Optronics MCL75 Series LED Marker Clearance 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.


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.

These guys are good,we build a few trailers in our shop, & these guys have the inventory, you get it fast & you can get them on the phone, we need more outfits like this to do business with! Thanks Guy's--

I bought my Haulmark 12'x6' Enclosed trailer used a few months back. The trailer was in good shape but the sun faded out the marker lamps. Since I use the trailer as a landscape equipment trailer I'm usually not working at night but now with the daylight savings hour change I find myself getting home when it's dark and now those faded lamps were bugging me. Since I've had great experience in the past with etrailer.com I decided to take the plunge and change out the 14 marker lights to their LED versions...Wow what a difference. Not only are my lamps no longer sun faded but they are bright! Definitely was worth the money and the installation was quick since they simply snap into place.
Thanks,
RAM

I decided it was time to repair the lighting on a 15 year old trailer due to several being broken, and the rest being very faded. I spent quite a bit of time on etrailer comparing options I finally settled on the 4 diode led's. I was excited to see the difference but was ultimately dissapointed with my decision to swap out the old incandescent with more costly led's as the new led lights put out significantly less light. As u can see in the pictures I did the passenger side first, then I took pics halfway thru. If u look at the driver side with old lights it has alot more light even though it only has only 2 working lights, compared to the 4 on the new side! In the front shot u can see the old on the right is casting 10 times the amount of light on the ground. On the plus side at least the orange is now orange, and the red is red instead of almost clear.

I will say the shipping was very fast, and the the customer service was awsome as always.

ordered to replace the faded lights on my trailer, fit perfectly. LED will reduce the draw on my light switch.

These made swapping my horse trailer over to led lights a breeze! Arrived quickly and as usual great customer service from etrailer Staff!

Still working great !!!!

Right product. All worked. Project comp leted.

Oh my, was all a Twitter when they arrived. This was recommended by members from an RV club. I am replacing my old markers with led. First thing I noticed was the wire connection was um, not what I expected, but could work. Then I got your email, sweet. I watched the install video, oh pooh. These snap in a metal bracket, waaah, got no stinking bracket, I be old school, what a twit.

So, my question I guess is, can I buy these brackets for this light? I like the snap in place idea, the original is mounted with screws and prone to leaks. It was an oops getting these but, now that I learn more about them, I like them better.

These LED clearance lights are a great plug-in replacement for the original lights on my Featherlite horse trailer. Much brighter, which is safer.
Great service from eTrailer, ordered on Monday, received on Wednesday.

Still working great, bright lights all around.

Easy to install. Super bright at night and just as good during the day! Best prices hands down!



by:

Lights are nice and bright. Usually LED lights have wired with the correct polarity but it was a pleasant surprise to find that they can be installed either way. Made replacing the old light as snap as they fit right into the old fixture



by:

Great replacement lamps! Lightening fast shipping! Great customer service!



by:

I purchased LED lights to upgrade the lighting on my utility trailer. The lights exceeded expectations in regards to quality and I was very happy with the speed at which I received them. I have just purchased an additional used trailer and will be upgrading that one as well. You can expect another order from me soon.

EXACTLY as advertised. I called to place my order and was VERY impressed with the customer service 'attention to detail', quick product delivery, and product quality. Without a doubt, I will be ordering from etrailer.com in the future!

After a year, the lights still work like new!



by:

The items I ordered came quickly after I placed the order. Replacing the old lights with the new LED lights was easy and it made a big difference in making the trailer easier to see not only at night but seeing the brake lights in the daylight hours. The roof hatch was a easy replacement for the original one. I know the metal one won’t crack and break like the plastic one that was original equipment. After investing in a trailer to haul the hot rod that has taken years to build, make sure the other guy that’s not paying attention can see you and your investment



by:

Lights and light bases arrived very quickly and were just what we needed. The price was excellent and the service also number one. Thank you and even though we don't want to be ordering things to repair our trailer it is comforting to know that you are there to provide them.

As I stated for the lights the bases were a perfect solution to the old bases and with the new lights that just snapped in we were back in business.



by:

This light is just what I needed to replace my 6 year old blinkers on my custom truck. You shipped it to me just as planned. Thank you



by:

Excellent products. These lights work perfectly, are rugged and seem to last. The license plate lights are super bright so law enforcement have no problem reading the plate which avoids unnecessary stops. The lights are directs replacements as well so no modifications needed. Great products. I recommend etrailer to many of my friends and colleagues.



by:

Great replacement parts for my enclosed box trailer that was damaged in the Camp Fire in 2018. The trailer held up pretty well but the marker lights, tail lights and fender lights all melted during the fire. These were perfect replacements and mounted very easily.

  • What is Difference between Miro Flex and Thin Line Optronics Clearance Lights
    The Miro-Flex part # MCL63AB and the Thin Line part # MCL75AB are both very similar. They essentially are just visual differences for the lens. The Miro Flex has more of a Euro style look where you can see the diodes and the reflective base in the light whereas the Thin Line has the diodes obscured. Both would work well and I would recommend you pick which you like the appearance of more.

  • Can Optronics Thin Line LED Trailer Clearance Lights Fit Base Of Lights On Snowmobile Trailer
    I was not able to find the truck Lite 2303 or 2294 lights on their website. You may want to consider replacing most if not all of the incandescent lights on your snowmobile trailer. Since LEDs draw about 1/10 of the power, you can certainly get the draw down a lot more than what you are doing now. We do not have a converter box for a 10-amp load as you described. The # MCL75RB and # MCL75AB lights measure 3-15/16 inches L x 1-1/4 inches W x 7/8 inch D. and require the black base, part...

  • Would Sealed Thin Clearance Lights part # MCL75AB Fit a Horse Trailer
    The Sealed Thin Clearance Lights part # MCL75AB that you referenced would work great for you. They have a universal style installation so they would work well. You will need a mounting bracket for these though. For that you would want the part # A65PB. I attached an install video for this light for you to check out as well.

  • Power Draw of Optronics Trailer Clearance/ Marker Light # MC65AB
    According to my Optronics representative, the Optronics Sealed Trailer Clearance and Marker Light, part # MC65AB draws a total of 0.6 amps at 12.8-volts. An LED version is also available, part # MCL75AB which draws a fraction of that, 0.06 amps at 12.8-volts. Either lamp is used with a base, part # A65PB in black or # A67CB in chrome plated plastic. The lamp base has a single power wire, and picks up its grounding connection by its mounting hardware being connected directly to the trailer frame.

This may require some additional work because you will have to route a wire somewhere for the ground but it will work out just fine.
