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.


PC-Rated Lights

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and a side marker light.

Video Transcript for Review of Optronics Trailer Lights - Waterproof Amber Trailer Light - OPT78FR

Hi, there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this Micro-Flex LED trailer light. This is a rectangular trailer light that has a sonically sealed, waterproof, polycarbonate housing and amber lens unit that is going to be submersible. So it's gonna be a great option for your boat trailers. This light is PC rated, which means that not only will you be able to see it from straight on, but you'll be able to see it from either side as well.

So it is going to work great as either a side marker and clearance light, or a made-shift turn signal. Because it is PC rated it can work simultaneously as a side marker and clearance light, if you have it mounted probably. So it's gonna be a really good option for you. It does have the micro-flex faceted or reflector design that's going to increase the light output. And it's going to provide that contemporary appearance.

This will mount to the surface of your trailer very easily. The hardware is not included. You will have to provide that yourself. But our connection point here, we do have a three-wire pigtail that's going to have a delfin connector that's going to provide a weatherproof connection. I'm just got this hooked up to a few wires for display right now.

But that will fit right into your delfin connection to make sure that your wiring is gonna be waterproof as well. As far as our dimensions go, this is right at six inches long, might be better if I show it on this side, could be a little bit closer there. So not quite six inches. I'm gonna call it about five and three quarters. And then our height, we're looking at right about two inches.

And then our depth, I'm gonna say it's right about just over one and a quarter of an inch deep there. Our mounting holes from center to center are gonna be we'll call it four and seven eight of an inch, just shy of five inches. There are 16 diodes on this light. And those LEDs are gonna be a great option, especially if you're looking to replace an incandescent light. They're more efficient than incandescent lights. So they provide more light with less power draw. They last about 50 times longer, because they don't have the brittle filaments in there that require you to replace them. So these LEDs do have a lifetime warranty. So because this is a three-wire system, we can have it hooked up to constant running power like I have it here. But then if you we're to use it as a turn signal, you also have that option, where those lights will get a little bit brighter as you're turning and that turn signal is synced to it. So overall gonna be a really nice option to switch out a trailer light on your boat trailer. It's not gonna have to worry about getting wet or being submerged. It's gonna hold up well for you, provide that nice, bright light even at night. To demonstrate that, I'll turn off the lights here in my studio, if I can find my night switch. There it is. So it's gonna provide sufficient light for any motorists coming up behind you to know where you're at and that sort of thing. So you're not gonna have to worry about visibility in low light conditions. So again, really nice option to switch out your light on your boat trailer or any other trailer that you're needing a new amber light for. That's going to complete our look today Again I'm Michael with etrailer.com. Thanks for watching..

Review from a similar Miro-Flex in Trailer Lights


This fixture was the exact replacement for my 2011 Trailmanor 2720 trailer. The manufacturer had moved to a more modern looking fixture. I was even able to use the old chrome piece from the old fixture to keep a uniform age look. I installed a wireless rearview camera and needed a new fixture and its longer wires to make everything work. May look a little strange, but it works like a charm. E-Trailer service was excellent as usual.


Comments
The fixture is still hanging in there. No issues.

Review from a similar Miro-Flex in Trailer Lights


These side markers (both red and amber LED) are great for my 12' trailer. They have 3 LEDs (you can also get 4), and their size is perfect for a small trailer. The LED's are really bright, not only at night, but also during the day, so they are easily seen. I especially like the fact that they are sealed, so there should be no water intrusion problems in the future. I have included a few pictures, the first showing the round LED brake/turn/running/reverse lights (that I had purchased earlier from etrailer) with the red side marker mounted vertically on the outside. The second shows a side view of the red side marker light, and the 3rd picture shows the side marker mounted to a small piece of 1" X 1" x 1/8" aluminum angle which I painted black to match the mounting frame of the round LED lights. I mounted the LED side marker to one leg of the aluminum angle, then mounted the other leg with 1" standoffs to two holes already present on the black mounting frame of the round LED light. Although all the lights are sealed against water intrusion, I decided to mount them on each side of the trailer at the top of 2 PVC pipes, about 36" long each, where the lights would not be exposed to immersing in water when launching/retrieving a boat.


Comments
After a year, the lights are still bright as ever. One of them even survived being drug down the highway for 100 yards when the PVC pole it was mounted to came out of its holding fixture!!

Review from a similar Miro-Flex in Trailer Lights


I installed these lights in a [email protected] teardrop camping trailer. The grommet would not work on this style trailer so I installed the lights using a silicone adhesive the same as the original Peterson lights. eTrailer delivered them in the same timely manner I have come to expect from them and the LEDs were easy to install. These lights are blindingly bright - simply amazing. I had rear lights with 1157 bulbs which I had upgraded to 2357 bulbs and equipped the tow vehicle with a powered converter but the light output was dim by today's standards. These lights are twice as bright on running lights and about 4 times brighter on the brake/turn signal elements. The thing we all fear when towing is being hit from behind by a driver that does not see our running, brake or turn signal lights in time. I know these lights will vastly improve the safety and visibility of our trailer. Thanks!


Comments
These lights are great and you have sold a number of them to our friends now.

Review from a similar Miro-Flex in Trailer Lights


This product worked great replacing my old dry rotted, screw stripped bulb tail lights(approximately 5"x5.5") on my boat trailer. In fact, they fit in the tail light mount better than the old light. The installation couldn't have been any easier. Special thanks to Cailee V for getting me setup with these tail lights after I ordered a different tail light on my own that didnt work for my project.

