Optronics UCL50 Series Micro Flex 2 Inch LED Utility Light Diagram

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.

2" Diameter waterproof LED utility light adds bright white light to an interior area. Miro-Flex design provides increased light output with a contemporary design. Flush mount with grommet (sold separately). Accepts standard 2-prong plug.


From Customer Service assistance at Optronics in finding the produced need, to ordering through recommended dealer (etrailer), the experience was easy and great. Product arrived a day later than expected but was well packed and in tack. Lites are well constructed and appeared to be of high quality. Installation was quick and problem free. Light output was very bright and better than original supplied with trailer that were replaced several times in 2 years under warranty.
I have high expectations these lites will provide excellent service for many years to come.


So far so good. I'll get some pictures when it hits the street. Used them for back up lights and an older CJ


Etrailer was great to work with!!!


The light fit as me, and one of your technicians, checked everything about it and they were right, I gave them good measurements, of course, but this is not an exact replacement, but it’s pretty darn close


These little lights are pretty great. I tested a couple as soon as they arrive and they are bright and clear. The yellow tint shown in the pictures is not even there. Ordering from etrailer was nothing short of awesome. Sandy helped me buy the right parts; she was cheerful and amazing. Their return policy is what ultimately convinced me to buy from them.


Molly E. found this light in short order when I couldn’t find it online at e-trailer or anywhere else (including local camp/trailer shops.) Hard to locate round LED puck with clear lens. She was awesome to work with and the light was a perfect replacement fit for the original hook-up light on the nose of our Voltage 5th wheel. It’s still burning bright.


The LED lights is well made? Use these on the front of are camper for lighting after dark as a night light. We have used them for a year with no trouble.

The LED lights for still working great!


I often use eTrailer for repair parts, as I did with this purchase. As usual the parts are delivered timely and they work as expected. I haven't installed these lights as my RV is in stroage. They look to be the ones I need. I have never been disappointed when useing eTrailer.


I used this light to replace the incandescent light on my trailer for license plate illumination. Plugs right in, mounts in the 2" grommet. Works great.


I used these to replace the original halogen backup lights on my Ranger boat trailer. One year later, they are still working great and give off as much light as the halogen units. Thanks


Awesome little lights! VERY bright! Our ONLY problem is that we ordered the wrong size! Otherwise.....Great price, GREAT service, VERY quick shipping!!! :)



Lights are still working great after a year!


Bright light but it doesn't have enough flood coverage for backup lights.


Works good for small work light. Bright for the size



Still working great!


Love this company. They back their products and shipping. Got a busted light and they replaced it, no questions asked. They just sent me a new one.

4 stars due to my expectations. I expected the lights to be brighter than they are, but they aren't bad. They light up enough ground behind the trailer to see, bit not so well with tinted window.


received order, installed and works great. Light is powerful, more so than original light installed at rv factory.. Thanks for the help.


We looked everywhere for this light and found it on your site. Delivered quickly and product is just like the pic. Love your e-trailer


Thanks for your follow up request. I'm very pleased with the lamps I purchased from your company. I used them in a garden gnome project as headlamps of the tractor the farmer (gnome) is driving. So even though they have nothing to do with a trailer they served the purpose perfectly. I will certainly let you know of any more projects I need products from you to complete.


Super bright. As usual, George got back to me within an hour. Great service.
I will always use these guys


Exactly what we were looking for our replacement bulbs.


Quit working after about 5 months


shipped promply-easy to work with. Thanks Karen


great as usual.thanks

  • Which 2 Inch White LED Light is Brighter # UCL50CB or # UCL55CB
    The 9 diodes on # UCL50CB are going to be brighter than the 3 diodes on # UCL55CB. So if you are looking for the brighter of the 2 go with # UCL50CB.

  • Power Draw and Lumen Rating for Micro-Flex 2 Inch Sealed LED Utility Light UCL50CB
    Utility light # UCL50CB is rated at 0.013 amps at 12.8 volts. The lumen rating is not available but would be greater than 224 raw and 168 effective output. The exact figure has not been determined by Optronics.

