The LED Autolamps 42RM is a red LED rear end outline marker light in the classic truck style, featuring a chrome bracket, polycarbonate clip-in lens, and a clear lens design with internal red LEDs. Measuring 74mm x 38mm x 35mm with a 28.5mm bolt hole spacing, the 42RM is a widely used rear and side marker lamp for trailers, caravans, trucks, and commercial vehicles across Australia.
ADR approved under Category 49/00 (CRN 42839) and IP67 rated for complete weatherproof protection, the 42RM operates on both 12V and 24V systems with a minimal current draw of just 0.05A at 12V. The clip-in lens design allows lens replacement without removing the bracket, and the 16cm cable provides a practical lead length for most mounting locations. Supplied as a single unit in blister packaging, with the chrome bracket version (42RM) distinguishing it from the black bracket alternative (42RMB).
