Optronics MCL65A24B Thinline LED Clearance Marker Light Dimensions

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.


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 trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL65A24B Review

Speaker 1: Today we're taking a look at Optronics Thinline Sealed LED Marker and Clearance Light. This light is designed for 24-volt systems. The small, rectangular trailer light functions as both a clearance light and a side-marker light when properly mounted.It features a sonically-sealed, waterproof design when it comes to the housing and lens unit. It is submersible.LEDs make great replacements for incandescent lights. They last longer, they burn brighter, and they're much more efficient. You don't have to worry about changing bulbs, and you don't have to worry about burnt out filaments with LED systems.This unit features a polycarbonate lens and housing that's very strong and durable.

It has a nice yellow lens on it.This light mounts using a mounting bracket. The mounting brackets are sold separately and available at etrailer.com. This would be an example of a mounting bracket here.On the back of the light, we have two prongs. The prongs would line up right there in the bracket. Then the bracket would grab through the mounting hardware.

Then it provides a single wire for a power wire.Now each bracket might be a little differently on how it grounds and how it wires. Basically, all you got to do is plug this into the bracket, and then the bracket will provide the wiring that you need for your application.That's really all there is to it. The brackets are available at etrailer.com. They are sold separately.This is a P2-rated light. It's SAE and Department of Transportation compliant.When it comes to the overall dimensions, starting with the overall length measuring edge-to-edge, it gives us a measurement of 3-15/16" long.

The overall width is 1-1/4". The overall depth from front to back is about 7/8" deep.This unit contains a total of three diodes or three LEDs. We're going to go ahead and hook it up to power. Then you'll be able to see what it looks like. I'll also turn the overhead lights off.What I'm going to do is just plug this into the bracket.

Again, brackets are sold separately, available at etrailer.com, and then I'll go ahead and hook this up to power.So you can see here the light sends out a nice, consistent signal. Again, it contains three LEDs or three diodes. The multi-diode design really helps optimize the overall light output. Optronics puts a lifetime warranty on their LEDs.That's going to do it for today's look at the Optronics Thinline Sealed LED Amber Marker and Clearance Light.

Great light, very bright. Only thing is wires aren't labeled to the function they control. Only complaint is length, I wish the light was 3-4 inches shorter.


Comments
The wiring functions for each wire on this light are: White wire for ground, Black wire for tail light, and Red wire for turn signal.

I was looking for lights to add to a receiver hitch cargo carrier for nighttime visibility. These were perfect for size and function. The housings were sturdy, the wiring was sealed and they worked on the first try, as tail lights, turn signal and brake lights. Would definitely recommend these!

Still working perfectly 1 year later!!

The day pic's were from 6:30 p.m. 06/07/19. Notice you can't see the stock taillights from 10 ft. away. Hence my purchase of these LED lights for the angle iron uprights. The night pic's are 2 ft. from my garage door at 9:30 p.m., 06 07/19, and this is what drivers behind me will see. These LED's are slim, well made, water proof, and attach like a breeze. I LOVE THESE LIGHTS!!!!!! As I told Carol, the pigtail wires should be 11/2 to 2ft. instead of 8". My only downside to these lights. I Have 3 trailers and from now on etrailer.com is my go to site!! Thanks a million, great product.

These tail lights work great on my custom built wheelchair trailer. They are bright, easy to mount and function as needed. They've been on the trailer for a year with regular use and no problems to date.

Review from a similar Thinline in Trailer Lights


The lights were awesome. We added them to the back of a 16' flatbed trailer just under the back lip. The lights were in addition to the regular taillights. The idea was if someone was to close to see the side lights , they could see these from the back. They were also easy to install, we just tapped into the regular taillights. We are thinking about adding these to our dump trailer as well.

Still great 1 year later. Awesome buy.

I bought these incandescent for my leeisurelite trailer so i could stop hyperflashing. My trailer worked o k on 2014 limited but not 2017 cvo limited. When u have a cvo the bcm is totally different. Badlands and custom dynamic don't have a load equilizer for cvo. I put these lights on the front of my trailer and didn't have a problem. I couldn't put a Universal 5.6 Ohm Turn Signal Load Equalizer for Harley-Davidson® because they heat up. I couldn't put it inside the trailer (heat)or the outside because not waterproof. The incandescent lights work. Cheap and the easiest fix. I also had a isolator harness.

O K no problems

I wish I would have discovered etailer.com and specifically this light 2 months ago! I am redoing a snowmobile trailer and wanted to update the lights. I have less than 2” to work with. After ordering multiple style of lights I finally discovered thin light gold! This saved my project and works great! Now all I need is snow!


Comments
It has been over a year since my purchase from etrailer.com and the lights still work great! I have put these lights to the test and they have held up wonderfully! Couldn’t be more happy! I will definitely be a return customer for future projects!