  • Are There Blue Trailer Lights
    The Optronics Miro-Flex LED Utility Light - Submersible - 9 Diodes - Round - 12V/24V - Clear Lens # UCL50CB does not come in blue, though there is a similar light that does have blue LEDs. The Optronics LED Trailer Utility or Hitch Light - Submersible - 9 Diodes - White/Blue LEDs - Clear Lens # UCL09CBB has blue LEDs in the middle, as you can see by the accompanying photo. This is a 3 inch diameter light which is a bit larger than the 2 inch diameter Miro-Flex you asked about. I have...

  • Looking for 2-1/2 to 3 Inch Clear Round Trailer Light
    It depends on what type of light you are looking for. If you want a tail light assembly then it would have to have a red reflector on it to be DOT approved. If you are looking for a utility light (white light) then we do have some available, # UCL60CB or # UCL50CB. As far as just a lens we have some clear ones but they are over 4 inches in diameter.

  • Recommended Bright Back Up Light For A Utility Trailer
    The Optronics LED Trailer Utility Light - Submersible - 3 Diodes # UCL55CB will be 15 lumens, so it can work as a back-up light, but it will not be very bright. However, the Optronics Miro-Flex LED Utility Light - Submersible - 9 Diodes # UCL50CB will measure almost exactly the same (2" diameter x 1-3/16"), but as it has 9 diodes it will be 44 lumens. This is the light I would go with. If you do not already have them, the Right Angle 2-Wire Pigtail # A49PB and 2" Round Grommet # A54GB...

  • White LED Light Recommendation to fit a 3 inch by 2 inch Area
    The best recommendation I could make since we don't have a 3x2 LED light in white would be the part # UCL50CB. This is a 2 inch diameter round white LED that would supply a very bright white illumination. For a pigtail harness to install this light you would want the part # A46PB.

  • Do All LED Trailer Lights Work with 12 Volt Power
    Some vehicles run 24 volts (bigger vehicles like big rig type vehicles) and some older vehicles have 6 volt systems. But 12 volt is by far the most common. The lights you are looking at, # UCL50CB, # MCL-50CRK, and # MCL55RCB will all work on a 12 volt system.

  • LED Utility Light Recommendation in White for Cabinet Light of Ambulance
    The best solution is going to be with a larger size light if you can enlarge the hole you have like with the Optronics LED Backup Light for Trucks or Trailers # BUL11CB and grommet part # A45GB. You'll need to cut the hole out to 4-1/2 inches in diameter but you'll get a really bright LED setup that will work great. You'll also need a pig tail harness as well with part # A45CB. We don't have anything that would fit a 2-1/2 inch diameter hole.

  • Looking for a 2 Inch Clearance Light That Has Clear Light and Clear Lens
    Optronics does have # UCL50CB which is a utility light that has a 2 inch diameter with a clear light and clear lens. This light operates off 12-24vdc, is waterpoof and has 9 LEDs. This lamp is meant to be used as a utility lamp only and is therefore not DOT compliant. To hook this utility light up you will need either the # A46PB which is the 6 inch lead straight plug or the # A86PB which is the 18 inch lead straight plug. The attached picture give you what the light looks like and also...

  • Replacement Clear Marker Light For a Glo-Brite 9500c-88
    While we do not carry the Glo-Brite 9500c-88 you currently have, we do have a light that will work as a replacement for you. From the information I could find on your Glo-Brite 9500c-88, it measures 2" in diameter. For the clear light, you would want the Optronics Miro-Flex LED Utility Light # UCL50CB. This light measures 2" in diameter and should fit in your current grommet. You would also need the 2-Wire Pigtail for Optronics Trailer Lights # A46PB. If you want to replace the grommet...

  • Recommended Rubber Mounted 2 Inch White LED Light for Reverse Lamp
    If you are looking for an oval shape, we have the GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Oval - Clear Lens - Qty 1 # BUL111CB which is rubber mounted using # A70GB. This light requires pigtail # A45CB or 90 degree # A49PB. If you are looking for a round light, I recommend the 2 inch # UCL50CB. This will use the same pigtail, but will use grommet # A54GB.

  • Availability of LED Back-Up Lamp for 2-1/2 Inch Rough Opening
    If you can very slightly enlarge the hole so it's 2-5/16 inches in diameter, I have a grommet mount lamp that will work great for you. The # UCL50CB LED lamp would use the # A54GB grommet and the # A46PB wiring pigtail. The lamp isn't considered a back-up lamp, but unless the vehicle in question is a commercial vehicle that's subject to DOT inspections, it'll work great for you.
