What’s the Issue?

When the defect is present:

• Trailer turn signals may not flash when the vehicle turn signal is activated

• Trailer stop lamps may not illuminate when the vehicle’s brakes are applied

• Trailer brakes may fail to operate (if equipped)

Safety Risk

Non-functioning trailer lighting may prevent other drivers from recognizing changes in direction or speed, increasing the risk of a crash.

Additionally, the loss of trailer brakes can reduce stopping capability and further raise the risk of an accident—both occurring without prior warning.
