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 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.

SPLENDID! Popped the old incandescent Side Marker Lights out on my 2008 Triton 21X2 trailer and installed these Thinline LED Clearance and Side Marker Lights (both the AMBER and RED ones). Just Plug-N-Play and my boat trailer looks AWESOME! Shipping was a snap!



by:

Very bright light, same connectors as my 2001 Shoreland'r boat trailer, just had to plug them in.
Cannot say enough about the staff at etrailer, very helpful.



by:

I have been more than pleased with the Optronics brand lights! These are no exception!

I, like others, am amazed at the brightness of the lights. They are a huge upgrade over my existing incandescent lamps!

I really like the way them mate with the mounting brackets and wire connectors. They snap into the brackets securely and can be removed. I also like the matching connectors as they also snap into place securely.

I would buy again and I would recommend to others as well!

A year later and Ive had zero issues with the LED lights. All the individual LEDs continue to work and the brightness has not diminished over time! Im extremely happy with these!



by:

Perfect fit and really like the led providing some extra lighting around the trailer.



by:

Boat Trailer: Following a highly successful conversion of the brake/tail & DOT lights, I went ahead with changing the amber running/side maker lights. Working with Hally made ordering smooth and simple. The parts arrived via USPS as expected in excellent condition.
The new LEDs fit perfectly into the OEM housing, so I chose not to change them at this time. THe difference in illumination is just outstanding!!!
I will definitely use eTrailer again with two great experiences on this project.
Seeing the outcome, I cannot explain why it took me so long to decide to convert.

After a year and around 2500 miles, the lights continue to perform flawlessly. It was a good decision to convert to LEDs and I will not wait as long should there be a next time.



by:

Top notch!!! Worked great on my boat trailer. Great product!!!



by:

Lights worked fine. I sold the horse trailer once the lights were fixed and the new owner is happy with it as far as I know.



by:

Haven't used trailer yet to see if they even work but ,they seem perfect snapped right into place,exact replacement



by:

I needed to replace this light on my boat trailer. This is the exact replacement and it fit perfectly. I also installed a new rubber grommet at the same time. I am glad Etrailer has what I need to keep my light's working at a reasonable cost.



by:

I didn't realize these don't come with wires. They are for mounting on posts. I had to solder wires onto them.



by:

More lights on a trailer is never a bad thing. These were easy to install and wire up.



by:

Easy to install and looks to be a exact replacement for the factory installed running lights on my boat trailer.

Great



by:

Much brighter light from all viewing angles than the OEM lights. Easy snap in replacement if it ever fails. The self grounding one-wire base would have made my install easier. The two prong plug I ordered was a tight fit but it worked.

I would recommend etrailer.



by:

All the lights fit and worked great. I had one taillight that was broken when it was delivered, but I emailed them, and within an hour, they had a new one on the way to replace it at no charge. This is why I keep coming back because of the excellent customer service!



by:

It looks really nice now with the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light.



by:

Perfect replacement



by:

Very good material works perfectly



by:

LED lights are great. The Fenders were just as I needed to replace on a Triton bass boat trailer. Only thing wrong was one had a small dent. Got it bumped out and ready to paint. Good overall satisfaction with the products.

Doesn’t come with everything needed to make it work?

This light is meant to be just the replacement light. It can be mounted a few different ways such as with a grommet like part # A91GB or a mounting bracket like part # A91BB. The 2 prong plug is part # A46PB.



by:

Overall, the product met my expectations. As for Etrailer's customer service, I was sent an email saying that my order was shipped by George when he shipped my order. I received what I had ordered, and it arrived on schedule.



by:

Still working after a year.



by:

Exact replacement. Easy install. Great service

I'm very pleased with these LED replacement lights for the fenders on my cargo trailer.
Before these I had the regular light bulb which I had to replace from time to time. So the last time I needed to replace a bulb about a year ago I decided to go with these LEDs.
Wow what a difference in their brightness.
Before changing to LEDs my lights on the fenders were somewhat dim. Now with the LEDs these lights are bright enough for other divers to see them in the daylight giving me some peace of mind that they see me coming.
There is however one con to them being so bright.
When I have to back my trailer into the driveway at night their brightness blinds me from seeing my wife in back of the trailer guiding me in when using my review mirrors.
But it's OK because now I will just get some LED backup lights for the trailer.
I plan on changing the entire trailer over to LED lights, someday. lol
PS. I love etrailer.com

Its been a year of having these lights on my cargo trailer and Im still loving them. Nice and bright to warn other drivers either in front of me or in back of me the width of my trailer coming down the road. I run them day and night and 99 of all drivers coming head on at me I see they pull over just a little to widen the gap between us as we pass each other. I have a cargo trailer with fenders mounter outside the trailer with a little black plastic rubbery housing that holds the lights. I put the amber light facing forward and the red light facing backwards. Just take the black housing off the fender then pull out the old and install then new. Was a good time to clean up the ground wire connection while I was there too. Took 10 minutes or so per side. Theyre awesome. Getchya some here at etrailer.

  • Replacement Clearance Lights For a 2017 Skeeter Boat Trailer
    Looking at images for a 2017 Skeeter boat trailer it appears they use the Mini Clearance/Side Marker Light # TN96MR on the rear of the trailer to fit into a 3/4" hole. And the Thinline LED Clearance and Side Marker Light # AL91AB just in front of the axles. This is a recessed style light that is 2-1/2" long x 1-3/16" wide. It is designed to fit in a Grommet # B150-181 or on a Mounting Bracket # 150-13. We also have Angled Grommet # A91GZB as this is what your trailer appears to use.

