Optronics MCL157RB GloLight Red LED Side Marker and Clearance Light Dimensions

Innovative GloLight Design

This red LED light serves as either a side marker light or a clearance light. The light gives your truck or trailer a distinctive look that's completely street legal. This Optronics GloLight has a unique solid light pattern when lit, so your lights stand out from the rest. Optronics GloLights are a great way to add both style and value to your truck or trailer.


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 diodes or circuit board.


LEDs vs. Incandescent Lights

The long-lasting, cool-burning LEDs make this light the perfect replacement for incandescent vehicle and trailer lighting. LED lights are more efficient, use less power, and last much longer than incandescent lights.


Surface Mount Technology

The surface-mount technology used to construct these lights protects the LEDs from shock and vibration better than through-hole technology because the diodes are soldered directly to the surface of a printed circuit board instead of attached with wires that run through holes in the board. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability, and durability.


Simple Installation

Back of Optronics Glow light showing standard 2-prong plug mount

This GloLight has a standard 2-prong plug as pictured above. A 2-prong pigtail with mating plug (A46PB or A49PB - sold separately) is required to connect this light to your vehicle or trailer. An optional mounting bracket is also available (BK55BB - sold separately) to make it easier to mount the light on your 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 light on your trailer - one as a front or rear clearance light and one as a side marker light.


Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A56GB, A56GB or A57GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

etrailer does provide a wide range of products with different price points so the customer has a lot of choices to make the decision that is right for her\him. You also offer good online support documentation and your technical staff is also very helpful in helping the customer make the right choices.
Unfortunately, you left me with a very bad experience. I ordered a full set of lighting & wiring to redo our quad trailer from the 7-pin plug to reverse lights. A large order. I erroneously ordered 2 reverse\turn single lights, which is on me, so I expected a restocking fee (a little excessive, but that's the inventory business). I had to return the 2 wrong lights and order the correct one. I returned both lights, but etrailer said they only received one, which I was 99% sure I returned both. You had no interest or showed any flexibility considering maybe I was correct. This is a one year review you have asked me to submit and the light you claimed I did not return, still has not shown up in my garage. I liked dealing with you on numerous occasions, but I have taken my business elsewhere. That was a sad experience.

I have had these installed for a year now on my 14ft utility trailer. I love these lights! They are strong, durable, bright, and look so super cool at night! Most recently, last month, I trailered 1500 miles and through the mountains in West Virginia. They held up through curves and bumps and rainstorms and even dime-sized hail! I would recommend these to anyone who needs this style of light! I wish I had brackets enough to put two on each side... just so it would look extra bada**!



by:

The Igor worked great. I had a heck of a time trying to order lights for the trailer - either not getting the ones I intended getting or mismatched lights. But you came through like me a champ. Thanks.



by:

Was not happy with the packaging. GloLights were not packaged, just placed loose in the box with other items. One piece of brown paper in the box for a void filler. Lights were scratched up when arrived.

  • Rubber Grommet for 2.5 Inch Running Light Which Fits a 2.75" Hole Cutout
    The Rubber Grommet # A56GB will fit the Red # MCL157RB or Amber # MCL157AB 2.5" lights and requires a 2.75" hole.

  • Recommendation for Bright, 2-1/2 Inch, Round, Trailer Tail and Clearance LED Lights
    The Peterson Piranha LED 2-1/2 Inch Round Trailer Clearance Light, 3 Diode # 162R light that you referenced is certainly a bright trailer light. This 3 diode LED light will be brighter than a standard trailer light for you. I have attached a review video of the # 162R and the # 162A for you to see what the lights look like when they are on in the dark. The Peterson Piranha lights will install on the trailer using a 2-wire pigtail and grommet, # 162-18K. These LED light will work great...

  • Is GloLight LED Trailer Clearance or Side Marker Light P2 Rated
    I checked with Optronics and can confirm that the GloLight LED Trailer Clearance or Side Marker Light # MCL157RB is P2 rated. To mount this light you can use the 2-1/2" Round Grommet # A55GB for flush mount or 2-1/2" Round Grommet # A57GB for a recessed mount. It will require 2-Prong Plug # A46PB. The GloLight LED Trailer Clearance or Side Marker Light # MCL157RB is red although there is also an amber version of the exact same light at part # MCL157AB. I have added links to video reviews...

  • Is the Heavy Duty Light Bracket # BK55BB Compatible with Optroncs Glolights
    Yes, the Heavy-Duty Metal Mounting Bracket # BK55BB that you referenced would work with the Optronics Glolight Amber # MCL157AB or the Optronics Glolight Red # MCL157RB but you will need a grommet as well. For that you would want a Round Grommet # A57GB. For wiring up the lights you will want a Two Wire Pigtail for Sealed Trailer Clearance, Side Marker Lights # A46PB.

  • Looking for Trailer Clearance Light to Fit 2-5/8 Inch Rough Opening
    I'd recommend the # MCL59RB for red or # MCL59AB for amber. The lamps are sealed and are waterproof, perfect for a snowmobile trailer. Each LED lamp is 2-1/2 inches in diameter. With the lamp, you'd use the # A57GB grommet, which requires a 2-25/32 inch hole, which is about .156 of an inch larger than the 2-5/8 inch hole you referenced. If your 2-5/8 inch measurement is right on the mark, it would take just a few moments with a Dremel or a round file to slightly enlarge the existing holes...

  • Recommended Clearance Light And Grommet For Older Snowmobile Trailer Rebuild
    The clearance light I recommend for your snowmobile trailer is part # MCL57RB. This is a 3 diode 2-1/2 inch round light. It does require a rubber grommet for installation. The grommet to use for installing this light I recommend is part # A57GB. You may need to take a small round file and open the mounting hole you said measured about 2-5/8 inches but this should work well for your trailer. To connect the light to your trailer wiring I recommend using the Two Wire Pigtail, part # A46PB....

  • Availability of Oval and Round LED Lights Which Fit in Rubber Grommets
    There are both oval and round LED lights which may work for you but we do not have the dimensions of rubber grommets for specific trailer manufacturers. For an oval LED light with a grommet, the GloLight # STL111RB is 6-7/16" Wide x 2-5/16" tall and fits in grommet # A70GB. A round LED light that may work is the GloLight # MCL157RB which is 2-1/2" Diameter x 1-3/16" deep and fits in grommet # A55GB. I've added links to video reviews of each of these parts, as well as links to our pages...

  • HIghest Quality Trailer Tail Lights & Marker Lights With Grommet
    If you want the highest quality and most eye-catching trailer tail lights, then I highly recommend Optronics LED lights with a plethora of diodes. Let's go ahead and start with the tail lights with stop, tail, and turn functionality. The best lights, as well as the needed grommet and wiring pigtail is the following: - Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 48 Diodes # STL70RB - PVC Grommet # A70GB - 3-Wire Pigtail # A45PB This is a 6-1/2" long x 2-1/4" tall...

  • Availability of a Flush Mounted 2-1/2 inch Diameter GLO Light Led Trailer Light
    The Optronics GloLight # MCL157RB that you referenced is designed to be recess mounted with the Recess Flange # A57GB. While it wouldn't quite be as flush mounted as the Optronics GLOLight LED Stop/Turn/Tail Light # STL101RFMB that you also have it would look pretty good on your trailer. For a very similar 2-1/2 inch LED light that is designed to be flush mounted check out the # MC57RB. For a flush mounted grommet you would want part # A55GB.
