Video Transcript for Optronics Trailer Lights MCL11AKB Review

Today were reviewing part number MCL11AKB from Optronics. This is a Sealed Uni-Lite, its a Mini LED Side Marker and Clearance Light with Recessed Grommet Mount and Two Amber LEDs. Here is the recessed grommet mounts, as you can see and thats going to push into the hole that youve droled for the light installation. The hole needs to be 11/16 of an inch in diameter. Put the grommet into the hole and then push the light into the grommet, like that. Its a very snug fit because your hole is 11/16 of an inch in diameter and the light is of an inch in diameter, so it will be a tight fit, which is good.

It is waterproof, you wont have any leaks. You have a two wire design, white is your ground wire, black is your 12 volt or power leak, lets plug this into our portable power source.First on attaching the ground wire to the power source, the ground wire is white. Remember that it should be installed on a clean unpainted metal surface. Now Im going to connect the 12 volt and we can turn off our over head light, turn on the power source and I can show you how this work. See you have a very nice strong amber light.

You have two amber LEDs in there with an amber lens cover. Its a very clear light, its agood marker. What would look especially nice I think as if you have a whole roll of this. Ive seen that on some trailers and it looks really cool. Now we can turn off our power source and turn off our turn on our over head lights I must say.

When this is installed properly at a 45-degree angle, then it is considered PC-rated, which means it will serve as both of clearance and the side marker light, but it has to be installed at a correct 45-degree angle for it to qualify as PC rating. It is prove by the Department of Transportation and there is a lifetime warranty on the LEDs. The light itself is of an inch diameter as I said and it is 15/16 of an inch deep, so almost an inch, thats for the light itself, not with the grommet, so like that. There you have it for part number MCL11AKB, the Sealed Uni-Lite Mini LED Side Marker and Clearance Light with Two Amber LEDs and a Recessed Grommet Mount. .

I bought 6 of these lights to put on my jet ski trailer. 4 amber and 2 red. And they are very bright. I highly suggest putting these lights onto your fenders. I put an amber and a red one on each fender in their appropriate locations of course. It helps when backing up into small dimly lit spaces at night...like a driveway The red ones reflect off of whatever you are backing towards...and the amber ones give you an idea how close you are to walls or trees in the side mirrors. Just be cautious when you put them in. Make sure that in your mind everything is good to go (like, say, the wiring), and you do not need to pull it back out. If you push it in all the way...good luck getting it out. The grommet mushrooms out at the bottom basically locking it in place. If there was a warning about this on this site and I missed it...my bad. I just made sure I left them all loose until I was done, made sure the wires in the trailer (especially the ground wire) were not getting stretched or pinched, as my trailer is old, and then pressed them all in by hand. I made the mistake of pressing one into my passenger fender...just to see how it looked. This was before I started wiring anything. At this point I was drilling the 3/4" holes...which by the way is very time consuming. I spent a few minutes trying to remove it without damaging the wires. No luck. Not even a little did it want to budge. And I was able to get at it from the top and bottom. Thank goodness this didn't happen with the holes I put into the sides of the trailer because I think I may have had to destroy that light just to get it out and wire it up, which would have sucked because I think that would have pissed me off to the point of not even wanting to use the lights anymore and I would have picked something else out. And that would have been a shame because these lights put out an incredible amount of light. When you put them in the first time, they give off a sort of weird glow. I thought my eyes were playing tricks on me at first. If you manually adjust the lights to the proper DOT code or whatever, they look good. But, if you rotate them so that they are horizontal instead of vertical, they put out a ton of light towards the street. What I'm saying is...if you want to change it up, you can turn them all horizontal in a matter of seconds, and be lighting up the road...literally...just like the neon vehicle underbody kits of the 90's. Admit it. You thought they were cool too. Now, you can sort of have that, except it's legal. I went overkill on my small trailer. At least I thought I did. Now, after using it at night, I am more than satisfied. What a huge difference these tiny lights make. A++++SELLER. WOULD BUY AGAIN. ASSET TO ETRAILER.COM 147443

Just installed recently, Lights mount nicely in a 3/4" hole. Wiring harness about 8 inches. Just as bright or brighter than standard size clearance light. They work and look great. I used them on the front of fender step mounted on a 45 angle . Not sure if they meet "reflector" requirements for corner light but works great as indicator to on-coming traffic (and width marker when looking in mirror) and side marker light. As far as reliability or longevity, don't know, but they appear to be well constructed and sealed lights. 94576


So far theyve still been working well, they are very bright and while towing at night, they light up the yellow line on the highway nicely so I know exactly where my fender is and oncoming traffic can see. I added some yellow reflector tape next to the light so that it meets reflectivity requirements, but as a light, its much smaller, looks cleaner, and less prone to damage than a regular clearnace light

These small lights were just the thing for marker lights on my boat trailer. Been under about 30 times and everyone is still working real strong, super bright for their seze

Buy these. The amount of light they put out for each milliamp they consume is impressive. The polycarbonate lens has a very defined left-right pattern. Get one and experiment with it to see how well it broadcasts bright light around to its sides. After installing these on my boat trailer, I was impressed with how much light these put out at 80 and 90 degrees to their installed point of focus. Drill a 3/4" hole and touch it out a few thousands to get an easy but secure installation. The 8" leads are good enough for most installations. These, and the red LED clearance LEDs, are a good deal. 13069

They are low profile in the day, and very functional in the night with their brightness. I did not expect them to be this good. I wired them as marker lights for my rear fenders. 149291

Found etrailer.com during a Google search for small amber marker lights. My order was small but did not matter to etrailer.com Got emails about my order status from placing to shipping! Received my order in record time and securely packaged and exactly what I ordered. Going to bookmark this page because they sell more items than what I purchased ! 158905


by: Keith08/07/2014

I bought these to use as blinkers for my off-road Motorcycle. They look really durable and will stand up to getting pounded off road but only time will tell how they do. They are really bright and easy to install. My only complaint was it was unclear if this was only for 1 light or a pair of two. The price is per light. 144866

by: Eric W.09/01/2014

I'm switching the lighting on my lawn equipment trailer to LED. These were an easy choice as they are bright enough to be seen and pass safety inspection but are small enough not to get knocked off or broken when loading and unloading equipment. 149449


by: James L02/27/2015

They look to be a quality product. I would have liked the bearings and races packaged so they could be stored with out damage or a chance of rusting. Two of these sets are spares so I don't have to sideline a trailer for an extended period. 176437


by: Dave E01/04/2011

Small clearance lights These little lights work nice, they take up so little room and are a snap to install. And the order process was great with Etraliers, they keep you informed through the whole process until they arrive at your door. 4994

by: Travis02/13/2013

Lights were very easy to install but the hole that you need is a little bigger than per the instructions. I used these lights to make a light kit for my polaris RZR. I am very happy with them. 66107


They are still working great

I plan to use these to replace the bulbs in my markers lights on the 1957 Corvette Trailer I am rebuilding. That way I can turn on the markers at night and not chew up battery! Thank You Bob 102618


by: Grant11/25/2013

I was surprised at how bright this little LED is! Installation was easy too. Just drill a 3/4" hole, push and pull it into place, connect the wires, then stand back and admire your work. 108481

Badass product, I just wish they made them to fit a 1/2" hole, could find a lot mor places to mount them. They're bright and awesome, but a little hat to place 68107


by: Dan F.06/23/2014

Very nice. Epoxy potting material extends further up the wires than I would have liked, but was able to trim it back without damaging wires. 137053
