Description
Overview
J3 series reverse lamp insert restores reverse lighting in jumbo rear lamp setups and also gives you a standalone reverse lamp when the bracketed single-lamp format suits the job better. It carries its own reflector, so it keeps the rear lighting package compact while still covering reverse function and reflector visibility in one unit.
Features
- 24 LED reverse lamp with inbuilt reflex reflector.
- 12-24V multivolt operation suits common trailer and truck electrical systems.
- IP67 sealing helps the lamp handle exposed rear mounting positions.
- Includes the mounting bracket for single-lamp installs straight out of the pack.
Specifications and Materials
This lamp measures 190mm x 122mm x 30mm, runs a 10cm cable and uses a PMMA lens with an ABS bracket. It mounts horizontally onto a flat surface, and it can also replace the reverse section in compatible J2 and J3 jumbo lamp assemblies. Part number: J3WM.

Compatibility and Fitment
Check the lamp footprint, mounting position and vehicle voltage before ordering. This insert suits bracket-mounted single reverse lamp jobs, and it also fits compatible J2 and J3 series jumbo rear lamp assemblies when the reverse section needs replacement. If you are rebuilding a full jumbo lamp or replacing the bracket separately, check the related parts below before ordering.

Compliance and Safety
Mount the lamp horizontally, keep the cable protected through the panel and confirm the reverse light output before the vehicle returns to service. Also check the bracket sits flat and secure, because rear lamp movement can shorten service life on rough trailer and truck work.
Trailer Applications
J3 series reverse lamp insert suits trailer and truck rear lighting jobs where a jumbo lamp reverse section needs replacement or where a separate bracket-mounted reverse lamp better suits the body layout. Workshops also use it when refreshing older J2 and J3 jumbo assemblies without changing the whole lamp body.
Why Choose ICS Trailers
Choose this J3 series reverse lamp insert when you want the reverse section sorted without replacing more of the rear lamp assembly than the job needs. See more rear lighting in our LED Lights
