Optronics Red LED Diamond Marker Light 1 x 2.5 Trailer Clearance Side Light
Compact sealed red LED clearance and side marker light for trailers, trucks, campers, utility bodies, and replacement marker light applications.
Overview
The Optronics MCL-13RB is a compact red LED clearance and marker light designed for trailer side marker, clearance, and identification lighting positions where the size, lens color, mounting footprint, and wiring style match. The sealed housing and lens help protect the internal diodes from road spray and weather, while the low-draw LED design provides consistent light output without replaceable bulbs.
