Optronics Trailer Lights - MCL17RB

Highlights

  • Reliable In Any Weather: Sonically sealed, waterproof housing keeps water out so LEDs stay protected.
  • Fewer Replacements Needed: LEDs last 50 times longer than bulbs and draw just 0.047 amps at 12.8V.
  • One Light, Two Uses: Works as a clearance or side marker light when properly mounted.
  • Brighter, Modern Look: Miro-Flex reflector boosts light output for better visibility.
  • Clean, Finished Style: Snap-on chrome bezel gives a polished appearance.
  • Simple 2-Wire Hookup: Power and ground wires can connect either way for easy install.

Features to know about

Brighter and More Efficient Lighting: 3-Diode LED Output

Older incandescent lights fade fast and draw more power than they should. This red Miro-Flex LED light uses 3 diodes that shine brighter while using less energy—just 0.047 amps at 12.8V. With LEDs that last up to 50 times longer than traditional bulbs, you’ll get reliable illumination without worrying about replacing burned-out filaments or worn sockets.

Keeping Water Out for Good: Sonically Sealed and Submersible

If your trailer ever sees rain, road spray, or even the boat ramp, this light is built to handle it. The housing and lens are sonically sealed into a single waterproof unit, making it fully submersible. No water intrusion means no corrosion or short circuits—just dependable lighting every time you tow.

Cleaner Look and Easier Install: Surface Mount with Chrome Bezel

Mounting this light is simple thanks to its surface-mount design with a distance of 3-1/8" between holes (center on center). The snap-on chrome bezel gives the finished look a polished touch without extra effort. It connects with a 2-wire setup—either wire can serve as power or ground—making wiring straightforward during installation.

Better Visibility Where It Counts: P2-Rated Beam Pattern

Staying visible on the road matters, especially at night or in low-light conditions. This P2-rated light produces a 45-degree beam to either side of center for 90 degrees of forward coverage. That makes it ideal for use as a clearance or side marker light when properly mounted, helping others see your trailer clearly from head-on angles.

Built for the Long Haul: Durable Design with Lifetime LED Warranty

Measuring 4-3/16" long x 1-3/8" wide x 3/4" thick, this compact oval LED light is DOT compliant and made to last. The LEDs are backed by a lifetime warranty, so you can count on them to keep shining bright for years of towing without fading, cracking, or giving out.

Great service and delivered 3 days early!
Have
ordered parts from etrailer several times and ALWAYS had good results
The parts I ordered this time was cheaper than ANY other web site and fast delivery
I live in rural Montana so can't get some parts local
I recommend etrailer every time



by:

Exact match with my original lights. Works great.



by:

These guys Rock! Ordered one day and 2 days later I had them. Could hardly have driven to town and tried to locate the lights myself before these arrived.
Great lights! Look good, and easy to install.



by:

This light was of better quality than expected. I replaced dim/faded 50+ year old original lights after some consideration of "originality vs safety" and safety won out. More attractive and a brighter light, great upgrade.

7.16.15 - GEORGE...YES I AM IN RECEIPT OF THE MARKER CLEARANCE LIGHT (RED MCL17RB AS SHOWN BELOW) FOR OUR TAILMANOR ELKMONT 2010 TRAILER...AFTER VISITING SEVERAL RV STORES INCLUDING WHERE THE TRAILER WAS PURCHASED FROM THE ATTEMPTS WERE UNSUCCESSFUL...THEREFORE BY LUCK WHILE ON VACATION I FOUND THE NEEDED PRODUCT AVAILABLE FROM YOUR COMPANY WITH PERFECT DELIVERY SERVICE...THANKS & BEST



by:

Good looking product.



by:

Nice looking tail light that I used to replace faded upper clearance lights on the rear of the fifth wheel. Excellent fit.



by:

It might be possible to give 5 stars but after purchasing all the products about a year ago, my little fiberglass trailer is not even close to being ready. All the lighting is hooked up and they all seem to work, so that's a good thing. The other products that I purchased have not been installed yet.
I would like to mention how pleased I am with e-trailer videos showing everyone how their products look and how they're used. Keep it up, I am a happy customer.

Order what I thought was similar lights for my flatbed but was very wrong. These lights here are some of the best quality and exact fit and bright lights on the market. Definitely will continue to receive my business!!!

