Optronics MCL157AB GloLight Amber LED Side Marker and Clearance Light Dimensions

Innovative GloLight Design

Optronics Glo light side marker or clearance light lit

This amber 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 (A55GB, A56GB or A57GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Video Transcript for Optronics GloLight Trailer Lights Manufacturer Review

Brett Johnson: (silence)The Glolight is the stunning combination of premier lighting technology, meeting world-class style and capabilities. The introduction of the Glolight series represents the first truly different approach in years to the visual presentation of stop-tail-turn lamps.Most LED lamps have hotspots or patterns of bright light. Glolight lamps are visually distinctive from other LED lamps, because their lenses diffuse the light, giving them a smooth, bright, glowing appearance.The Glolight optical technology is so different, it's patentable. And Optronics has 35 new products with Glolight technology in its pipeline, right now. Mudd: Lighting is one of the most visibly predominant features on any vehicle, and this is a completely different looking yet highly effective light. We're focused on integrating the latest technology into our manufacturing process, and these new lights clearly represent the innovative partnership between Vanguard and Optronics.

Innovation is important to Vanguard, our customers, and our industry. Robert: Glolight technology looks different because it is different. Different in its optical approach and different all the way down to the circuit boards.We designed and manufactured all of our lamps using the most advanced engineering techniques, and test them in our own world-class, state-of-the-art optical testing facility. Lamps are engineered to resist everything, from shock, to dust, to high-velocity water spray. We're committed to designing and manufacturing erosion-resistant LED lighting products.

And Glolight lamps are produced using solid state, surface-mount device, or SMD, technology.Most LED lamps sold in the heavy duty market today, use what is typically referred to as "through hole" construction. Optronics LEDs are mounted directly to the surface of the circuit board, eliminating exposure to connecting points. LED lamps with SMD technology, like Optronics' new Glolight, are so robust that they can continue to function even if their circuit board is completely submerged in water. The unique Glolight lenses and housings are made of tough polycarbonate material that is sonically welded to create an impermeable seal. Glolight lamps meet all FMVSS 108 and SAE photometric requirements for visibility and safety.

And our lamps are tested at a certified, independent laboratory.I guess it's redundant to say this, but our lamps come with a lifetime warranty. Roush: There's nothing out there that's as eye-catching and effective as these Glolight lamps. Vanguard is always drawn to component supplier products that contribute to our customers' efforts to operate more effectively and safely. Glolight lamps just look different and more noticeable. And that means better safety.

Brett Johnson: With world-class manufacturing facilities, harness making capabilities, and a global market presence, Optronics is now changing the competitive landscape in HD lighting. We always have access to a lighting manufacturer with global sophistication, fleets are enjoying increased product availability, and everyone is befitting from new, innovative technology and the industry's most competitive pricing structure. With Glolight, Optronics is sending a signal that things have changed in the HD lighting industry.

etrailer made it easy to decide on the right clearance light because of all the information and photos. The order arrived quickly in the right sized box. Not a huge box full of paper or air bags.

Review from a similar Optronics GloLight in Trailer Lights


Optronics is a high quality brand. I love being able to see clearly behind me. I've backed over and into things; if I'd been able to see better, most could have been prevented. The backup lights make outstanding makeshift work lights for hooking up a trailer at night or changing a friend's flat tire. 644228

Put the STL111RB lights on my boat trailer a year ago, still working GREAT!!! In and out of Florida gulf coast saltwater at least once a week. These lights will probably outlast the trailer they are on. 593671

Review from a similar Optronics GloLight in Trailer Lights


Light requires the use of a grommet to fix it into a recess. A video of how the grommet is installed & works with the light would be helpful. I spend a lot of time getting the grommet with the light to fit nicely note the hole needs to be a little bit larger than the light which is dimensioned in its description. Looks and fits great once installed properly. Nice products! 511515

Review from a similar Optronics GloLight in Trailer Lights


I'm only giving you a little over a good mark. Service was great delivery was great. But I'm sorry the lite is falling short of what I had hoped for. I expected a much brighter lite. with that many LED's on it.. I will say they are brighter then stock. but in dark location need as much lite can get. 572139


Comments
Because this lamp is a back-up lamp, its allowable brightness is limited by DOT regulations. A utility lamp like # BUL43CB
Optronics LED Trailer Utility Light - Submersible - 10 Diodes - Round - Clear Lens
$25.34
would be brighter, but would not be DOT compliant if used as a back-up lamp.

Excellent product. Brightest reverse light I've seen. Installed on ranch hand bumper on 2012 f150. Customer service from etrailer was amazing! I was notified that my order may be delayed due to availability via phone and email. Was not delayed after all; was notified about the package being shipped days later and the rest is history. All over, I feel very happy with my purchase 238728

Couldn't find anything like this anywhere. This reverse light far outshines other 6" oval led types I've had and seen. Was rear ended recently, and the old ones of this same style were knocked out and run over. Fits my 2012 ranch hand sport series bumper. 490512

Review from a similar Optronics GloLight in Trailer Lights


These lights are pretty impressive for trailer lights. I would be lying if I said I didn't consider putting a pair of them on my truck. The appearance is excellent, function is excellent, and I am overall very pleased with these lights. I installed them on my flatbed and livestock trailers - both look phenomenal but the vertical mount on the livestock trailer is most impressive. Installation was a snap with the new rubber bushings (purchased from etrailer for less than $1/each). You just can't go wrong for this price. I haven't seen STT lights I have liked as well as these. As far as the shipping goes, I live in West Central Illinois and these items arrived in less than 24 hours with the standard shipping. You cannot, and I mean cannot, beat etrailer for customer-centered service. OUTSTANDING!!! 102044

These lights were added to my cargo trailer that I pull behind my motorcycle. These help to make sure that people see me when I am on the road. The lights were easy to install with the grommets and pigtails that I ordered at the same time. All the products worked together well and made the project easy to do. Love these lights and will buy more if needed. 403017

  • 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...

    If you take a look at the attached photo of the Hopkins Endurance 4-Way Flat Trailer Connector part # HM48110, you will see a two letter code for each terminal. The correct terminal for the clearance/side marker lights is shown as "TM" which is a black/brown wire. In regards to wire gauge, you will not have any issues using a 16 gauge wire from the lights to the 18 gauge wire on the trailer connector.

  • Difficulty Installing Optronics Market Light MCL157AB and Grommet A55GB in Bracket BK55BB
    You are not alone! The lights # MCL157AB have to fit tight in the grommet # A55GB and the grommet in the bracket # BK55BB so there is very little tolerances. One thing that I have had success with is to put the light in the grommet and then push both into the bracket together. Another tip that usually does the trick is to use some soapy water on the outside of the grommet to help it slip into the bracket.

  • Recommendation of Turn Signal and Parking Light for Off-road use
    I recommend the amber trailer turn signal and parking light # ST70AB as it's sealed and waterproof. The rubber grommet # a70gb will provide shock mount protection extending the life of the lamp. The Optronics # MCL157AB could possibly be used as a turn signal but not recommended. The grommet you referred # A56GB would work as it will provide shock protection especially that you will be off-road. It will seat properly once the light is plugged into the grommet.

  • 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...

  • 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.
