 2016 Custom Truck & Body Works Ford F-550 | Exterior lighting |
|---|---|
| 2018 Custom Truck & Body Works International 4000 | Exterior lighting |
| Units affected | 2 |
| Field incidents | NHTSA has logged no field incidents to date. |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Excessive warning-light brightness can affect other drivers' vision and increase crash risk when the light is in use. Until the lens filter is installed, use extra care around traffic and avoid unnecessary glare toward other drivers. Repair will be free at any franchised Ford dealer once available.
What should I do?
- Check your VIN to confirm your Custom Truck & Body Works Ford F-550 or International 4000 from 2016 or 2018 is included in this recall.
- Wait for Custom Truck & Body Works instructions before scheduling service, because the remedy is not listed as available in this source slice.
- Contact a franchised Ford dealer about the free lens-filter repair that dims the excessive reverse-light brightness.
- Call Custom Truck & Body Works customer service at 1-888-712-2962 with questions and reference recall number 21V143 when you call.
- Bring the recall notice if Custom Truck & Body Works sent one, and ask that the 7x9 LED Stop-Tail-Turn reverse-light lens filter be installed free of charge.
What happens at the repair
The known remedy is an ECCO lens filter that dims the Stop-Tail-Turn reverse light. Once Custom Truck & Body Works opens the dealer repair, a Ford technician will install or provide the filter free under the recall. Parts and labor are covered. Out-of-pocket repairs already paid are handled through the lamp manufacturer's warranty or goodwill program, not through a separate reimbursement program. Ask the service desk how that warranty or goodwill coverage applies if you have prior repair paperwork.
