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.

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

Light is still working great, would buy again if the need arises.

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.


Comments
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.

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


Comments
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.

The product was exactly what I needed- I searched it using the part number on the broken part. etrailer.com had exactly the thing. The website was very simple and uncluttered, allowing me to find the item and purchase it without hassle. Also, the tracking was so easy and seamless- I was sent a link and when I clicked on it the tracking came up on etrailer.com's domain without having a bunch of extra steps. Nicely done, etrailer.com!

I changed out my original Wesbar incandescent trailer running lights to LED. The thin line series snapped right into the original base. Looks great and they are water proof.

After one year the lights are still bright and the wiring is still in great shape. One of the best made replacement side markers I’ve ever purchased.

Exactly what I needed for my trailer. Arrived as advertised. Fantastic customer service!!

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.

Light was used on an EZ-Loader trailer. Exact fit. Works as expected.

I bought several of these, and (1) of them quit working almost immediately. I should have returned it, but never got around to it, so I'll have to order another one.

Thank you for your review. These have a lifetime warranty on the LEDs. Please note that does not mean your wiring. Customer Service will contact you within 24-48 hours.

Thank you so much. Had to replace Trailer lights on my boat, couldn’t find lights anywhere. Was leaving in 6 days. You had everything I needed and had them shipped to me in time for my trip. And the order was correct with no issues. Thanks again

I was very concerned about getting position lights that would be a comparable replacement for those on my 20 year old car hauler. Saw these, checked the measurements, and prayed they would fit. I was very pleased to find these were the exact replacements and a simple R and R (remove and replace) had them up and running in less than 5 minutes. The LED replacements are so much brighter than my older incandescent bulbs. Ordering was simple, quick, and pain free. Great job etrailer!

Easy to install. No additional fit up necessary.

by:

Best light. I put new standard lights on and the first trip the bulb vibrated out. Since the light was sealed, I could not reinstall the bulb, so it was useless. Put these LED light in and they fit perfectly, connected exactly the same, we’re bright, and handled bumpy gravel roads without issue. Still functioning perfectly and I will always use these from now on.

I had a heck of a time finding this side marker light and as it fit into a specific rubber mount (by another manufacturer) which in turn fit into a specific opening in the trailer's fender and the original light was marked by yet another manufacturer (who no longer makes this model) I was VERY glad to discover Optronics made a perfect replacement. It was exactly as described and fit perfect! The best part is it lights up beautifully! Thanks etrailer, you saved the day!!

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.

  • Upgrading Lights on 2000 Tracker PT175 Trailer to LED
    We do offer a wide variety of replacement lights for trailer but since trailer manufacturers don't keep a record of what they use on trailers I would need some pictures of the lights you are wanting to replace along with some measurements so I can be sure to recommend the correct parts.

  • Will LED Clearance Light Work With One Wire
    Yes, the Thinline LED Clearance and Side Marker Light - Submersible # AL91AB will work with your single power wire, as it uses a 2-wire (one for power, one for ground) pigtail or 1-wire pigtail with a self-grounding bracket. 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.

    In order to determine if the Thinline LED Clearance and Side Marker Light # AL91AB will fit your trailer you simply need to measure your light and see if it matches; this light is 2-1/2" long x 1-3/16" wide x 7/8" deep. It is also a great option because it can be either recess or surface mounted. For a surface mount you will use Self-Grounding Mounting Bracket # A91BOB with Plug # A91LW. For a recess mount you will use Grommet # A91GB with Right Angle 2-Wire Pigtail # A46PB. I...

  • Replacement Rectangular Amber 2-1/2 Inch Long by 1-1/2 Inch Wide Clearance Lights
    The “SAE P2PC 98” you provided is a code used by the department of transformation and will not have any bearing on the correct replacement. In order to determine the correct replacement I would need you to either A) remove the lens and find the part number inscribed on the base or B) send me a dimensional photo of the light.

If your lights have different dimensions then I've linked our selection of replacement amber lights that you can filter through, or you can take some measurements and send those in with some close up pictures of the lights that I can use as a reference.

  • 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...

  • 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...
