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.

This is Optronics sealed, mini rectangular LED trailer clearance light, part number AL91RB. The lens is sealed and waterproofed against the housing of this light. Inside are three LEDs that draw a total of 0.051 amps at 12.8 volts. It is designed to snap into a mounting bracket that will connect our ground connection. Then you would use a single pole wire lead to connect to your running light circuit on your trailer. Now we are going to hook up the light to a power supply and show you how it looks. 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, mini rectangular LED trailer clearance light, part number AL91RB.

I cant tell you how disappointed I am...........that I did not find out about etrailer.com until now. The LED marker lights that I installed on my Haulmark Lowhauler are simply amazing. They are brighter than the big name companies truck lites out there that I had bought. It is too late for me to return my other lites but I went ahead and changed all the lights on my Nautique boat trailer with your products. It is the difference between night and day. Thanks for the great products. You have gained a NEW LOYAL customer. Speaking of that... I placed another order today. Thanks again!! 73758

I needed a replacement LED Tribar module and discovered etrailer.com. Great website, quick service. 220277


Comments

On three separate occasions, the modules have become disconnected and fallen off the tribar. Initially, I thought it was a fluke. After the third time I replaced the entire tribar with a metal one with permanently affixed modules. Additionally, the plastic around the mounting screw broke off leaving the tribar dangling.

Comments

Thanks for your review Charles. We do not currently sell the entire light assembly you have requested. But if you check out the items listed as related items on this page you could purchase the components to make a complete light assembly.

Great, brand name products and some hard to find LED side marker lights. Refurbished an old EZ Loader boat trailer for carrying kayaks. Old incandescent lights were rotted off of the frame and the side marker lights in the fiberglass fenders were inside rubber grommets that were dry rotted. Etrailer had all the replacement lights, available in LED, and beat the price of any other option. Quality products. Delivered in 2 days under a free shipping promo. Etrailer is saved to my favorites for any trailer needs. Pic of the Yak project attached. New tail, fender and side marker LEDs! 408451

Working on 1982 tandem axle boat trailer replacing all lights to led. etrailer is the only one I found online that gave the dimensions of their lights & as a plus videos of them. Super store they are on top of everything makes all other competitors look stupid . Thanks for everything because of your attention to detail all the lights & light grommets were a direct fit saving me lots of time not having to retro fit anything. ANCHOR'S UP !!! 567766

Beautiful new LED lights. Nice and bright. I replaced all four (two red, two yellow) marker lights on my EZ Loader boat trailer. They give the trailer a brighter appearance than the older dimmer incandescent bulbs. One had burned out so I replaced them all for similar appearance. I'm sure the others were nearly ready to die anyway. Purchasing from etrailer was a great resource to locate, review, and purchase the products I needed - lights, trailer dolly, trailer jack - shipping was fast (and free with my order). Order follow-up and customer service is excellent. Highly recommend checking etrailer first before purchasing your trailer parts and accessories anywhere else. Excellent pricing, free and fast shipping - tough to beat that. 547433

Do you have a question about this Trailer Light?


  • Bearing Kit for 3,500 lb Trailer Axle and LED Clearance Light for Pace Utility Trailer
  • The thickness is right at 1/8 of an inch for the mounting plate of the spare carrier part # FSTC1000301. For the LED version of the light in your picture you would want the part # AL91RB. Or part # MCL95RB for a version of the light that includes a base. The correct bearing kit for a 3,500 lb trailer axle is the part # BK2-100.

  • Recommended Side Marker Lights for EZLoader Trailer
  • I can help you find the correct parts for your EZ Loader trailer. Based on the photos you submitted, the # AL91RB will fit your style connector on your trailer. The amber light is # AL82AB, and the grommet you will need is # A91BOB. All these items come in quantity of 1 so you will want to adjust the quantity on the grommets page to 2. I have linked all the above products to this page for your convenience.

  • Parts Needed to Install Optronics Submersible Red LED Clearance and Side Marker Light AL91RB
  • The Optronics Thinline Submersible Red LED Clearance and Side Marker Light # AL91RB installs using a base, part # A91BOB in black or part # A91OB in chrome finish. A 2-wire pigtail # A46PB will allow for electrical installation. The white wire on the pigtail is ground. If your original light used only 1 wire then its base provided the ground connection. In this case you can use the self-grounding base # A91BB in black or # A91CB in chrome finish. In this case you will use Single Wire...

