  • Truck Lite 15250Y
  • Grote 47083

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.

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. 566618


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 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!! 147552

Still working fine after being submersed numerous times.

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. 256594

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!! 73760

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! 676851

by:

Poor/incomplete product description. These are obviously replacement lamps for some type of fixture. These are not meant to stand alone with wire pigtails that you can use to replace existing trailer lights. I'll have to return these now. 672628


Comments

As mentioned in the product description above, the lamps are mounted using the pigtails and surface or grommet mounts which are sold separately. These items arent included because the mount and pigtail needed will depend on how youre mounting the lamp.

Ask the Experts about this Optronics Trailer Lights

Do you have a question about this Trailer Light?


  • 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. Your other option to mount this light is to use Self-Grounding Mounting...

  • Ways to Convert Trailer to LED Type Lighting
  • 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...

  • 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.

  • Is the Peterson Clearance and Side Marker Trailer Light Offered with Female Terminals
  • It sounds like you are looking for the Thinline LED Clearance and Side Marker Light part # AL91AB which has female terminals in the rear but a better option for you would be to just replace the pigtail with the Peterson Right Angle 2-Wire Marker Light Plug part # 153-49.

  • How to Select Replacement Trailer Lights
  • Trailer light part numbers are usually found on the base of the light, rather than on the light lens. If you can find a part number on the base you can search our site by entering that number into our search box. The codes on a lens are often DOT numbers rather than actual manufacturer part number. We do carry many brands of trailer lights, including lots of Optronics products, and the page I linked for you will let you select the type, size, brand and color of light you want. All...

  • 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.

  • License Plate Holder and Replacement Lights for Exiss Horse Trailer
  • We have a few types of license plate holders to choose from and you can see all of them on the linked page. You might prefer one design over another for your Exiss horse trailer, such as the CE Smith Tread Plate design # CE26053A As for trailer lights we have products that are direct replacements for many popular OEM lights, and we also offer both basic incandescent bulb lights as well as brighter high-efficiency LED types that draw less power.

  • How to Determine if Amber Clearance Light Will Work on Trailer
  • 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...

  • 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...
