Swapping old bulbs for reliable LEDs makes a big difference in how your trailer stands out. This 2-1/2" diameter red beehive light uses 8 LEDs that last up to 50 times longer than standard incandescent bulbs. With only 0.061 amps drawn at 12.8V, it’s both bright and efficient, giving off clean light while keeping the power demand low. No bulbs to replace, no fragile filaments—just consistent performance every time you hook up.
If your trailer sees heavy rain or even full submersion, this light is built for it. The housing and lens are sonically sealed into one solid piece, making it completely waterproof and submersible. That means no water creeping in to fry the diodes or corrode the wiring. Even after repeated dunking, you can count on the light to stay sealed and dependable.
Road grime, gravel spray, and vibration can take a toll on lesser lights. This one is made with a durable polycarbonate housing and lens that can handle the abuse of regular towing and still look good doing it. It’s designed to stay secure whether you mount it flush or recessed using the proper grommet (sold separately), keeping your setup tight and clean.
Visibility is key for safety, and this P2-rated light throws its beam 45 degrees to each side of centerline for a total of 90 degrees of coverage. That focused spread makes it ideal as either a clearance light or a side marker light when properly mounted. You’ll have confidence knowing other drivers can clearly see your trailer’s edges at night or in low-light conditions.
No complicated wiring here—this light accepts any industry-standard 2-prong plug such as the A46PB or A86PB (sold separately). It mounts with an optional grommet to keep things neat and secure. The setup is simple: connect power and ground using the plug, press it into the mount, and you’re ready to roll with bright, efficient LED lighting that just works.

Today we are going to take a look at Optronics sealed beehive LED trailer clearance and side marker light, part number MCL23RB. The lens of this light is sealed and waterproofed against the housing. Inside are eight LEDs that draw a total of 0.051 amps at 12.8 volts. It is designed to mount to your trailer using a 2-1/2 inch mounting grommet. And you will also need a two-wire plug to connect to the connection points at the back. Next we are going to hook the light up to a power supply so you can see how it looks. We will connect one of the contacts to our ground and the other to our 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 beehive LED trailer clearance and side marker light, part number MCL23RB.

Perfect fit a is better than the origin al.
Good service, great products, good product life! Very pleased with everything I bought from you. Best prices too!
Purchased product as described with fair price and quick shipping
Staff like these new lights because they are easier to see trailer at night when backing up.
Good looking marker lights for my Cardinal travel trailer. With the 2" grommet this will look wonderful.
Good product at a good price. Replaced my regular lights with LED lights from etrailer.com. Much brighter with less power draw. happy with purchase.
These really look great!
CAUTION: Nowhere in the description does it indicate that these come with NO WAY of mounting them. If you don't have an existing mounting bracket and pigtail (as was my case) they arrive and then you realize you can't get your project done because you lack parts.
Get the parts you need, and these are great!
Repeat customer here and always satisfied with product quality, prices and fast shipping. The side marker lights I ordered were exact fit for my snowmobile trailer. Thanks again!
these are NOT bright at all you cannot see the light is on unless you're coming at it from the full front on Ie. Facing it. the Leds don't light up the full amber lens. waste of my money
Just what we ordered thank you
While stripping paint from my 1948 trailer the stripping product damaged the running lights on the trailer. The new light quickly arrived from etrailer and were easily adapted to my vintage trailer. Here's a picture of the trailer with the new lights toward the front. Thanks!
They were the exact replacement (I had to reorder to get the correct size, my fault).
Had flush mount clearance lights on back of my trailer and couldn’t see where the back of trailer was at night, put these on and no problem seeing where the end of the trailer is now. They fit as they should and brightness is perfect.