One light turned into 9! These lights are worth every penny! Good quality and very bright. I have them on my cm flatbed and couldn’t be happier. Definitely gonna be my go to light from here on out!



by:

Shipping was fast, lights were easy to install and look great, really bright at night. The "bling" to top off paint-n-seal update we are in the process of doing on our 1983 travel trailer. The new LED's make the camper look good, friends thought we got a new one. Highly recommend them.



by:

Nice looking products always happy to deal with you people Thanks again



by:

Very classy. Great product.



by:

Thanks they look great.



by:

I’ve never had any issues with my etrailer orders. If I do have any questions, their staff is more than helpful.



by:

Exactly the product I needed at a reasonable price. Shipping was fast and product arrived without any issues.



by:

This was a direct replacement for my 2016 Gulfstream BT Cruiser 5210. Etrailer has fair prices and cheap shipping. They keep you updated with order and shipping process. First time using their website and it was an awesome experience.



by:

Needed a rear clearance light for our 2016 Tiffin 40AH Phaeton and etrailer.com gave excellent service, fast shipping and the product was as described and worked perfectly.



by:

You guys are the best!!]
Thank you

Love working with etrailer. Good people with a fair price. never been disappointed

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



by:

Exactly what I use now. Easy to replace except for the motorhome height.



by:

Exact replacement! Worked perfectly.



by:

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.

The fixture is still hanging in there. No issues.

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.

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!!

  • Replacement Trailer Clearance Lights for GloBrite 122r/122y
    The globrite 122 in red or yellow/amber are 3.75 inches by 1.70 inches from what I can find online. We do not have a direct replacement, however the closest dimension we have to replace them is 3-1/2 by 1 inch. I recommend the # MC68RB and # MC68AB. If you want to go larger, then I recommend the 4x 1-1/2 inch LED # MCL17RB and # MCL17AB.

  • Solution for Replacement Side Marker Light for Glo Brite 9823R-88
    Hi Cecil; is this light round or oval? I was able to find both when I searched for 9823R-88 so I can't be sure. I don't think we have a direct replacement, but if it is an oval light you could use one like the LED Trailer Clearance or Side Marker Light with Reflex Reflector # 328-K-52. This light measures 4" long x 1-1/2" tall x 1/2" deep. Some appeared to have a chrome bezel like the # MCL17RB so that is another option measuring 4-3/16" long x 1-3/8" wide x 3/4" thick.

    That is becoming a problem with more and more trucks these days. Some folks like to add the Blue Ox 1/2" Quick Link for Safety Chains part # BX229-0512 to the factory connection point to attach the safety chains to or you can add new hooks to the trailers like the Buyers Products 3/8" x 35" Class 4 Trailer Safety Chain w/ 1 Clevis Hook part # 337BSC3835 which allows you to connect to the factory connection points.

  • How To Charge Trailer Battery On Dump Trailer Using The 7-Way Trailer Connector
    You will want to use a circuit tester like part # PTW2993 and check the # 4 terminal on the back of the 7-way trailer connector on your trailer for power. This is the 12-volt power terminal so there should be power to that terminal. You will need to run a 10-gauge power wire like the, # 10-1-1, from the # 4 terminal (12 volt) on the 7-way trailer connector on the trailer to the positive terminal on the trailer battery. This will allow you to maintain a charge on your trailer battery,...

  • Dump Trailer Battery Goes Dead Very Quickly
    I'd recommend checking the wiring of your break away system if you you're using your main trailer battery to power it. A short in that system could certainly drain down the battery over time. I've linked you to a help article that explains how a break away system should be installed.

  • Dump Trailer Battery Does Not Stay Charged
    There might be something in the wiring that is damaged or pinched causing a short that is discharging the battery. Inspect the wiring and fix any problem areas. Also make sure that the vehicle and trailer side connectors are clean and free of corrosion inside where the wires attach and outside on the pins. At best trailer wiring can provide a maintenance charge to a trailer mounted battery but it can't charge up the battery. This is because the wiring is too small and most vehicle alternators...

  • Should I Unplug My 7-Way When Raising my Dump Trailer
    I would recommend you unplug the 7-way before you activate the dump feature of your trailer. A lot of times if you leave the 7-way plugged in while dumping your trailer it will short out the 12 volt accessory circuit.

