Optronics 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 or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL12RB Review

Today, we're going to be taking a look at the Optronix Uni-light, LED Trailer Clearance and Side Marker Light. This small, round trailer light serves as either a side marker lighter clearance light. It's going to feature a sonically sealed waterproof housing and inaudible 00:00:14 that is submersible. It's an LED system. And LED is going to make a great replacement for an incandescent light. LED's are known to last longer, they burn brighter and they're much more efficient.

You don't have to worry about replacing bulbs or worry about brittle filaments. Optronix actually puts a lifetime warranty on the LED. When it comes to the construction, we're looking at a poly-carbonate lens and housing. That's going to be a nice red lens. It is designed to be a recess mount, or a recess mount installation with a mounting grommet. Now, a grommet is not included, so that will need to be provided separately.

Your installation area is going to require 3/4 of an inch diameter hole, two wire pigtail. Now it does have a wire casing to keep the wires together for most of the wire length. Then it separates to two wires. The black wire's for power, white wire is for ground. This is Department of Transportation compliant, it meets FNVSS108 and CMVSS requirements for automotive lighting. It's a PT rated light, taking a look at the dimensions real quick.

Starting with the diameter, diameter's going to measure around 3/4 of an inch. Overall depth, it's going to measure around 7/8 of an inch. Then the wire leads . Coming out of the housing, there. See those are going to measure about 7 1/2 inches long.

It's going to contain one diode or one LED, so a single LED system. Power drill at 12.8 V, is 0.047 amps. We're going to go ahead and hook it up to our axle power source. That way you can see what it looks like with power running to it. We'll also be able to turn off our overhead light, so you can see it on the low light setting. You can see here that the light sends out a really nice, consistent signal. The red lens allows plenty of light to come through. You can see that it contains one LED. Again, LED's are going to burn a lot brighter, they're just overall a better light when it comes to some of the elements for lighting. Again, it's going to last longer. We're looking at a brighter light output as well as much more energy efficient. That's going to do it for today's look at the Optronix Uni-light LED Trailer Clearance and Side Marker Light.

Review from a similar Uni-Lite in Trailer Lights


I have finally finished the install of the great products that I’ve purchased from Etrailer. Curt 24K 5th wheel hitch, the lube discs, the front receiver hitch tube, the Factory 7-way connector and 7 -way extension (I have 3 7-way plugs on my truck) and the countless number of LED lights. The service is amazing and the customer service I received was fabulous. I really like these folks as they were vary knowledgeable about what I was after and pointed me in the right direction to accomplish my end goal. Thanks to everyone at Etrailer. I couldn’t have done it all without you.


Comments
Everything I’ve done to my truck with multiple products from Etrailer has just been perfect. All working and performing as expected. Couldn’t have ask for more reliable products than those I’ve installed.

These were designed as a clearance light application and at a great price. I bought them to use as turn signal lamps on my RZR. They are high quality and extremely bright when lit, so they work great for both applications. These guys have great parts at a great price and quick shipping. I would recommend them to anyone needing trailer/boat/lighting. Thanks guys.


Comments
John, Are these lights clearly visible during the day time? I bought some that look similar but are not bright enough to be seen. Im also using them for turn signals on my RZR.
-- comment by: Lowell C - 03/12/2016
Lowell C. These lights are bright enough to be seen during daylight. I use them when I am with a group to signal our next direction or 4 way as intent to slow. Everyone behind me have been able to see them even in high dust situation.
-- comment by: John C - 03/15/2016
Still loving it. I installed them as turn signals on my 12 RZR. Every time I go out riding they are utilized and many have made comments on how well they look and can be seen.

I installed these on my home built teardrop. Worked out very well. Total current draw is under 400 mA for all lights.

Review from a similar Uni-Lite in Trailer Lights


I bought a couple more of these two-diode LED clearance lights to add some more lighting to the rear of my kayak trailer. They work nice and are easy to install in 3/4" holes that I drilled through a piece of aluminum angle. The trailer has orange clearance lights on the front sides, red clearance lights on the back sides, the stop/turn/parking lights on the back, three red clearance lights on the back, and a white LED license plate light. It's really lit up and very visible at night from the rear and sides. Thanks to etrailer.com for great products and services!
My wife and I like to kayak, but we don't like to deal with putting our kayaks on roof racks on the top of a car. So I bought a used Load-Rite trailer that was designed to hold one Jet Ski, and added a frame made of slotted angle and 2x6 lumber to hold the kayaks, and a cargo box from Tractor Supply to hold kayak seats, life jackets, towels, sun-protection clothing, and some spare gear (ropes etc), and bought all new LED lighting from etrailer.com. The paddles are too long for the cargo box so they have to go in the car! The kayaks are tied down to the trailer with several ropes front and rear, so there is a lot of safety factor in the design....I don't worry about the kayaks coming off the trailer! The entire rig works great....when we return from a kayak trip we just back the trailer in the barn and it's ready to go for our next trip. I put a 5" diameter wheel on the trailer just behind the hitch so I can push it around on flat level surfaces. See the pictures.


Comments
Those lights, and all the lighting and trailer wiring products that I bought from etrailer.com, are working great! I used to have constant problems with the lights on my trailer until I switched everything out to the LED lights from etrailer.com! Now they work every time we use the trailer knock on wood!.

