Optronics Trailer Lights - MC57AB

2-1/2" Diam x 11/16" D; Sealed, waterproof; PC-rated; reflectorized lens; mount w/required grommet; 2-prong plug connection; 1-bulb incandescent

Sealed, 2-1/2" Round Trailer Clearance and Side Marker Light with Reflector - Amber

This sealed, round light can be used as a clearance or side marker light. This PC-rated light functions as both a marker and clearance light when mounted properly at a 45 degree angle. The amber lens is reflectorized which means a separate reflector is not needed to be DOT compliant. The light measures 2-1/2" in diameter by 11/16" deep. Lens and housing are one unit that is sonically sealed and waterproof, providing protection to the heavy-duty, long-life bulb. A mounting grommet and plug are required to complete the installation. A separate, industry standard, two-prong plug is used for the wiring connection, allowing for choice of several mounting and wiring options.

  • Amber, round light functions as clearance, side marker light
  • PC-rated light - functions as both a clearance and side marker when mounted at a 45 degree angle
  • Reflectorized lens is DOT compliant, eliminating need for separate reflector

Expert Answers about Sealed, 2-1/2" Round Trailer Clearance, Side Marker Light with Reflector - Amber - MC57AB                                            Do you have a question about this Trailer Lights?


  • Can Optronics Sealed 2-1/2 Inch Light be Mounted in a 2-7/8 Inch Hole
  • In order to install this light, you will need a grommet to fit the hole. We have a grommet for a 2-25/32 hole, which is just under 2-7/8 as well as a grommet that fits a 3 inch hole. If you can re-measure the hole with something that has 16th inch or 32nd increments we can get a more accurate measure of the hole. If it is a 2-25/32 inch hole, you would use grommet # A57GB. If you find it is a 3 inch hole, you can use part # A55GB. Both of these grommets will work with the MC57AB.
