MCL165 Series 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 trailer lighting. LED lights are more efficient, use less power, and last much longer than incandescent lights.


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.


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.

Video Transcript for Optronics GloLight Thinline LED Clearance Light Review

On this enclosed trailer, we're going to review and install the Glow Light Thin Line Clearance Light. Part number MCL165AB. Now we're working with the amber color today, this is also available in red as part number MCL165RB. This is our light right here. Couple of things dealing with the length, is going to be 3 7/8 inches long. From here to here, 1 1/4 high, and the thickness from here to here is going to be 7/8 of an inch.

Take a look at the backside, two simple poles, one's going to be ground, one's going to be hot. Very simple to install. This part number you get this entire assembly right here. The base such as in this example right here, is sold separately. This is a completely sealed unit, so you can use this .. There's a clearance side application right here, or you can use it in marine trailer applications as well.

Now this is an LED light, and this uses ten diodes. It's a very super bright light. Very easy to install, let's go ahead and do that. Set our new one to the side, and remove our preexisting light. Now there's a catch on each side, and on the inside as well where the contacts are, is a press fit. inaudible 00:01:07 similar to remove and install.

We'll use a flat bit screwdriver to kind of release the edges, and pull out on it. You may have to pry around a little bit on it as well, to get it to come out. A little patience and it pops right out. Maybe a good idea to go and clean this area out first, and then install our new light. It may help to use some kind of tool to probe around in there, and clean out the tabs.

Maybe scratch it up a little bit to. Make sure you have good contact, and get rid of the dirt. We'll take our new light, and put it into place. Line up the contacts, and push it in. That's all it takes. We'll go ahead and apply power to it, and make sure it works. Of course we're in daylight, it's a little bit harder to see, but look closely we got we got one, two, three, four points of light on our clearance light here, compared to a conventional two bulb incandescent setup here. With that, that will finish it for a Glow Light Thin Line Clearance Light from Optronics. Part number MCL165AB.

I spent a lot of time on the internet looking for bright LED clearance lights. I happened upon these GloLight marker lights. I was a little hesitant but have been nothing but pleased. The lights seem to be of sufficient build to keep the water out for years to come. Many LED lights put light out in a straight patter I wanted a light that gave general area lighting and this fits the bill. I drive a lot in the pitch black. It is nice to be able to clearly see where my trailer is at at all times. I would definitely purchase these lights again. I purchased the amber as well as red marker lights. I also purchased the tail markers and the effect was dramatic. Way brighter than the old LEDs I had on it. 589647

Ordered new LED clearance lights, taillights and clear interior lights to replace the non LED versions. They were shipped immediately with a confirmation. They were exactly as illustrated and what we needed for our horse trailer. Also came at a nice price!! Would recommend shopping on their site 686816

Trying to swap out my trailer lights to LED, so the draw on the battery is minimal. There are so many variations on the solid color, I had to measure and keep measuring. The solids have 10 Led’s But no such luck is it’s the fender lights that are both amber and red. I guess one company can’t do it all. It would be great to include the mounting plates, especially at this price. And also to sell multi packs of two or three. I only need two amber and two fender dual color, but need seven red. Shipping was sort of slow compared to today’s shipping speeds. Back in the day it would have been speedy. Times they are a changing. Packaging was weak. Each light has a plastic bag, but maybe only two were still in the bag. Maybe some sort of sealed plastic bag would have been smart. I’m guessing these will work fine. I thought we had to be careful of the Positive and Neutral leads for LED lights because we can damage them if they go on backwards. I guess we shall find out. Thanks etrailer for actually having this product with such extensive documentation and videos. Other websites ain’t got nothin on you. 654218


Comments

We do have several light bracket options linked at the bottom of each product page for each light. There are different configurations, and colors to suite your specific needs. At this time we do not offer these lights in a multi-pack configuration.

