Parts were the exact match for the fender marker light on my Escort boat trailer. Previous owner had torn the light off and I could not find the parts locally. Etrailer had the
parts I needed.



by:

excellent trailer maintenance parts for the modular lights on my snowmobile trailer to replace very old rubber parts. Perfect fit. No issues a year later.



by:

good evening e trailersI really appreciated doing business with you I have looked all over New Orleans for those garments and no one had them I even work for a construction company and we have the pop in brake lights and everything else that goes with the garbage but everywhere I went in New Orleans the garments could not be found I either 121 auto parts store has been here for centuries and they have the lights but they didn't have the garment and they told me they don't make a garment that small and I had to prove that meant to that man that he was wrong so I have got them I have them in my hand right now I have 3 extra ones and I really appreciate it the next thing that I am looking to deal with you with is I am looking to replace my springs on my boat trailer and they 25 and a half from the center bote center note I am trying to find a kit with everything in it for my springs instead of just buying it Springs and then by the boats I'm looking to buy everything at one time so if you can help me if you have a kit for that size let me know email me back thank you very much



by:

Items were exactly what I was looking for. Perfect match, perfect fit. Delivered faster than expected. Will definitely use etrailer again.

After a year later Ive had no problems whatsoever with my trailer lights. Perfect replacement. Ive made other purchases from etrailer with the same great results.



by:

A little different than the lights on my 2002 EZLoader boat trailer. I think it is better than those that came as originals. I ordered enough to upgrade all of the running lights now and they are led and so nice and bright.



by:

I needed replacement clearance lights for my tow dolly after a blowout destroyed my old one. I wanted to up grade to led replacement and strainer was the only place I found a grommet mount led the size I needed. It fit perfectly with no adjustment and works great. Thanks etrailer for your extensive inventory. Ordering was easy and shipping was fast. These guys are the one I'll deal with in the future.



by:

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 !!!



by:

Folks, I decided to completely revitalize/upgrade my 20 year old bass boat trailer and found that not only could i find all the updated parts i needed, (led lights and urethane bow rollers, etc), at one location, additionally itrailer.com has a video for just about each part, where they share different measurements etc that may not be on the standard part description. These videos provided me with all the information i needed while configuring my retrofit. Additionally, when I placed my order, I received a personal email from the guy who packed my shipment., confirming that all the parts i ordered where in stock and now on the way. I typically never write these type of endorsements, but I felt compelled to write this one. Great service and all the parts I purchased have met my expectations. I'll be back when I need additional trailer parts.



by:

Perfect fit. Will order again when anything else is needed for my trailer.

Just like new



by:

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!



by:

Perfect fit. One worries that parts for an older trailer will not be available or will not fit. Very fast shipping - in fact, I got an email saying they could ship even faster with an almost identical part. I declined and it still came in a couple of days.

My new ranger trail fenders look better the the original. Appreciate the promptness and support finding what I needed.



by:

Products fit exactly as they should. Easy to install and replace. Shipping was very fast.



by:

Fit perfectly in our 2013 starcraft ez loader boat trailer



by:

I bought the whole set of LED lights - side and front side marker, tail lights, rear marker bar. It was quite a project getting them all in as they were of course slightly different than the 13-year old originals. But it turned out well and I was very pleased with the quality of all the components.

  • 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...

  • Grommet Recommendation for the Trailer Clearance and Side Marker Lights A91AB
    The Optronics Flush Mount Grommet for # AL91AB Series Trailer Clearance and Side Marker Lights # A91GB, will fit a hole that measures 2-7/8 inches across and 1-1/2 inches tall.

  • 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.

  • Replacement Clearance and Side Marker Lights for a 2019 EZ Loader Tandem-Axle Boat Trailer
    Hey Cory, welcome back and thanks for the picture. That's a tough situation you're in. I went through all of our submersible lights and I do not have a suitable replacement that does not require the use of the item # A46PB pigtail. My only solution is to use the Thinline LED Clearance and Side Marker Light - Submersible item # AL91RB in red and item # AL91AB in amber. They measure 2-1/2" L × 1-3/16" W × 7/8" D. These lights work with the following mounting brackets and grommets: Mounting...

  • 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.

  • Replacement Clearance Taillight Solution for EZ Loader 250-032130
    I looked up your EZ Loader part number and it appears to be the same design as the part # AL91AB which for the matching grommet you'd then need the part # A91GB. You'll also need the wiring harness # A46PB.

