Optronics MCL63 Series Miro-Flex Red LED Marker Clearance Light 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 Selaed LED Trailer Marker and Clearance Light Installation

Today, we're going to take a look at and show you how to install the optronics sealed myral flex thin line LED trailer marker clearance or ID light. Part number is MCL63RB. Here's what our marker light looks like now. We're going to be replacing it with this nice, clear LED. There's nothing wrong with this one, uses the incandescent style bulb. Which is great, it's just showing some sun shade, over time.

Our customer really wants to update the look of this trailer. Lights are a good way to do that. I'm just going to release the tabs here into the light. It will just pull right out of there. Clean up our connection point. The new light's designed to fit right into that bracket.

You just want to line up the pins behind it, and push it in until we hear it click. That's all there is to it. Let's flip it on to make sure everything's working the way it should. As you can see, it's going to give us a nice, good looking lens. It's clear, there's no sun fade, no cracking, and it gives a nice, full bright light. That will complete today's installation. The optronics sealed myral flex thin line LED trailer marker clearance or ID light.

This is in red. Part number MCL63RB. .

These LED Miro-Flex lights are a proper upgrade. They really look SHARP! My truck is grey, my trailer is grey, I replaced all the marker and tail lights on my 09' 7x14 tandem HaulMark with these and now have better visibility during the day. After a year i still am very happy. I noticed the lights are directional, so if your at the side during the day you have to look at them straight on to see if they are working but thats really not an issue. You have markers on all four sides just for that reason as well as reflectors. I have actually gotten unsolicited compliments from other contractors on the trailer since i got these. 272923

Perfect replacement for my 2004 OEM lights. I converted the in closed trailer to LED. It’s been around a year and everything is just fine. Remember, quality first price second. [base plate A65PB, LED yellow AL91AB, LED red AL91RB] 659313

It appears that this will be an excellent light after I receive all of the additional parts to actually install the lights. I ordered 14 of these lights only to find out after receipt they require the mounting brackets and plug in. Thus delaying the project and incurring freight cost because the order is under the threshold for free shipping. I upgraded the freight to ground only to find out that etrailer didn't have the part of my additional parts in stock. Jury still out on this project. 559531

Review from a similar Optronics Miro-Flex Thinline in Trailer Lights


Perfect fit for my Trails West Sierra II horse trailer rear side marker light. My horses somehow bit off the original and this was the exact same fit. Trailer is the only place I could find these types of lights. Just sad the shipping had to cost more than the light itself 462582

Lights were exactly what I needed to lower the total draw from the 15 running lights on my trailer that kept blowing out the fuse on my Honda Pilot. And they are brighter than the old style. Easy to install - just pops right in. Thanks 436015

Very pleased with the thin Miro- flex side markers. I put them on my 2001 dodge dually and man are they bright. I only wish they offered them in 2 1/2 too. But over all they are well worth buying if your looking for good looking lights on or off. 384016

Review from a similar Optronics Miro-Flex Thinline in Trailer Lights


the lights are very nice (bright) but the bracket housing that they fit in (plastic based) are really not a very good quality. The snaps on each end that holds the light are not all molded the same and I had one defective one that would not allow the light to snap in therefore the first bump i hit the light itself flew out going down the road and was lost. can't afford to keep replacing lights that simply fall out. 669183

Ask the Experts about this Optronics Trailer Lights
Do you have a question about this Trailer Light?


  • LED Version of the Bargman 99 Incandescent Clearance Light # 3499001
  • The closest thing we offer to Bargman 99 Incandescent Clearance Light # 3499001 that you referenced that is an LED would be the Optronics Trailer Lights # MCL63RB. Dimensionally these lights are virtually identical. I attached a review video for this light. For an install bracket you would want the part # A65PB.
    view full answer...

  • Chrome Base Recommendation for the Optronics Clearance Light # MCL63AB
  • Yes, the Chrome Bracket and Single Wire Plug # A67CB that you referenced is the correct base for the # MCL63AB and # MCL63RB that you plan on getting. The reason this bracket uses a single wire is because the light will ground through the mounting hardware. If you needed to run a second ground wire to the assembly you would only need to run the stripped ground wire around the mounting screw that attaches to the side of the base with the ground strap. See picture I attached to see which...
    view full answer...

  • Mounting Bracket Recommend for Running Power and Ground Individually to Thin Line Clearance Lights
  • To use the # MCL63RB and run the ground and power wires directly to it you would need the part # A68P as well. This would allow you to wire up the light without having to ground the light through the mounting hardware. For a bracket you would then want the part # A65B.
    view full answer...

  • Does Optronics Side Marker Light # MCL63RB have to be Mounted a Specific Way
  • Lights that have to be mounted in a specific orientation will have TOP printed on them somewhere which I do not see on light # MCL63RB. The lens is designed to direct the light straight outward so that is likely why it is harder to see them if they are mounted high and you are close to the trailer. A lens design like that found on # MCL75RB would be a little easier to see at steeper angles. I have included a help article on trailer lighting requirements for you.
    view full answer...

  • Replacement Clearance Light for Boat Trailer
  • In order to select the correct clearance light for your boat trailer, you would need to measure the light and know how it mounts. For example, the Optronics Clearance Light # MCL63RB is 4-1/16" long x 1-1/4" wide x 1-1/8" deep and is a surface mount LED light which mounts on industry standard 3" centers. I've added a link to each of our clearance lights for you to take a look at.