Looks clean and simple. Works well and can be easily replaced if something impacts an area of your trailer. Easy to install, but make sure you use low profile mounting hardware. A nice low profile screw works well, but a cap head screw will create an interference when clipping this light to it’s mount. 521326

I have found that the LEDs burn out much quicker than the incandescent bulbs, but because the LEDs burn out one at a time, I get about the same amount of use. The burn out may be because my alternator puts out nearly 15 volts which exceeds the capacity of the LED. I like the LED light because it is much brighter, even with burned out LEDs. 421989

- MCL165RB
by:

In general, I am very pleased with the LED marker lights I ordered. One bit of advice, there is a "zero clearance" fit between the light itself and the mounting base. Therefore, the only screw that will work must be a tapered head which sits, fully recessed, within the mounting holes. The lights did not come with any mounting screws, so you must source your own. 389352

I installed these on a 2004 haulmark 8.5 by 24 enclosed trailer. When the trailer was originally assembled, the light bases were attached to the trailer with a large pan head screw. These screws are very tall and interfere with the base of these led lenses during installation; meaning the lenses will not snap into place by just a fraction of an inch. Grinding a small amount of material off of the pan head screw gave these lenses enough clearance to snap into place. The lenses appeared to be made very well, and I hope they stand up to ultraviolet light. Very pleased. 258083

After one year, these lights are proving durable. Very pleased.

Review from a similar Optronics GloLight Thinline in Trailer Lights


I have a 2004 haulmark 8.5x24 and had a difficult time finding these replacement lenses. I was very happy to find them in an LED version. Installation was relatively easy; however, the metal pan head screws used to install the original light bases were too tall for these lenses, and I had to grind them down in order to get these lenses to snap into place. These lenses appear to be made well and I hope they will stand up to ultraviolet light without fading. Very pleased. 258078

Review from a similar Optronics GloLight Thinline in Trailer Lights


The only other way to get a drivers attention would be to slap them up side the head! Great looking, eye catching, extremely bright especially at night. The only problem I had was one of the lights wasn’t water tight. After a rain storm, I found about 1/4” of water at the bottom of one. This was the same problem I had with a previous led light. Evidently the hermetically sealed light wasn’t hermetically sealed. I alleviated this problem by drilling a small (.016”) weep hole in the bottom. I’ve taken a few pictures to show the quality and brightness of these lights. Lights off, lights on during daylight and at dusk. The picture of the lights at dusk is not the intensity of brake lights but just taillights. 435848

Nicely made LED brake/turn & tail light. Sealed from moisture. Don't forget to order the silver base to mount the light. I was able to trim the base on each end so that the LED piece fit on a slightly curved surface. Without the base that would not have been possible. I mounted these lights on the rear of my truck topper for towing with my MH. 608595

Review from a similar Optronics GloLight Thinline in Trailer Lights


One of my old LED tail lights had a few diodes fail so I started the hunt for a replacement. I wanted something with a fairly bright output so people will know that I am there. I spent quite a bit of time searching the internet and reading reviews before arriving upon these. I was a little skeptical about the "glow" but I LOVE them. They more than exceeded my expectations. There is a version of these tail lights that have reverse lights and I almost got that for those dark nights when I put the trailer away. These put off enough general light it almost isn't needed, though it would still be nice so others would know if I was backing. I took the opportunity to replace all the trailer lights and bought the GloLight amber and red side markers as well. I am out in the country so at night there is almost no light pollution. It is nice to be able to see exactly where my trailer is at all times. I would buy these all day long. I actually own a second enclosed trailer and am considering putting these on even though those haven't failed yet. I have also purchased from etrailer in the past and always had a great experience and this was no different. 589639

Review from a similar Optronics GloLight Thinline in Trailer Lights


These are a very high-quality... I love the glow they give off, unlike regular LEDs these are intense but not overwhelming and they really make my trailer visible day or night in just the tail light mode which was the biggest worry I had. But when the brakes are applied it's so bright that there's no doubt I'll be stopping and nobody will be confused of that... I'm going to get more of these for the other trailers I have, they make me safer at night by far. And they are bright enough I really don't need backup lights, the glow is amazing... 544152
