The Jammy J-70 is a right / curb side rectangular trailer lamp used for stop, turn, and tail light functions on 12V trailer lighting systems. This light is commonly used on trailers and RV-style applications that use a classic red box lamp with two removable mounting studs on 2" centers.
Before replacing a rear trailer light, match the lamp side, mounting pattern, and wire functions to the existing light. A left and right lamp may look nearly identical, but the turn / stop wire color and side assignment matter during installation.
Compatibility: Fits trailer applications where the lamp dimensions, stud spacing, wire functions, and right-side orientation match the original light.
Vehicle / System Fit: Designed for 12V trailer lighting systems requiring a right-side stop, turn, and tail lamp.
Installation Notes: Disconnect power before installation, confirm each wire function, and test stop, turn, tail, and ground circuits before road use.
Performance Insight: Correct right-side wiring is important because the stop / turn circuit must match the trailer’s passenger-side signal circuit.
Selling Brand / Style: Jammy J-70 box-style trailer light
Application Reference: Trailer, camper, RV, boat trailer, and utility trailer references describe common use only. Fitment should be verified by measurement and wiring function.
What This Means: This listing is for one J-70 right / curb side stop, turn, and tail trailer light.
Before Ordering: Verify lamp size, mounting stud spacing, trailer side, wire colors, and connector or wiring method before installation.
Rear trailer light issues are often caused by poor grounds, corroded terminals, broken wires, or incorrect left/right wiring. Replacing the lamp is only one part of the repair; test the circuit before assuming the light itself is the only failure point.
Built for the passenger side of the trailer where the green right turn / stop circuit is used.
Combines three core rear trailer lighting functions in one rectangular red lamp assembly.
Common rectangular style used on many utility trailers, boat trailers, campers, and RV applications.
Mounts with two removable studs spaced 2" center to center for compatible trailer brackets.
