Product Details

The Optronics MC57RBP is a 2-1/2" round, sealed incandescent side marker and clearance light designed for trailers, trucks, and commercial vehicles. Built to withstand harsh environments, this compact light delivers reliable visibility in a durable, moisture-resistant package.

Key Features:

  • Dual-function design — serves as both a clearance light and a side marker light depending on mounting position
  • Built-in reflex reflector — integrated directly into the red polycarbonate lens, eliminating the need for a separate reflector
  • Sonically sealed housing — fully submersible and waterproof construction keeps moisture out even when submerged
  • DOT/FMVSS P2 rated — meets federal motor vehicle safety standards for clearance and marker lighting
  • Recessed grommet mount — fits standard 2-1/2" round grommet opening (grommet sold separately); accepts standard PL-10 2-prong plug connection
  • Polycarbonate housing and lens — impact-resistant construction stands up to vibration and road debris
  • Low current draw — operates at 12V with only 0.2A draw
  • 90° beam pattern — 45° to each side of centerline for wide-angle visibility
  • Replaceable incandescent bulb — easy maintenance with accessible bulb replacement
  • 3-year warranty