  • Does The Optronics LED Side Marker Light # AL91AB have 2 Male Connector Posts
    Yes, The Thinline LED Clearance and Side Marker Light # AL91AB has 2 male connector posts on it. This waterproof trailer light functions as both a clearance light and a side marker light when properly mounted. It is 2-1/2 inches long by 1-3/16 inches wide by 7/8 inches deep. The Right Angle 2-wire pigtail # A46PB and The Mounting Bracket # A91BOB are sold separately. I attached a review video link below.

  • Recommended Replacement Amber Marker Light With LEDs for a Boat Trailer
    Jim, so size wise and LED wise the Thinline LED Clearance and Side Marker Light # AL91AB is the closest we carry to what you need. This light measures 2 1/2" long, 1 3/16" wide, and 7/8" deep so it'll be about 5/16" less wide than your current light, but could still absolutely work. Pictures would definitely help understand what you're describing, so if you could send some in that'd be a big help.

    Yes. The only difference between the Fulton # F008584-2 and the Fulton # F008594-2 is the color. Both of these step fenders are designed for 14" wheels. If you need mounting brackets you can use the Mounting Brackets for Trailer Fender - 13"/14"/15" Wheels - Galvanized Steel - Qty 2 # CE26098G-2 and you can add clearance lights on these fenders with the Thinline LED Clearance and Side Marker Light - Submersible - 3 Diodes - Rectangle - Amber # AL91AB (LED) or # A91AB (incandescent).

  • Replacement LED Trailer Lights For a 2003 Pace American JT612TA2 Enclosed Trailer
    Unfortunately Steve, I have no way to see exactly what lights came on your 2003 Pace American JT612TA2. Based on some images I could find it looks like your trailer uses the oval style light like the Optronics # STL72RB which is 6-7/16" long. If yours is a different length please let me know. For the clearance lights on the fenders they look like the snap in lights like the Amber # AL91AB and Red # AL91RB. The top 3 marker lights look like the # MCL0032RBB. These are the very common 4"x2"...

The # AL91AB lights will snap into the # A91BOB and then the # A46PB will plug directly into the back.

  • Are Red & Amber Square Trailer Clearance and Side Marker Light Submersible
    Hello Michael, The Square Trailer Clearance and Side Marker Light with Reflex Reflector - Amber # MC37AB and Red # MC36RB are only available in non-submersible versions. There isn't a light with the exact same 2-3/4" L x 2-1/8" W dimensions that is submersible but we do have options that are submersible like the 2-1/2" x 1-3/16" Thinline LED Clearance and Side Marker Light - Amber # AL91AB and Red # AL91RB.

  • Replacement Fender for Single Axle Escort Boat Trailer
    The only white fenders we have that will fit your 15" wheels are the # PF11X35W-2. We also have reports that this was a match for a 2000 Escort boat trailer, so it is likely this is the same part. If you decide you only want to place the one fender we do have a single fender available as well # PF11X35W. We don't have the same mounting bracket style so you would need the # PF1135-BKT-2. The mounting holes on the brackets are 3-5/8" apart so you would need to acquire U-bolts from your local...

To mount this light you have a couple options. The first is the Mounting Bracket # A91BOB with Right Angle 2-Wire Pigtail # A46PB; you'd also want to use the Self-Tapping Screw # 1131832.

  • Replacement Tail and Marker Lights for 1996 Ranger Trail Boat Trailer
    Excellent idea, switching to LED. They use less power, last much longer and are brighter than incandescent lamps of the same size. Win, win, win. The grommet mount lamps you reference should fit in a 6-3/4 by 2-1/2 inch rough opening, which is the typical size. I'd recommend measuring the rough opening to confirm. If that dimension checks out, the # TLL12RK LED taillight kit would work well for you. For the marker lights, if the interior of their mounting brackets measure 2-1/2 by 1-3/16...

    You can convert your RV to separate turn signals and/or LED operation in a couple of ways, depending on how much wiring modification you care to do. Any of your existing lights can be converted to LED operation by swapping out the incandescent bulbs for LED-type replacement elements. We have LED equivalents that are drop-in replacements for many popular standard bulbs. All appear on the linked page and can be selected by bulb number, such as the popular 194 type bulb # A194B that can be...

  • Should I Change My 5 On 5.5 Wheel Bolt Pattern To Something More Common?
    With the options being as limited as they are for the 5 on 5-1/2 bolt pattern, I do recommend changing to something more common, specifically the 5 on 4-1/2 bolt pattern. This is very widely available and it will not only give you more options for wheel design, it will also be significantly easier to replace if ever needed. The only drawback to doing this is that you will indeed need to replace your hubs to get the new wheels attached. The vast majority of hubs that used the 5 on 5-1/2...

  • Troubleshooting Trailer Wiring Blowing Fuses
    While we have no specifics on wiring for any make or model of trailer and can only generalize it does sound like something very simple - you have overloaded your running light circuits which is causing the fuse to blow, and the reason for that is almost always because you are using incandescent lights as opposed to LED lights. If this is the case, which I'm guessing it is because it is the most common, you will need to switch out at least your running lights to LEDs, and can do so cost-effectively...