Review from a similar Miro-Flex in Trailer Lights


These are a perfect upgrade on my jet ski trailer which was constantly burning bulbs maybe because the lights were not watertight. No amount of dielectric grease prevented it. These were easy to install. They are watertight and are twice as bright as the old ones. Great customer service! I highly recommend the lights and etrailer.com!


Comments
They are still working well and could not be happier. They are bright and a perfect upgrade. I had the marker lights go out briefly but only due to a dirty ground. Other than that, perfection! Thanks for following up! That’s ideal customer service.

Review from a similar Miro-Flex in Trailer Lights


Great little lights, and very bright as well. They have been installed on a trailer and submerged many times since installed, and still work great!! Can't beat LED's for brightness and, hopefully, longevity!!! Attached is one picture of the overall trailer, and a closeup of the amber side light. I also have 2 red sidelights that are mounted above water at the rear of the trailer, and they are still working great as well.


Comments
These side lights are bright LEDs and the amber ones have been submerged more than once-and are still working great!! The red side lights are mounted high on the vertical poles, so do not get submerged in water. However, all 4 side lights have been exposed to the weather for over a year, and all are still burning bright!! These are cool little LED lights!!

Good value, good lights for the money. They are still holding up after a year, I would recommend them. etrailer is a great company, I've been using them for several years now and have never been disappointed with their parts and service.

I got these because the original ones were a single bulb theses are much brighter. I also got a 7pole to 4 pole adapter my old one got squashed I went to 5 different places and no one had it checked on etrailer and there it was I ordered it and it was in my hands in less than a week as you see I taped it together so I never have to search for it. one other thing I got was a chrome led license plate light I had replaced mine with a original plate light from the trailer company twice and they keep breaking I think it was because they were black and you couldn't see it with this one being chrome it sticks out and being led it is much brighter and it cost less than the original one

Review from a similar Miro-Flex in Trailer Lights


I received the lights and tested them; they worked fine. They are destined to be used on a car, not a trailer. Side marker lights for cars/trucks are rare now because they are incorporated into the front and rear light assemblies and rap around the vehicle. The lights I ordered from you are the only ones I could find that had a hole-mount pattern wide enough to clear the metal cutouts, under the old lights, in the fenders of my car. I'm glad you have a huge selection to choose from. I'm not sure when I'll get around to installing them. The car is undergoing a restoration for the third time. All I know is the next time I remove the stock side markers, they will shatter. Few trim parts are available for this car these days and nylon snap-in mounting tabs dry rot and break after a couple of decades. I bought this little car new 26 years ago and took it around the world with me before I retired from the Air Force. I attached a picture of it from the last touchups 7 years ago. It won't quit running so I keep giving it new birthdays. This little rat car has become a part of my DNA. 1991 GEO Tracker 4x4. Original owner.

The Miro-Flex LED Combination Trailer Tail Lights were easy to install with a simple wrench. The mounting-nuts and -bolts that come with the lights are stainless steel which I expect will last.


Comments
1.5 years installed and still going strong. No cracks, leaks or electrical problems. Im happy that I installed these lights on my trailer.

Review from a similar Miro-Flex in Trailer Lights


Bought these to replace all of the single wire, ground to the trailer type lights that were on my boat trailer. I bought the amber, red and white lights for the various positions I needed them in. They are bright and work very well. For mounting hardware, an 8-32 machine screw fits just right. Something to be aware of, they say it’s a flush mount, but it’s not with the wires sticking out the back of the light. Instead of drilling a relief in my trailer, I opted to use some aluminum cable stops as standoffs. See pictures to further explain. Worked great in the end. These are quite bright for marker lights and and perfect for what I wanted. ETrailer has prompt shipping as usual.

Definitely a major upgrade from the single bulbs that finally went out on my old trailer. Simple as can be when it comes to install them. I did have to run additional ground wires to get to get lights to work when the parking lights are on. Could have been due to the fact my trailer is a tilt trailer? No big deal just a heads up if anyone else is having the same problem. Pictures shows them with parking lights on and brake lights. They're bright that's for sure!

These lights are of very good quality and are really bright. I use them on an early 70's Bronco for the front turn signals. Day or night, they are distinct and unique and best of all, . Definitely visibly on during the night AND the day (this can be seen in the photo taken on a Snow day, bright, while half way out of my garage). Great price for a great product


Comments
The LED lights are great. Im very satisfied with them. They have held up well and work like a charm with a distinct look to them as well.

Super fast shipping! Ordered on Saturday with etrailer's free shipping option and received my order on Tuesday. Thanks! The lights appear to be of high quality. Comes with all necessary hardware, but I used butt connectors instead of the supplied come shaped connectors. Lights are MUCH brighter than the halogen models they replaced; both tail and brake/turn. You could barely see the old taillights in the day time, these are far superior!

Review from a similar Miro-Flex in Trailer Lights


These bright and waterproof little lights are wonderful. They draw only .5 watts (ie so little they will probably not make a difference to any auto, RV etc lighting circuit). I used them to enhance the dim stop and turn signal on my RV. The plastic lens were fogged and the voltage kind of low (a 40' RV has a lot of voltage drops) but these little LEDs shine bright and were a LOT cheaper than trying to replace the existing fixtures. I just wired them in parallel with the existing light bulb. So now I have a bright stop light and a built-in spare (the existing bulb could burn out and the LED will keep working). The photo shows how I did it

These lights fit my 16 ft dove tail tandem axle trailer perfectly and illuminates the license plate exactly as advertised, have no trouble hauling loads after dark. Highly recommend.

The original tail light fixtures on my landscape trailer were of , shall we say, less than acceptable quality. These are good quality fixtures. Easy to install and they fixed my problem.
