Just wanted to let you know that the Optronics Miro-Flex Trailer Lights are working great!! Much brighter and more visible that the basic lights I replaced! Hope your business is doing well through this Covid crisis!! Thanks for the communication.


Comments
Still Outstanding

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 Work 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 Work 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.

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.

easy install, love the water proof sealed nature of the lights, this is my third set of lights in 18 years, and hopefully the last. whoever designed that mounting system was right on the money with it.

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!

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 Work 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.

My led light failed within 1 year. etrailer is probably the only retailer that requires me to pay ship back a defective part. I have found that Optronix lights can be purchased on [online store] Shipping is faster and free. Returns? No problem.

Great trailer light! Well built, fits the trailer like a glove. No issues after a year of putting it in and out of the water on my boat trailer. Bright too.

Another year without issues, great product, wouldnt hesitate to buy again. Etrailer is an excellent seller.

Good light, didn't know I had to buy the plug and mount for it separately. The light seems water tight and bright!

Review from a similar Miro-Flex in Work 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!!

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.

I ordered a cheaper version of these lights and they lasted two trips down the boat ramp. I decided to up grade to these higher quality lights for my boat trailer and I have had only great results with no problems. They are water proof and highly visible in the day and night time. Get you a set you will not regret your purchase.

GREAT Ive had no problem with these lights. They have been in the water hundreds of times and are still in great shape.

I put these on the side of a 39 foot travel trailer mostly for the people next to me while towing. They are bright and useful. I do not care for the fact that they light up when the brakes are applied. Other than that they are all good.

Ask the Experts about this Optronics Work Lights

  • Recommended Brightest Interior Utility Light Replacement
    The Miro-Flex LED Utility Light - 12 Diodes - Round - Clear Lens # OPT57FR would be a good choice for an interior replacement light for your trailer. Although the number of diodes does not necessarily indicate brightness, this has the most of any round utility light we have. The light measures 4-5/16" in diameter and is 2-3/8" deep. If you want to mount it flush you will also need the Rubber Grommet # A45GB. From what I have found it looks like the Peterson has a single wire installation....

  • How Many Lumens Does The Optronics # BUL43CB Light Have
    When it comes to The Optronics LED Trailer Utility Light - Submersible - 10 Diodes - Round - Clear Lens # BUL43CB, Optronics uses Candela rather than Lumens to measure the output of their trailer lamps. 1 candela equals 12.57 lumens. This light has 310 candelas so that equals 3,896.7 lumens. To finish the installation you also need the pigtail, # A47PB or the mounting grommet # A45GB. I attached a review video link below.
