Optronics MCL44 Series LED Marker Clearance Light Dimensions

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.

Great looking lights, easy install, wiring for amber/red lights matches wiring style of trailer. Only downside, is that the lenses crack easily when prying them off, because the seal is so good. If doing a whole trailer, order some replacement lenses as a back-up. Also, make sure to pry the lenses from the middle of the long side of the lens, NOT the ends.

This is a great, overall product. Lights are bright, and can be seen in the daylight. Installers should be careful when snapping lens covers on... They're very snug (they seem almost watertight!) and I cracked two of seven, and had to order replacements. (they do sell just the lenses... but I found out too late.

The site is laid-out very very well. It's easy to find exactly what you're searching for. - My item was exactly as described & I'll be back for more items as I need them. I especially liked the way the order/item was 'tracked' while en-route. I recommend 'etrailer.com' for quality items & excellent customer service/communications.



- MCL44RB1

These items is just what I was needing. Now I don't have to worry about every year when I start checking my trailer to get it road ready, of having to tap the clearance lights and or replace bulbs just to get it road. From the minute I made contact with one of the sales people in customer service of etrailer I immediately felt at ease and confident I was going to be satisfied and get the replacement parts I needed and that being, the LED replacement clearance lights for my trailer. I would surely recommend this company and the service they provide to anyone. I am truly grateful for their assistance and the products they sell.

These 1 wire self-grounding lights from Optronics are exactly what I was needed to match up with original lights on my enclosed car trailer. These lights were a breeze to install, the led's are bright and I am very happy with this product and Etrailer !!!!


Comments
These lights are still working perfectly !!

Quality plastics, snug seal, and I like that the red and amber versions of this light are wired EXACTLY like my trailer: Single-wire, and 2-wire, respectively. I only wish the wires exited through the (unused) recessed center hole like they're supposed to. Will require a little extra work to install, but otherwise good purchase.

I have the best lit trailer in the group. It looks great and they were easy to install.

I bought both this and the amber colored lights. Product is very easy to install. It serves its purpose by being bright enough as a marker/clearance light without being obnoxiously bright. My only negative comment is the packaging. I bought 4 lights and it was packaged with a crumpled packaging paper on the bottom of the box and all 4 lights was just placed on top of it. I think the lights should have been individually wrapped as there were some light scratches on all the lights when I opened the box. Not really a concern of mine as nobody will ever see the scratch unless looked on very, very closely, but people with major OCD might not like it at all.


Comments
Still works.. Only thing I forgot to mention in my 1st review. The entire light assembly is not sealed. The led circuit board is sealed with some sort of hot glueclear silicone but not the whole assembly. I decided to seal the entire assembly with clear silicone can be bought at any hardware store to prevent the inside of the reflector housing from becoming discolored.

I bought this light to start replacing the incandescent lights on my trailer. This store makes it easy to find which light I needed to start this project. And they also carry a better selection, I will use them again.

I purchased these LED marker lights for my cargo trailer to replace the original incandescent markers that were failing from corrosion after only a few years. Since these were the same manufacturer, the lenses are exactly the same - now I have a handful of spares! The marker lights were mounted with the same screws, but I did have to re-drill for the wiring as the LED wire exited the base at a different location. Installation was a breeze, and the LED is brighter, and will hopefully last much longer.

I have an enclosed motorcycle trailer that came with stock incandescent lighting. I like the LED lights because of the reduced power draw and that there virtually indestructable. These replaced the last of the stock lighting. They fit in exactly the same position as the stock ones. They are used as side marker lights towards the rear. So now my trailer is 100% LED lighting and the price was right!

Everything arrived in perfect order and exactly as I was hoping for. I will get these parts installed on our horse trailer soon and will attach pictures once completed. I also will be ordering a few more items for my new pop up once I get it home and see exactly what it needs. Looking forward to fixing that up as well.

Have had these on my 2007 Winnebago Journey motorhome for a year now. We even struck a bird at highway speed which compressed the fibreglass enough to make the light pop off but we never lost it and just snapped it back in place. Would recommend these.

I bought these to replace the incandescent lights that were on my trailer. It matched my old ones perfectly maybe they were the same company i am not too sure. These are bright at night the color is crisp compared to the old lights. The lens has no rubber seal nor is it one whole piece. The leds themselves are covered in some sort of clear epoxy to make it waterproof. There are 6 leds in the middle i wish they had some pointing to the side so it gives a brighter glow but this style is not bad. Good thing about leds is the long life they have so there is one less thing to worry about. Especially towing late night to the race track the people behind me can see me a good distance away with how bright these are compared to the old lights.
