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.

Video Transcript for Optronics Trailer Lights - Utility Lights - UCL50CB Review

Today we're going to be taking a look at part number UCL50CB. This is the Miro-Flex 2-inch sealed LED utility light. It's going to feature a sealed, waterproof design. Optronics is going to put a lifetime warranty on the LEDs. It's going to feature nine of those clear LEDs. LEDs are going to make great replacements for incandescent lights.

They're going to burn brighter, last longer, they're going to be much more efficient. You don't have to worry about replacing the bulbs, and you don't have to worry about the brittle filaments. Again, this is designed to be used as a utility light. It's got the sealed, waterproof design. It's going to feature a polycarbonate clear lens, as well as a polycarbonate white base. Here on the back side, we're going to notice the two-prong connection.

This is designed to accept the industry standard two-prong plug. That's going to be sold separately. To get this mounted, you're going to need to use a grommet or a bracket. Those items are available here on our website, etrailer.com, but they're going to be sold separately as well. Taking a look at the overall diameter here at the back, since this is our widest point of the light, that's going to give us a measurement of 2 inches. The overall depth is going to give us a measurement of about 1 and 1/16th of an inch.

Just measuring that lens portion, right here. The power draw on this unit is 0.013 amps at 12.8 volts. We're going to go ahead and hook it up to our external power source. That way you can see what it looks like with power running to it. We're going to take our two-prong connection and hook it up. You can see here that it does send out nice, consistent light.

What I do want to show you is if you get this and you're having trouble making the connection, you can see there I have my two-prong plug connected, but it's not sending through any signal. That's because I don't have the ground in the right location, so I'd need to flip it over, and then it's going to put through my signal. It really sends out a nice, consistent, bright white light. Again, a clear lens with clear LEDs allows a lot of light to come through. Multi-diode design, it's going to contain nine diodes, so it's really going to optimize our light output. That's going to do it for today's review of part number UCL50CB. This is the Optronics Miro-Flex 2-inch sealed LED utility light. .

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. 683043


Works good for small work light. Bright for the size 575894

Still working great!
Shawn - 10/20/2019



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 543134


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. 474395


Super bright. As usual, George got back to me within an hour. Great service. I will always use these guys 467662


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. 447439


shipped promply-easy to work with. Thanks Karen 409075


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. 403351

Exactly what we were looking for our replacement bulbs. 331645


Awesome little lights! VERY bright! Our ONLY problem is that we ordered the wrong size! Otherwise.....Great price, GREAT service, VERY quick shipping!!! :) 276848

Lights are still working great after a year!
Lisa - 07/27/2017



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. 267648


great as usual.thanks 223812


Bright light but it doesn't have enough flood coverage for backup lights. 179827


Ask the Experts about this Optronics Trailer Lights

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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...