Product was as I was hoping for. Fast delivery and product was just as I expected. Install was an easy install and gives the rear of the trailer the added lighting that I wanted for other vehicles to be able to see my intentions when changing lanes and stopping. Am very satisfied with the purchase and if I need more lighting Etrailer is were I will purchase. All the lighting will be changed at some point including LED side lighting. Prices at Etrailer are some of the cheapest that I have found for quality lighting.


Comments
The lights are still operating as good as the day I installed them. They definitely brighten up the rear of the car hauler that I installed them on.

Just what I needed to add an additional safety/signaling light in a car towed on a car dolly. The lights show very clearly through the tailgate window.

I wanted additional brake light visibility higher up on rear of my camper. The STD lights were low and partly obscured if I was hauling bikes on their rack. There was no good way to run wiring inside and I didn't want holes as possible leak points. So I mounted these thin, bright LED lights high along outer edges, connected wiring to existing brake lights, encasing wiring in heat shrink tubing and siliconed all in place. Looks good, works great!

I decided it was time to repair the lighting on a 15 year old trailer due to several being broken, and the rest being very faded. I spent quite a bit of time on etrailer comparing options I finally settled on the 4 diode led's. I was excited to see the difference but was ultimately dissapointed with my decision to swap out the old incandescent with more costly led's as the new led lights put out significantly less light. As u can see in the pictures I did the passenger side first, then I took pics halfway thru. If u look at the driver side with old lights it has alot more light even though it only has only 2 working lights, compared to the 4 on the new side! In the front shot u can see the old on the right is casting 10 times the amount of light on the ground. On the plus side at least the orange is now orange, and the red is red instead of almost clear. I will say the shipping was very fast, and the the customer service was awsome as always.

Review from a similar Thinline in Trailer Lights


The lights are still working well. The installation was a bit of a bother because there were 4 wires on the original, 3 on the replacement. After some rewiring, it worked fine. It required a little cutting away of the RV wall to allow a small part of the back of the light to go through so the light was flush with the wall, but it wasn't that hard. The lights are bright and add a bit of safety to driving the RV in the dark.

I bought this to replace the third high mount brake light on my 4 Runner. I wanted a brighter light due to the large number of drivers on cell phones and not paying attention to traffic. This light is at least 8 to 10 times brighter and is absolutely perfect. I mounted it directly on top of the existing light and just drilled a hole through that light to run the wires. I used two sheet metal screws to secure it to the frame and filled the open space in with clear caulk. I did not use the existing mounting hole because I wanted to aim the light into the face of the driver behind me. Seriously, we have a real problem with drivers on cell phones. Shipping was fast. I was stunned that the light was packed for shipment in 3 hours on a Sunday morning. You people should really take Sunday off.

One year later and this light still looks brand new. It survived an unusually harsh winter with no problems. It is definitely a FIVE STAR LIGHT.

I have a 2010 international trailer. I was unable to find exact match parts so I went to etrailer to find comparable parts. These 3 way tail lights were 5 inches longer, as posted in the description, than the ones that were on previously. I just drilled a new hole each for the wires and one screw and used one of the previous screw holes. These lights are bright and I was happy with the flush fit on the trailer.

When I transport my dirt bike, it obscures the tail lights on my Jeep. So I needed a tail light that I could mount to a motorcycle rack that fits into my hitch receiver. This product was a perfect fit. It’s thin, bright, easy to mount and looks good. etrailer has always made it easy to find, purchase and ship parts for what ever project I’m working on.

Review from a similar Thinline in Trailer Lights


Haven't hooked it up yet but tried it out on a 12 volt battery and it looks good, works fine. Wire colors are a little confusing but maybe that's the proper convention. White goes to ground, red to bright stoplight positive, black to running light positive. No instructions came but easy to figure out. Shipping time was excessive but maybe covid accounts for that.

Wow, what a difference LED clearance lights make, especially at night. It makes my business information really stand out and people who follow me really notice that. I've been wanting to go LED the past couple years and now that I recently made the change, I'm not ever going back to standard low-level light bulbs again. Thanks etrailer for offering these lights and at a very affordable price. You were almost half the price as our local part store was selling them for, plus these are more stylish as well.

Perfect. Still shining bright as ever.

I replaced all of my exterior travel trailer lights for LEDs, and etrailer was my go-to source. These thinline strip lights were a new addition, because I wanted higher visibility with the tail lights. The thinline lights were tied in with the existing tail light wiring and work great. What I find most attractive is the clear lens and slim profile, so they are not detracting from the white fiberglass trailer's design. Also pictured are 4 Tail Lights (STL78RB) with chrome accent rings (A78CB).
