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.

Another great experience with etrailer.

Fit great with the gasket that goes with it. Great company to work with. Thanks Etrailer.



by:

Thanhs Dave for taking prompt care of my order.



by:

These Thinline led lights replaced my incandescent ones perfectly as id lights for my boat trailerl. etrailer has great pricing and the item was in stock. These are brighter than oem and should outlive the original lights. This decision was made easily to upgrade to these. Friends of mine as well as myself have made purchases from etrailer before and have been very satisfied with our purchase. Customer service is good. No reason to look anywhere else.



by:

Works as advertised.



by:

Timely delivery. Plug and play fitment like original. Just what I needed. Working great after one year of use.



by:

Perfect match to original incandescent and mates with existing wiring.



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!



by:

Products were as described and prompt shipping too.



by:

Illuminating experience!



by:

Just what I needed. Good value and we received it in a timely manner.

The LED lights are so much brighter and reliable. I highly recommend.

  • Are Mounting Brackets Needed To Install Optronics LED Trailer Clearance Lights # AL91RB
    For installation of the Optronics LED Trailer Clearance Lights, part # AL91RB, you will need to use an Optronics Mounting Bracket. You can use either the Optronics Black Mounting Bracket, part # A91BB, or the Chrome Mounting Bracket, part # A91CB. The brackets are sold individually, so you will just need to order the same quantity as the number of lights you have. I have linked a video that show the installation of the Optronics AL91 Series Lights.

  • Can LED and Incandescent Lights be Mixed, Used at the Same Time on a Trailer
    The lights don't have voltage or amperage regulators so it could potentially be an issue. However, I am in the minority around here about whether or not it would be a problem. Most others are certain that it would not be a problem so majority rules. I still believe that the potential for a problem is there if you mix LED and incandescent lights but it seems to work out for most people. But I would be remiss in my duties if I didn't at least mention the potential for a problem.

  • 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.

  • Optronics Trailer Clearance Light Similar to AL 91RB that Installs With Smaller Hole Drilled
    The Optronics clearance light part # AL91RB in all of it's configurations would require a hole to be drilled for a harness like the part # A46PB to install with a grommet like the part # A91BOB. There isn't a way to mount it flush without drilling. If you used the part # AL82RB instead though it would require a much smaller hole be drilled since the entire harness of the other setup gets ran through the hole.

  • 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"...

  • Replacement Rear Clearance Lights For a Sure-Trac Utility Trailer ST7211HST-B-030
    Based on images I could find for your Sure-Trac utility trailer model ST7211HST-B-030 it appears is uses either the Incandescent # A91RB or LED # AL91RB lights. These are held in place with the Grommet # A91GB which is 3-5/16" long x 1-15/16" wide. If you have a different style or size light please send me some images with measurements and I can verify what we have for a replacement.

  • Mounting Bracket Recommendations For Optronics Thinline LED Clearance and Side Marker Light
    For the # AL91RB trailer lights we have a couple options for mounting brackets. For a self-grounding bracket where the light is grounded through the mounting hardware I recommend part # A91BB. The gasket is included. For a mounting bracket that has an open back you need part # A91BOB.

  • Recommended Amber, Red, And Clear Lens LED Clearance Lights For Karavan Boat Trailer
    The clearance lights we offer are not exactly the size you mentioned but these may work well for your trailer. I recommend part # AL82AB for the amber lights. 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 same measurement...

  • Troubleshooting LED Identification Light Bar With Lenses Easily Knocked Off
    The LED Identification Light Bar for Trailers over 80" Wide - Submersible - 9 Diodes - Red Lens # MCL93RB has the wiring and housing for the individual sealed lights # AL91RB to fit. The only way to help them stay in place a little better is to add silicone around the edges to just add an additional seal that will hold up to vibration and water. An alternative option is to use the LED Identification Light for Trailers Over 80" Wide - 3 Diode - Sealed - Rectangular - Red # MCL98RB which...

  • 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...

  • How Does the Red Side Marker Trailer Light # AL91RB Install and what Parts are Needed to Install
    For the clearance light # AL91RB and the matching amber light you would install the lights in the appropriate bases like # A91BB and then use 2-wire pigtail # A46PB, plug it into the backs of the lights and attach the wires to the existing trailer wiring. The ground wire can be attached directly to the trailer frame. I have included a link to a video review of the clearance light for you.

  • Red Optronics Clearance Light Needed and Matching Chrome Mounting Bracket
    The Red version of the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light # AL91CAB from Optronics is found as part # AL91RB on our site. The Chrome mounting bracket for both lights is part # A91CB and works with 90 Series or 91 Series Optronics lights.

  • Troubleshooting LED Single Wire Clearance Lights
    The reason your single wire LEDs aren't working is because you aren't using a ground. Most single wire lights like the Amber Clearance Light with Stainless Steel Hardware # 47-99-006 will have a separate ground like in the mounting hardware. The Thinline LED Clearance and Side Marker Light # AL91RB you asked from will ground through the mounting bracket # A91BB. The mounting with butyl tape is the issue. You need to have a ground connection for your clearance lights to work.

  • Looking for LED Version of # AL91RB Mini Rectangular Clearance/Side Marker Lamp
    You bet we do! For the LED version, you'll need part # AL91RB. The lamp can be grommet mounted using # A91GB or surface mounted using a self grounding base like # A91BB for black/ # A91CB for chrome or a standard base like part # A91BOB for black/ # A91OB for chrome. If you use a self grounding base, use the single wire pigtail, part # A91LW or for the standard base, use the two wire pigtail, part # A49PB.

  • Size of Mounting Hole Required for Installing Optronics Grommet # A91GB
    The Optronics Grommet # A91GB that you referenced, which is designed to work with the Thinline LED # AL91RB that you were looking at, will install into a mounting hole on the trailer that is 2-7/8 inches across and 1-1/2 inches tall. If you do not have this type of mounting hole on your trailer, you can use the Mounting Bracket # A91BOB instead, which will allow for a surface mount installation. I have attached a couple short video demonstrations on these products that you can also check out.

  • Replacement Fender Solution for 2005 Crestline Trailer
    I looked up the Shorelandr fender SK0329-01 and our closest option is the Fulton fender part # F008574 which measures 9-5/8" Wide x 42-5/8" long x 12-3/4" tall. To add clearance lights to this you'd need the part # AL91AB for amber lights, part # AL91RB for red, part # A46PB for pig tails, and for grommets # A91GB.

    The closest Optronics trailer light assembly we have available to your existing unit is the Optronics Thinline LED # AL91RB. This LED light measures 2-1/2 inches long and 1-3/16 inches wide. The mounting bracket # A91BOB it is used with (not included with the light) features bolt holes that measure 2 inches apart on center. Unfortunately the SAE P2 P3 number you found on the lens of your existing light doesn't indicate the actual light model but has to do with DOT regulations. If the...

  • How to Wire up the Thinline LED Clearance and Side Marker Light to Single Wire 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.
