Optronics # ST3RB

Peterson 444L Over 80 Inch Trailer Combination Tail Light Dimensions

Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.

To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Exact replacement item …. Ordering was easy and shipment was handled the same day


works fine and it is a Peterson.


Great product at a good price. Extremely fast shipping...Great Service. Thanks!!!!


This has got to be the worst lights for a trailer. I purchased a brand new trailer with these lights and less than a hundred miles down the road the side red covers fell off. I had to purchase a complete light kit just to replace the covers and they lasted about just as long. My suggestion is if and when they fall off as they surely will just buy an entirely different light and replace them. I don't think these lights would hold together on a bicycle much less a trailer.


Exactly what I ordered and fit like a charm. I was blown away with the speed of shipping! Was supposed to arrive Jan 19 but came the 15th instead!


Each and every time I use etrailer I have always been completely satisfied! This time was no exception, this tail light was exactly what I wanted.


The tail light was delivered as promised. An exact replacement at a very good price and received in a few days. I will definitely purchase future items needed from


Received the product in perfect condition. May have been a simple thing for some but as a 67 year old Lady with no experience, I was able to install it easily and it has been working perfectly ever since. Thank you etrailer!!!


Received product in a timely manner. Did not have instructions but easy enough to figure out the proper wiring. I would recommend this product.
Thank you.


Our order appears to be in good shape, though we haven’t installed it (light) on our trailer yet—assuming it will work just fine. (We hope!) It all looks in tact at any rate.


The product is exactly what I needed and ordered. Price was good and product holds up great a year later. Very happy!

Great! Great replacement

  • Part Number For Peterson Driver's Side Tail Light That Matches PM444
    You are correct, part # PM444 is the Peterson Tail Light for Passenger side. The driver's side Peterson Tail Light is part # PM444L. The passenger's side light has 6 functions: stop/turn/tail, side marker, rear clearance, side reflector, and rear reflector. The driver's side light is designed with 1 extra function, a light on the bottom that shines onto the license plate.

  • Troubleshooting Trailer Wiring on 2008 Snowbear 6x8 Utility Trailer
    The only difference between the run-of-the-mill 4 pole trailer connector and the one you describe is the fact that the one on your trailer split the running light circuit into two legs, one for the drivers side, using the yellow/brown wire and one for the passenger side, using the yellow/green wire. No worries about the length of your email, the more information, the better. When you mention that functionality of the lighting system changes with the running lamps on, it's a red flag that...

  • Availability of Side Replacement Lens # 440-15R Left Side
    I spoke with my contact at Peterson and she said replacement lens part # 444-151R is the correct replacement lens for both right and left side lenses. I went out to the warehouse to measure this light for you and found the dimensions to be 2-3/4 inches long x 2 inches wide x 1-7/16 inches tall. I have included a photo of the lens showing the dimensions for you to check out. The # 444-151R lens is a direct replacement for the Peterson Over 80 Inches Wide Trailer Tail Light # PM444L and...

  • Replacement Light and Lenses for Peterson Trailer Tail Light 444-151
    There are a few Peterson lights that have the 444 designation. Replacement lens # 444-151R should be the correct lens for your 444 151 light. The main tail light lens is # 440-15R. For the whole light assembly use # PM444 for the right or # PM444L for the left.

  • LED Replacement Lights for Peterson M444
    We do have a couple of really good options for you to replace your Peterson # # PM444L and # PM444, but you do have a keen eye because the Tail Light Kit # TLL16RK will not work with the 2-1/4" spacing you have. One of the lights would interfere because it is too long overall and the back of the light cannot be rotated. Instead, for a couple of similar options that have 2" on center spacing and the needed space for you to mount them I recommend checking out the LED Combination Tail Light...
