The J-72 is a curb side LED box trailer light designed for stop, turn, and tail light service on compatible trailers. It is a replacement-style LED option for J-70 box light applications and is intended for the passenger side only. This curb side version does not include a license plate light.
Trailer tail lights are commonly confused by side orientation. This J-72 listing is for the curb side / passenger side light only. Match the side marking on the light and compare the mounting pattern before installation.
Compatibility: Designed for J-70 replacement-style trailer light applications where the housing size, mounting slot spacing, side orientation, and wiring requirements match.
Vehicle / System Fit: Used on trailers requiring a curb side red stop, turn, and tail light assembly.
Installation Notes: Confirm the light is installed on the curb side / passenger side. Side-specific lights may not interchange correctly with street side versions.
Performance Insight: LED trailer lights provide a replacement option for older box-style trailer lamps while retaining the familiar rectangular red lens format used on many utility, boat, and cargo trailer applications.
Selling Brand: Aftermarket trailer lighting replacement
Application Reference: J-70 is used as a replacement-style application reference only. Verify the current light’s size, mounting slots, and side orientation before ordering.
What This Means: This listing is for one J-72 LED curb side trailer light, not a pair and not a street side light.
Before Ordering: Verify side orientation, dimensions, mounting slot spacing, lens style, connector or wiring setup, and whether your trailer requires a license plate light.
When replacing trailer box lights, the most important fitment checks are side orientation, license plate light requirement, and mounting pattern. A curb side light is typically the right/passenger side light and usually does not include the plate light function.

LED replacement-style trailer light for J-70 box light applications where the mounting and size match.
