Optronics MCL17 Series Miro-Flex LED Marker Clearance Light with Chrome Bezel 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.


P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL17RB Review

Today we are going to show you Optronics Sealed Miro Flex Mini Star LED Side Marker Light part number MCL17RB. The lens is sealed and waterproofed against the housing of this light. Inside are 3 red LEDs that draw a total of .047 amps at 12.8 volts. The LEDs themselves are covered by a lifetime warranty from Optronics. The light also has a snap on plastic chrome cover. The light utilizes a 2 wire design meaning you have one wire lead for ground and the other for power. Now we are going to hook the light up to a power supply so you can see how it looks. Connect one of the wire leads to our ground and the other to power. Hold the cover in place. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics Sealed Miro Flex Mini Star LED Side Marker Light part number MCL17RB.

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. 412668


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!!

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. 666854

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. 641894

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. Vic 366254

Ask the Experts about this Optronics Trailer Lights

  • Using 7-Way Trailer Connector 12-Volt Accessory Circuit to Maintain Battery on Dump Trailer
    If you have read our previous responses regarding the use of the 12-volt accessory circuit from the 7-way, then you know that the circuit can be used to maintain, but not charge a depleted trailer-mounted battery. We typically recommend using a battery charger like the # CTEK56353 CTEK Universal Battery Charger to recharge a depleted battery. The 12-volt accessory circuit should already be fused (or if the 7-way was installed aftermarket, protected by a 40 amp inline circuit breaker...

  • 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...

  • Battery Solenoid Recommendation for a Trailer Battery Charge Wire to Prevent Battery Drainage
    We have a solenoid that will do exactly what you are trying to do. You would want a Tow Ready Battery Isolation Solenoid # TR118665. You would run the keyed power source to the middle terminal and then splice the other terminals inline with your 12 volt power charge circuit. In order to find a good circuit to use I would recommend you find an accessory that only gets activated when the key is on and then tap into the power side of that circuit. On my car I used the power antenna wire...

  • How to Prevent Trailer Dump Battery Overcharging From Truck Battery
    The 12-volt accessory power circuit from your 7-way trailer connector is limited in how much power it can deliver to your dump trailer's battery by the alternator's output and the small gauge wire that's typically used to power the circuit as well as the distance that the power must travel. The accessory circuit can be used to maintain a charged battery, but it does not have enough grunt to charge the battery once it's been discharged. Using shore power and a battery charger like the...

  • 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...

  • 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...

  • 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...

  • How To Charge Trailer Battery On Dump Trailer Using The 7-Way Trailer Connector
    You will want to use a circuit tester like part # 40376, 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,...

  • 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...

  • 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.

  • 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...

  • 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.

    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.