  • Replacement Trailer Clearance Light for PM150
    The most similar trailer clearance lights we offer to replace the PM150 lights you have now would be the Thinline LED light part # AL91RB. For a replacement harness that would plug into this you'd need the part # A46PB and then for a grmmet part # A91GB for a flush mount or part # A91BOB for a bracket for surface mount.

  • Option For Replacing A LP2PC Clear License Plate Light
    We do have an option for replacing your LP2PC clear license plate light. Unfortunately a direct replacement is not available, so instead we recommend the Optronics LED Trailer License Plate Light # LPL91CB. This will be virtually identical in size to the LP2PC light at 2-1/2" long x 1-1/4" wide x 13/16" deep. This light will require the grommet # A91GB for installation.

  • Difference Between Optronics Lights AL90RB and AL91RB
    The Optronics FLEET Count Mini Thinline Sealed LED Marker/Clearance Light # AL90RB has a single LED element while the similar Thinline LED Clearance and Side Marker Light # AL91RB has three LEDs for brighter output and it is submersible. Both can mount using either grommet # A91GB or bracket # A91BOB.

  • Are Optronics LED Lights Quality Lights
    Lights like the # MCL31AB and # MCL31RB are cheap but that is the nature of a small clearance light in this style. I wouldn't really expect better performance from any other brand. I know it happens, but we don't really see complaints about the lights burning out. Optronics lights are backed by a lifetime warranty on the LEDs so a light like your # BUL52CB is covered under and can be replaced. For the clearance lights I would try switching to the Thinline LED Clearance and Side Marker...

  • 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.

  • Clearance and Side Marker Light With Clear Lens and Red LEDs
    We do carry a number of options for clearance lights that have a clear lens and red LEDs, but the red equivalent of the Thinline LED Mini Clearance and Side Marker Light - Clear Lens - Amber # AL91CAB has a red lens as opposed to a clear lens; it is the Thinline LED Clearance and Side Marker Light # AL91RB. If you want to go this route you can mount it with Grommet # A91GB (recessed mount) or Mounting Bracket # A91BOB (surface mount) with Right Angle 2-Wire Pigtail # A46PB. For similar...

  • 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.

  • Mounting Options for Optronics LED Trailer License Plate Light LPL91CB
    The Optronics LED Trailer License Plate Light # LPL91CB does not include a mount but it can be used with either the grommet # A91GB or the Mounting Bracket # LP25SB and grommet together depending on the nature of the trailer. You can use butt connectors # 05731-5 to make the spliced connections.

  • 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.

  • Is there a Grommet for Peterson Clearance Light # M152A
    For a rubber grommet that will fit the Peterson clearance light # M152A you can use # A91GB. If you are looking for the plastic base we do not carry that particular model and in that case I recommend switching to light # A91AB and using bracket # A91BB with power wire # A91LW (the light grounds through one of the mounting screws with this light and bracket combination).

  • Hole Size Needed to Install Flush Mount Grommet for Trailer Clearance, Side Marker Lights
    The Optronics Flush Mount Grommet for A91 and AL91 Series Trailer Clearance and Side Marker Lights # A91GB, will fit a hole that measures 2-7/8 inches across and 1-1/2 inches tall. You will want to round the corners for a snug fit. This rubber grommet gives shock mount protection that extends the life of the lamp.

  • 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 inches...

  • 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.

  • Wiring Pigtail and Mounting Bracket Options For Installing Thinline LED Clearance And Marker Lights
    The Thinline LED Clearance and Side Marker Light # AL91AB require certain mounting brackets and plugs that are either already installed on the trailer or are available separately. A Right Angle 2-Wire Pigtail # A46PB will work with the Grommet # A91GB if you are looking to recess the light. Or Mount Brackets # A91OB and # A91BOB if you want to mount them on a surface with the wiring running behind the bracket. The Plug - Single Wire # A91LW is used for Mounting Brackets # A91BB and...

  • Does Optronics Mini Thin Line LED Marker/Clearance Light # AL191AB Use Grommet # A91GB
    Yes, the Optronics Mini Thin Line LED Marker/Clearance Light # AL191AB can be flush-mounted using the Optronics Flush Mount Grommet # A91GB. This PVC grommet will provide a degree of shock protection for the installed light and its rear opening allows easy access for wiring. If you prefer a surface-mount installation, you can instead use self-grounding mounting bracket # A91BB. The marker light # AL191AB has a 2-prong input on the back; you can use 6-inch pigtail plug # A46PB, or if you...