  • Can a Trailer Battery On Dump Trailer Be Charged Using The 7-Way Trailer Connector
    The issue is that trailer wiring is too small and vehicle alternators are rarely strong enough to push back the amperage needed to charge up a trailer mounted battery (unless it is a small breakaway system battery). The amount of power sent back is only enough to keep the battery at the level of charge it is currently at. Having the 12 volt circuit connected to a 12 volt trailer battery will not over charge it because it cannot charge it up so no worries there. When you have access to...

  • How To Charge Trailer Battery On Dump Trailer Using The 7-Way Trailer Connector
    You can provide a maintenance charge to the trailer mounted battery on your trailer via the 7-Way trailer connector's 12 volt circuit. But the wiring in that circuit is too small to handle the amount of amperage needed to charge up the battery. It is also possible that the alternator on the truck is not strong enough to push back that much amperage even with a larger wire gauge. So if you connect a wire from the 12 volt circuit to the battery on the trailer it will provide a maintenance...

  • Solar Battery Charge Kit Recommendation for Golf Cart Battery Bank Wired in Series
    The OptiMate Solar Duo Solar Charging System with Controller - 20 Watt Solar Panel # MA79JR would be a great choice to give your golf cart's battery bank a maintenance charge when it's parked. It can put out a charge of up to 1.67 amps which would do a great job keeping them topped off. Since your 6 volt batteries are wired in series and have an output of 12 volts this would wire to them also in series to match this.

    The Miro-Flex LED Clearance or Side Maker Light w/ Chrome Bezel - Submersible - 4 Diodes - Red Lens # MCL19RB and Amber Lens # MCL19AB prices change as the manufacturer determines. This is sometimes a material cost and other times is the basic supply and demand equation that doesn't have an easy formula.

  • Troubleshooting Trailer Electrical/Brake Controller Problem on Trailer Towed by 1999 Chevy Suburban
    Have you tried towing the dump trailer with a different vehicle? This would pretty quickly tell you if the problem exists with the tow vehicle or the trailer wiring. If the trailer does the same thing with a different tow vehicle, then you know the problem lies in the trailer wiring. At first glimpse, I'd be inclined to think that the problem you're having lies in the way the trailer connector on the trailer is wired. Please refer to the trailer wiring FAQ article I've provided to confirm...

  • Charging 4 Deep Cycle Batteries Running a Power Inverter with Fridge Plugged in While Traveling
    What you can do is connect the batteries that power the inverter directly to the starter battery on the truck or even an alternator in your 2018 Ford F-450. Keep in mind though that when multiple batteries are connected together it takes a long time to charge all of them up. Instead of using the batteries you could attach the inverter directly to one of the truck batteries so that it will get constant power without depleting the truck batteries. This will allow you to keep your 4 deep...

  • Using a Trailer Tail Light on a Cargo Carrier
    A clearance light like # MCL17RB will not provide you the separate running, brake, and turn functions. It will stay on all the time your running lights are on. Another option instead is to use a strip light like # STL59RB. It will provide all of the functions however if you just install one it will flash regardless of which turn signal you're using. You can install two, one on each side of the cargo carrier if you'd like. You'll also need to install a 4-way connector on the carrier...

  • Can a Trailer Battery On a Dump Trailer Be Charged Using The 7-Way Trailer Connector
    First, a trailer battery cannot be charged up from the 12 volt circuit on a 7-Way connector. The 7-Way can only provide a maintenance charge which will keep the battery at is current charge level. It is possible that the battery is back feeding when the truck is turned off and the trailer is still connected. You may also need to increase the size of the wiring. Wiring that is too small a gauge may not be able to handle the power draw. A short circuit or corrosion in the trailer connectors...

    Whether you are talking about the 12 volt power wire from a 4-Way powered converter or the 12 volt circuit from a 4- to 7-Way adapter, such as # 37185, they both connect to the vehicle positive battery terminal. It sounds like you are talking about the 7-Way so for it you will need a 40 amp circuit breaker, # PK54540, and enough wire, # 12-1-1, to reach from the front of the vehicle to the rear. You would change the number in the quantity box on the wire page to the amount of feet needed....
