Optronics Clearance or Side Marker Light with Reflex Reflector - Submersible - Rectangle - 2 Diodes - Red Lens Diagram

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the internal components.


Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

I bought 5 of these market lights to replace the market lights in the rear of my 1999 Winnebago Rialta. The size was very close and I opted for the low energy use LED version. After they were all installed, one of the LED lights did not work. Hence I took one star off. Make sure you test them before you go through the trouble of installing them. Since I just wanted to get the job done before the expected rain, I modified one of the lights and reused the bulb and holder from the original light. I did have to make some slight modifications to make the wiring work and the install was a bit tricky since there is no excess wiring protruding from the body of the Rialta. I was able to solder new wires on and make the connection. After one year they are all working fine and there is no moisture intrusion.



by:

Thank You for the product. However this trial run was less than satisfactory.
Other companies delivered the same product in original packaging that contained the light, a weather tight gasket, And fastening screws. All We received was the light. In a envelope. You asked.

Thank you for your review. The hardware is not included but these are already waterproof so no weather tight gasket is required.

Product was a direct replacement (ok, it may have been a updated version but same form, fit and function) and works like a charm. Shipping was good and on time. If I need more I know where I'll be ordering from. ;)

  • How To Remove The Lens On LED Clearance or Side Marker Light # MCL40RB For Installation
    I have included a link to our product video of the similar Amber Clearance Light # MCL40APB below. This has the same design with an amber lens and in the video she demonstrates removing the lens. You can also slide a flat head screw driver between the lens and back of the Light # MCL40RB. Then you will be able to twist the screwdriver to separate the 2 parts. Be sure during installation no Silicone # FAS59FR gets on this part of the backing and it would make it very difficult to remove...

  • How To Remove Optronics LED Clearance or Side Marker Light # MCL40RB For Replacment
    To remove the Lens # A44RB from the LED Clearance or Side Marker Light # MCL40RB you will need to place the tip of a flat head screwdriver between the lens and light assembly(see image). I recommend starting near the corners to reduce the risk of damaging the lens. Once you have the lens removed you will see the screws used to mount the lights. As this hardware is provided by the trailer manufacturer I cannot tell you exactly what it will have but a Philips head button screw is most commonly...