Review from a similar Uni-Lite in Trailer Lights


Great item at a great price. Purchased 4 clear with red (2-diodes) to place in my rear step bumper in place of back up sensors for my older truck used as clearance/running lamps.
Fitment was up to me being had to locate rubber grommets to adapt to these smaller 3/4" lights to the 1 1/8" bumper holes.
I would give these 5 stars but for some reason the black wire is the HOT, while any automotive electrical item I be ever worked on the BLACK was the ground! Opposite here and recommend testing them before you hook up like I did then had to reverse wires..
Silly mistake on my part but why is the black (+) and white (-) ???
Otherwise they're bright and add to my otherwise dark OEM tail lights for increased safety. Pic shown is during daylight!


Comments
Still bright and working great. Excellent product.

Review from a similar Uni-Lite in Trailer Lights


Purchased to use as grille lights on my pickup. Specifically chose DOT approved to avoid any possible problems later on. Chose single diode in hopes that the light output wouldn’t be overwhelming. Has made it through the vibrations of driving in heat and snow. Appears to be well sealed and housing holds up to everything the front of my truck has been subjected to in the past year. Would buy again.

Note for eTrailer: thank you for soliciting useful reviews by asking for reviews after a year. It seems like most sites ask for reviews the second you order the product which leads most people to review the vendor instead of the product. I normally don’t leave reviews, but you made this worth while.

Review from a similar Uni-Lite in Trailer Lights


Great addition to the basic, rear brake lights of a camp trailer.
I added these LED RED to the brake/turn function, within the existing, small holes in the rear bumper--much more apparent when stopping/turning.
These sealed LED lights are very common on larger trucks and trailers now. Easy to install and very robust assembly...priced right!


Comments
Always great, tested products from ETrailer. These LED lights did not disappoint...still shining brightly. Thanks!

They are low profile in the day, and very functional in the night with their brightness. I did not expect them to be this good. I wired them as marker lights for my rear fenders.

Review from a similar Uni-Lite in Trailer Lights


I actually purchased these lights to use as a side marker light on my Jeep Wranglers after installing after market fenders. Lights have worked fantastic up to this point


Comments
Thank you for following up. Your email caught me off guard as many companies dont follow up like this however, I truly do appreciate it and commend etrailer.com and of course you for the awesome customer service! As to the lights themselves, I can gladly say that they are continuing to perform exactly as I had expected they would.

Got all my parts expect for one, looks like they couldn’t find the correct light so they just threw a random one in that looks similar.

Plus got told on a previous item it would had shipped many many times over a month period when it never had. Got told yesterday it wouldn’t be in stock till May…


Comments
Oh no! I am sorry that the incorrect light was shipped out. I will have our Customer Service team reach out to assist you.

Review from a similar Uni-Lite in Trailer Lights


Very well built, sturdy and totally sealed against moisture. I installed these into the top of my Haulmark enclosed trailer to act as clearance lights. Installation was a breeze, I just drilled a 3/4" hole with a step bit, wired all five lights together and tied it into the running lights of the trailer's harness. I put the ground against the steel frame. I went a step further and put a bead of clear marine grade silicone around the light to ensure no moisture makes it inside the trailer despite these being a tight fit. As you can see from the pictures, installation is clean and they're very bright, both day and night! I put one on either end, 6" from the sides and the three middles ones are spaced 10" apart. Similar to the clearance lights on a truck, I didn't use a template, just winged it.

Great little running light puck! Easy to install and very bright at night and is even very visible in daylight. Only about an inch in diameter on the outside, you wouldn't think it was much larger from the amount of light they provide.


Comments
Awesome, bright lights. They really blend in well in daylight but stand out at night.

I have purchased lights from etrailer several times and the service and quality have been great. I have purchased lights for my truck and also have used there submersible lights for my boat trailer.
lights have been in service for over a year and still bright as the first day I installed them.

Review from a similar Uni-Lite in Trailer Lights


I ordered these light to be used as accent light on a new lift table for my company. I needed low profile and fairly bright red light to be reflected off our off-white power coat. These little lights out preformed what we were hoping for. The only thing I don't like about them is the instructions say to drill a 11.16" hole. Assembly was WAY too tight at that dimension. So we stepped it up a fraction at a time and found that 17/64" (.73) and 3/4" (.75) were perfect. Even at 3/4" the grommet was snug and water tight. The light had to be squeezed into place but at 11/16" I felt like I was about to brake the light.
Overall I am super pleased with the lights. We added them to the Bill of Materials and we will be ordering them for these new carts.

Review from a similar Uni-Lite in Trailer Lights


Shipping was slow, but I can't complain much considering it was free!

I chopped the fenders on my 2008 Jeep Wrangler, which involved removing the side marker lights. I installed a pair of these DOT approved lights to meet inspection requirements.

As for the lights, they are well-constructed and very bright. Installation was difficult; even after drilling and deburring a 11/16" hole, the grommet barely fit in. I had to put a small amount of grease on the light's lateral surfaces before the light would slide into the grommets.

Overall, I am very pleased with the product. Poison Spyder sells an inferior product at several times the price; I am glad I found these here!

Awesome little light! Very bright! Fits snug in a 3/4" hole. These worked perfectly for my running light project on the air dam. Ordered these on a Sunday, they were at my door on Thursday. Excellent customer service Etrailer! (Side note, the lights behind the grill are 4" round, not the 3/4")

Great customer/sales representative, Michelle! She was awesome! She crossed referenced another number, not exactly a high volume or priced item. But she treated me like I was spending a million bucks. Also, she sent me multiple emails so I could track my package, receipt, and a thank you! All that for about a $10 order. I’ll never buy from anyone else. Thanks etrailer and Michelle.

Love these l.e.d. lights. Had seen exact same lights on a new truck at work and wanted them for my personal truck. Found them here on etrailer at a great price. They are really bright for such a small light and low current draw. Simple, fast install.
