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.

I have a Triton trailer which had a blown out incandescent tail light. I decided to upgrade all the lights to LED. It took me only 30 minutes to change out all 13 lights. I used a little silicone spray and a small screwdriver and the old lights came right out of the rubber grommets and the new lights fit perfect. They are really bright and makes a big difference, glad I did the upgrade!

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. 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.

Review from a similar GloLight in Trailer Lights


Upgrading our 1998 Coleman Grandview, the old incandescent just seemed too dim. Nice light, only suggestion would be to list some wiring options, was a bit confusing going from the old Bargman to the new LED. But I read through the Bargman page here and got squared away. Pic is LED before anchoring compared to the stock on the right. BIG improvement.


Comments
Still great, nice and bright. They are a huge improvement over the factory incandescent signals.

This one is for the “driver” side. It has the lens on the bottom for lighting the license plate. (It does not include the license plate holder. I like this one because you just push in the wires. I recommend this light.

I really like the bright back up lights. It does take a little extra work for the back up lights. - Sorry this pic doesn't show the backup/stop lights but this is the great little chuckwagon we put them on.

The Optronics surface mount light (STL178RK1B) was easy to install and the 22 LED diodes provide exceptional light. The light fits snug on the trailer bracket and the foam gasket provides extra protection.

The unique "glowing" running light ring is very visible and the stop/turn LEDs are very bright. The light also came with an integrated standard connector, so no need to splice and/or purchase an additional connector.

Review from a similar GloLight in Trailer Lights


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.

Review from a similar GloLight in Trailer Lights


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!

Review from a similar GloLight in Trailer Lights


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.

Ask the Experts about this Optronics Trailer Lights

  • 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...

  • Determining If GloLight LED Trailer Light MCL157AB Will Fit PJ Utility Trailer
    It is possible that the GloLight LED Trailer Clearance or Side Marker Light - Submersible - 9 Diodes - Round - Amber Lens # MCL157AB you were looking at will work on your PJ Utility Trailer, but to be sure you would need to have a 2-1/2" grommet like the # A55GB in the frame of your trailer. If you do not have one you can add the # A55GB but you will need to drill a 3" hole for it to fit in. The # MCL157AB does not include the 2 wire harness, so you would also need the # A46PB. I...

  • 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.

  • 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. 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.

    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...

  • 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.
