Optronics light dimensions

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 circuit board is sealed, which means that water will not damage the diodes or circuit board.


PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and a side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL11RKB Review

Today we are going to take a look at Optronics sealed uni-lite mini LED side marker, part number MCL11RKB. Both the lens and the housing are sealed and waterproofed. Inside are two red LEDs that consume 0.030 amps at 12 volts. Optronics covers these LEDs with a lifetime warranty. The light is a two wire system, meaning you will have two wires coming off of the back, white for ground and black for power. Next we are going to hook it up to a power supply so you can see how it looks. We will connect the white to ground and black to power. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics sealed uni-lite mini LED side marker, part number MCL11RKB.

Love these l.e.d. lights. Had seen exact same lights on a new truck at work and wanted them for my personal truck. Found them here on etrailer at a great price. They are really bright for such a small light and low current draw. Simple, fast install. 109134

Great addition to the basic, rear brake lights of a camp trailer. I added these LED RED to the brake/turn function, within the existing, small holes in the rear bumper--much more apparent when stopping/turning. These sealed LED lights are very common on larger trucks and trailers now. Easy to install and very robust assembly...priced right! 396057

Always great, tested products from ETrailer. These LED lights did not disappoint...still shining brightly. Thanks!

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 147445


Comments

What a great idea. Follow up with customers to get feedback. That way you can tell if the products are still good or if they have limited lifespans. You get to see if people are still happy and get them thinking about your company again if theyre in the market for more trailer stuff.To answer your question, I do not have them anymore. I sold all of my gear, but do know they are still working. I really liked those small lights. They put out an incredible amount of light and were easy to install once I drilled holes into my old trailer.

I bought a couple more of these two-diode LED clearance lights to add some more lighting to the rear of my kayak trailer. They work nice and are easy to install in 3/4" holes that I drilled through a piece of aluminum angle. The trailer has orange clearance lights on the front sides, red clearance lights on the back sides, the stop/turn/parking lights on the back, three red clearance lights on the back, and a white LED license plate light. It's really lit up and very visible at night from the rear and sides. Thanks to etrailer.com for great products and services! My wife and I like to kayak, but we don't like to deal with putting our kayaks on roof racks on the top of a car. So I bought a used Load-Rite trailer that was designed to hold one Jet Ski, and added a frame made of slotted angle and 2x6 lumber to hold the kayaks, and a cargo box from Tractor Supply to hold kayak seats, life jackets, towels, sun-protection clothing, and some spare gear (ropes etc), and bought all new LED lighting from etrailer.com. The paddles are too long for the cargo box so they have to go in the car! The kayaks are tied down to the trailer with several ropes front and rear, so there is a lot of safety factor in the design....I don't worry about the kayaks coming off the trailer! The entire rig works great....when we return from a kayak trip we just back the trailer in the barn and it's ready to go for our next trip. I put a 5" diameter wheel on the trailer just behind the hitch so I can push it around on flat level surfaces. See the pictures. 296904

Those lights, and all the lighting and trailer wiring products that I bought from etrailer.com, are working great! I used to have constant problems with the lights on my trailer until I switched everything out to the LED lights from etrailer.com! Now they work every time we use the trailer knock on wood!.

I ordered these light to be used as accent light on a new lift table for my company. I needed low profile and fairly bright red light to be reflected off our off-white power coat. These little lights out preformed what we were hoping for. The only thing I don't like about them is the instructions say to drill a 11.16" hole. Assembly was WAY too tight at that dimension. So we stepped it up a fraction at a time and found that 17/64" (.73) and 3/4" (.75) were perfect. Even at 3/4" the grommet was snug and water tight. The light had to be squeezed into place but at 11/16" I felt like I was about to brake the light. Overall I am super pleased with the lights. We added them to the Bill of Materials and we will be ordering them for these new carts. 620141

Needed small lights for parking lights for my RZR to make it street legal... They fit the lip of the fender nicely and are very bright. Would also work for turn signal lights as they are as bright as the surface mount ones that came in the kit i bought. Would have looked better too. These set back in the grommet much farther than in the picture, they look good. 496731

Comments

All the led trailer lights are still working great. I get lots of compliments on the halo oval LED tailbrake lamps. The only Improvement I would like to see, I think the Halo stoptail, should have a brighter Stopturn, then they have. in the daytime, if you are running the tail lights, there is not a BIG visible difference. Other than that, I am very happy with the purchase.

Great! Thought I had a problem with them, turns out it was rodents! I put the lights at the top of the trailer ramp on either side so I can see it better when towing in the dark.

I really like these little marker LED lights. They are nice and bright and by rotating the housing you can somewhat adjust the beam pattern. I've used the yellow lights on the front apron of my F150 as marker lights and the red ones have been installed on the rear of my truck as running lights and also turn signals. I especially like that they are epoxy-sealed units and the wires have a rubberized sleeve for exterior use. I really wish that these lights would come in a dual intensity version so that they could be used as both running lights-turn signals or running lights-brake lights. 438384
