Optronics MCL157AB GloLight Amber LED Side Marker and Clearance Light Dimensional Diagram

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.

The lights are well made, much brighter than what was on our motorhome originally and look really good. Pricing is competitive. I would not hesitate to buy from etrailer again. 559966

So far so good. Got the lights installed and tested them out and they look great! I will say packaging was questionable, they were loosely packed in a box that was too big with no bubble wrap or stuffing to keep them from bouncing around or against each other. Thankfully none appeared cracked or broken, and hopefully it's a sign of their toughness and not a sign of etrailer's lack of care. 383215

Great lights. I get asked about them everywhere I go. Super bright and being led they are have very low amp draw. I led a small caravan once in heavy rain. Those that were behind me could not believe how well my trailer lights blasted through the rain. 525292

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

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

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

Review from a similar Optronics GloLight in Trailer Lights


Great Product, it's good quality and will fit perfectly for the trailer I use in my Air Conditioning, Heating & Refrigeration Business. The only problem is I ordered the wrong side. Wasn't sure if by the which one was the left or the right? I was looking at the trailer form the front when I determined it was the left one but it appears your suppose to look at the back of the trailer when you do that. Guess I will be ordering the otherside here shortly. Maybe I can get an exchange or if not then I will have a spare and hope if it does get broken again it's the other side. Etrailer has some really good quality stuff at a very good price. I got my hidden hitch from them at a Great Price. They even had a video that showed me how to install it. A couple of the local places here wanted 3 times the amount of what I paid to provide the hitch and install it for me. Will never go anywhere else for any trailer parts or accessories. 21144

I really like these lights. I use them for my rear lighting and rear side marker/turn signals.

They are bright and have a distinctive look. 524591

Peterson trailer lights started cross feeding between 1157 incandescent brake and taillights. After checking all wire splices and cleaning trailer to tow vehicle plug connection, the problem persisted. It wasn't horrendous but still bugged me; so I tried Optronics LED's. No cross feed with the LED's, and to my eye the LED's are brighter in direct comparison with 1157 still mounted in the lower position. 190153

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

The lights on line didn't seem to put out enough light. But I got them installed and they work great, and they are very visible. I rebuilt a 1963 Aristocrat 13 ft. it's called the "Lil Loafer" buy the factory and I wanted round lights to replicate the originals, these are round and almost the exact same size and it doesn't hurt my feelings at all that they are LED lights.. 484192


Comments

I still am impressed as to how noticeable they are at night. No I never regretted purchasing those lights, easy install, work great. And the trailer originally had round tail lights. I have just purchased another set of tail lights from you, just a couple days ago. Again Oval shaped 52 diode LED. These are going on a trailer that I cant find anything about, other than it was manufactured in San Jacinto California in the 1980s. I think these new lights are going to look great on there, I think original was probably an ugly square one. The trailer is a 19 ft. , 1983 Tow Lite fifth wheel single axle. I swear it was built for off road the way it looks, and it looks stock.

Great Light! Put two on the back of a toyhauler for backing up. You will need the grommet and pigtail to do it right. I had to cut two oval holes for mounting in trailer frame. Take your time with the layout and get the right sized hole saw, makes installation pretty easy. 586398

It might be possible to give 5 stars but after purchasing all the products about a year ago, my little fiberglass trailer is not even close to being ready. All the lighting is hooked up and they all seem to work, so that's a good thing. The other products that I purchased have not been installed yet. I would like to mention how pleased I am with e-trailer videos showing everyone how their products look and how they're used. Keep it up, I am a happy customer. Vic 366257

Although rubber gasket did fit into my 4 7/16" hole the LED tail light did not fit with gasket installed. I had to make my hole 4.5" and then I had to apply a lot of force to get the tail light installed into the rubber gasket. 538284

Review from a similar Optronics GloLight in Trailer Lights


Quite frankly, these are one of the nicest LED taillights I've seen. The glow of the tail-lamp is very modern and it's very bright. These replaced old halogen square tail-lights on a 2005 toyhauler, and it helped freshen up the look of the rear. I had to drill a few holes in the metal plate these attached to, as the three wires must have a direct exit so that they don't get pinched. Initially, these flashed an error code on my 2018 Superduty when I tested the turn-signals, but when I tested them again, the error code went away. Be aware that swapping out halogens for LED's on a trailer may make your tow vehicle throw a turn-signal error. 538942

These are some pretty sweet lights. Very bright and attention getting. I am constantly getting compliments on them. The High Points- - I bought the standard 3 prong style, works just fine with a Truck-Lite plug and with a no name one I had lying around. - When not using driving lights both the outer and inner lights flash for turn signal. Don't remember reading about that, but it's pretty sweet(at least for the people behind me!). - All 4 arrived in excellent shape and with all lights working. Now, for the only negative that I can come up with- - 2 of the lights have what I think is a sliver of white plastic stuck between the outer circle and the cover. I'm guessing it's from pressing the halves together. They can't be seen until you're very close to them, but for a $28 light it's a bit disappointing for that to get past QA. Regardless, I highly recommend these, they are very distinctive and so far I haven't seen anyone else with them. Can't wait to be able to afford 4 more! 99525

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
$21.96
would be brighter, but would not be DOT compliant if used as a back-up lamp.

Ask the Experts about this Optronics Trailer Lights
Do you have a question about this Trailer Light?


  • 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...

  • 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. The LED equivalent...

  • 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.

  • What Pin on the Hopkins Endurance 4-Way Flat Trailer Connector Is For Side Marker Lights
  • 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.
