What's wrong?
The LED illuminated school bus signs on 2021-2022 Ic Bus Ce school buses are the front and rear stop signs that light up when the bus is loading or unloading students. They are supposed to stay sealed from water, dirt, and road contaminants so the LEDs and wiring keep the stop signal visible to drivers around the bus.
On affected buses, the black textured back plate around the sign's weather seal can become compromised. That lets contaminants enter the sign housing and reduce the sign's performance. In certain cases, contamination creates an electrical short that leaves the illuminated stop sign inoperable.
There is no warning sign before failure. A driver or attendant learns something is wrong when the illuminated stop sign works poorly or stops working.
Who's affected?
The same LED illuminated school bus sign appears under both equipment and exterior-lighting components across the 2021 and 2022 model years.

What's the safety risk?
An inhibited or inoperable LED school bus sign reduces visibility for oncoming drivers and increases the risk of a crash. If the sign is not working as intended, schedule the recall repair soon and limit trips until the sign is replaced. Repair is free at any franchised Ic Bus dealer.