  • LED Trailer Lights for a Lark Trailer
  • Sounds like you have a T17 Torx bit that you are in need of. Your local hardware store will have this size. Try a Lowe's or a Home Depot. It is possible that you could replace your trailer light bulbs with LED bulbs, but most likely you don't have the correct housings that allow for that as most do not. I attached a page that has all of the LED trailer taillights we offer.

  • Recommended Amber, Red, And Clear Lens LED Clearance Lights For Karavan Boat Trailer

These are LED lights and are submersible. These measure 2-1/2 inches long and 1-3/16 inches wide and 7/8 inch deep. For a red clearance light I recommend part # AL91RB. The clearance lights with a clear lens has amber colored diodes. We do not have a clear I recommend part # AL91CAB. All three of these lights have the...

  • LED Clearance Light Recommendation for Sundowner Horse Trailer
  • What you have on your horse trailer is a pretty common clearance light that we do offer in red and amber as an LED. For the red you'd want the part # AL91RB and for amber part # AL91AB. You'll also need the grommet part # A91GB and the right angle pigtail part # A46PB and you'd be set.

  • Will Optronics Side Marker Light # AL91RB Mount in Existing Rubber Grommets on Trailrite Trailer
  • The Optronics Clearance/Side Marker Light, part # AL91RB, will mount in the rubber grommets that your Grote 4641 lights are installed in. I looked it up in the industry cross reference for lighting and it listed the # AL91RB light as fitting in your grommets. The rubber grommet we offer for the # AL91RB light is the Optronics Flush Mount Grommet, part # A91GB. This is a rubber grommet that is used when mounting the light flush to the trailer. It measures 3-5/16 inches long x 1-15/16...

  • Should LED Trailer Lights be Mixed with Incandescent Trailer Lights
  • One main difference between LED lights and incandescents is the amount of power each one draws. I did a little research and found that if you were to have LEDs and incandescents on the same circuit, it would be too much power draw for the LEDs without using the proper resistors to compensate for the differences. It would be best to replace all the lights to one type or the other. However, if one of your stop/turn lights was LED and the other was not, that should be fine (provided both...

  • Looking for Boat Trailer Clearance Light to Replace Signal Stat 1500
  • According to my Optronics representative, the # AL91RB marker/clearance light you mentioned is a direct replacement for the Truck-Lite 15 series. The Signal Stat 1500 is how Truck-Lite refers to the same lamp in its LED version. A mounting bezel is available, part # A91BB for black or # A91CB for chrome plated ABS. If either one of these self-grounding bezels is used, use a # A91LW pigtail. If a non grounding bezel or bracket is used, a two wire pigtail like part # A46PB would be needed.

  • How to Wire up the Thinline LED Clearance and Side Marker Light to Single Wire Trailer
  • To use the # AL91RB on a trailer that has one wire for the power wire and then grounds through the mounting bracket would only require the bracket part # A91BB for the bracket and then part # A91LW for a single wire connector.

  • For your Trailer Tail Light - Stop, Tail, Turn - LED - Waterproof - 10 Diodes - Red Lens # STL72RB and Thinline LED Clearance and Side Marker Light - Submersible - 3 Diodes - Rectangle - Red # AL91RB, you will need the Wiring harness # A45PB as well as # A46PB. If you want the side marker light to only be a running light you will connect to the black wire. If you want it to be turn only, you will need to use the Vehicle to Vehicle Tail Light Converter # 118158 to isolate that function.

  • Hyperflashing On Trailer Lighting with a 2013 Ford Escape Troubleshooting
  • Typically hyperflashing is a problem with LED's being installed on a vehicle that had incandescent bulbs. That problem usually does not occur with trailer wiring. Unless in your case the tow package wiring has it's own flasher unit separate from the vehicle taillights. Which if it does then you would need to replace all of the taillights of the trailer with incandescent bulbs or install load resistors on all of the taillight circuits on the trailer.

This red clearance light measures 2-5/8 inches long, 1-1/4 inches wide and 3/4 inches in height. Another option is the Optronics Thinline LED Clearance and Side Marker Light # AL91RB.
