2-1/2" Diam x 11/16" D; Sealed, waterproof; PC-rated; reflectorized lens; mount w/required grommet (sold separately); 2-prong plug connection (sold separately); 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 (sold separately) 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.

Video Transcript for Optronics Trailer Lights MC57AB Review

Today we're going to be taking a look at part number MC57AB. This is the Optronics Sealed, 2-1/2" Round Trailer Clearance and Side Marker Light with a Built in Reflector. It's a 1 incandescent bulb design. It is PC rated, that means it can function as both a clearance and side marker light when mounted at a 45 degree angle. It's going to have the reflectorized lens. It's Department of Transportation complaint so that's going to eliminate the need for a separate reflector. It's also going to have this sealed, waterproof housing in the lens unit.

That's a great design to have. A heavy-duty long life incandescent bulb. This does require a mounting grommet that's going to be sold separately. That's available with part number A55GB. The mounting grommet is going to require a 3" diameter hole in order to get it mounted. Here on the back side it's got a 2-prong connection so it's going to accept the industry standard 2-prong plug.

That's going to be sold separately, and the mounting grommet is sold separately as well. The overall diameter of the light is going to give us a measurement of 2-1/2" and the depth is going to give us a measurement of about 11/16". We're going to go ahead and connect this to our external power supply that way you can see what it looks like it with power running to it. I have an industry standard 2-prong plug here, just to show you how easy it is to connect it. Simply line up the connection points and push it in. It snaps in there to create a nice weather tight connection.

This is what the light's going to look like when connected to power. Again it's going to have a 1 bulb design and that is an incandescent bulb. It's got the reflectorized lens. It allows a lot of light output to come through; it distributes it pretty evenly and it's going to provide a nice, consistent light for you. This is going to function as both a clearance and side marker light when mounted at a 45 degree angle. That's going to do it for today's review of part number MC57AB. This is the Sealed, 2-1/2" Round Trailer Light from Optronics.

Equal to or better than the same lights available locally, but at half to 1/3 of the local prices. Even paying shipping I save a lot. Delivery with E-Trailer is always timely, too. 186572
