Optronics MCL13 Series LED Clearance Marker 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.

I initially purchased a marker light to replace one that failed on my boat trailer. I liked it so much I bought enough to replace all the side markers. They are bright and because they are LEDs, there are no bulbs to burn out. Highly recommended.

- MCL13A2B

I have purchased 8 of these and they always fail due to water intrusion through the wires. While the light itself is water proof? the wires are NOT. So, if you want waterproof trailer lights you have to find a way to keep water out of the stranded wires that go to the light. I have used self sealing connectors without success and have used special heat shrink with sealing glue that melts all around the joints without success. If the wires were solid copper and shielded perhaps they would work!

- MCL13A2B

they work great will buy all of my trailer light from your company

- MCL13A2B

We use these lights here at Treeline Helicopters as indicator lights on our aerial tree saws, they are exactly as pictured and great quality, we’ve also used several heavy trailer products from etrailer and are very happy with the fast shipping and customer service!

- MCL13A2B

Product arrived quickly and was easy to install as a replacement side marker light on a boat trailer I was restoring.

- MCL13A2B

The light works great, and really makes my trailer more visible at night. Shipping was very fast and order was perfect.

- MCL13A2B

The light looks good on my trailer I built to pull behind my motorcycle. I have used all led lights on the trailer for less draw on the bike. They are nice and bright in the day and night.

After a year the lights are still working great. I have had a few people ask me where I got the lights and I let them know etrailer has them for a good price.

Awesome front marker light. I have a 16ft inflatable boat that I take on the ocean several times a month during the summer. The boat sits low and I need to back the trailer deep for each launch. These front marker lights are always partially submerged every time. They are completely sealed and work perfectly. The lead wires are fairly long, but the connection to the boat trailer wiring is underwater on each launch. I just spent a little time covering each connection with Marine Sealant 4200 from 3M. My lighting is now completely waterproof.

- MCL13A2B

Low profile and rugged. Bright LED.

- MCL13A2B

Great selection, quality products, super service. The light was just what I needed. Would definitely use etrailer.com again and recommend to others.

- MCL13A2B

I am renovating an old boat and trailer and the clearance lights and tail lights were no good. I found these clearance lights on etrailer that are perfect for replacing the old lights. These lights are made for easy installation and are water proof LED. I searched many on line stores before deciding on these and price was not my only consideration. And they arrived super quick which I was not expecting. I recommend these lights.

- MCL13A2B

Excellent customer service, fast deliver, items worked as described. This is why we shop only here for all towing and trailer needs. Thanks

- MCL13A2B

They were delivered fast.They are just as was described. Should last longer than previous lights because they're sealed wires

- MCL13A2B

Patrick: I just received in the mail the A-Frame coupler CA5100B, and two Mini LED Side Markers MCL13A2B. I haven't yet installed them, but all appear of very good quality, especially for the price. We're using these items only for a small utility trailer we bought at a yard sale, so we didn't need anyhting much sturdier than what we bought. The mailing service was very prompt, and was I was kept well aware of my order status. If the need arises, we'll be sure to do business with you again. Dominick

Nice quality lights thanks

- MCL13A2B

Works great, put a few extra on my trailer provides lots of light.

- MCL13A2B

Lights came in last nite. I have a wells cargo double axle 6x12 trailer that I'm going to "spiff"up.im adding and replacing old marker lites and these mini LED lites with chrome trim were the answer! I will send you pics of before and after when they're mounted. Great looking lites and good price .

- MCL13A2B

My order arrived in a timely manner and was packed very well. The marker is just the right brightness and after all the bad weather it still looks the same and functions very well. The pricing was the best I could find also. Thank you ettrailer

- MCL13A2B

So far so good.I like them and would buy them again

- MCL13A2B

The corner marker lights on my trailer take a lot of abuse from gravel roads these optronics lights are much more durable and brighter than the lights that came on my trailer. Thanks etrailer!

- MCL13A2B

Excellent products and excellent service. I never have to wait to receive parts from the fine people at etrailer and the quality is always excellent. My latest purchase, two pair of side marker LEDs installed easily and work perfectly. Thanks etrailer!

Thanks for asking. I havent had any problems with any of the products Ivereceived from eTrailer, ever. I have several trailers, all of them have someof your products on them and while I do check their operability before I geton the road with them, it is more about safety routine than concern thatIll have a problem.I think eTrailer is one of the best online stores period, I value yourbusiness and appreciate all of the excellent customer service you provide. Ispread the good word about eTrailer whenever I can. I appreciate yourfollow-up. It only reinforces my opinion that you all are tops in customerservice.Best Regards

I’ve used this for about 9 months on an off-road adventure trailer, and it’s held up great. I like the design, they’re easy to install and the plastic lenses snap in snugly. I also like that they’re low profile and don’t stick out much at all. Great product.

- MCL13A2B

Can't go wrong with LED... no more bulbs to smack when they don't work and forget to replace them afterwards Cheaper than a ticket for defective equipment!

- MCL13A2B

These lights are great. Easy to put on and the backup lights are bright enough to see in the dark .

- MCL13A2B

The lights were exactly what I needed for my trailer.
