Features to know about

Reliable Lighting for Wider Trailers: 7-Function Combination Tail Light

For trailers over 80" wide, you need lighting that covers every safety and legal requirement. This Peterson square incandescent tail light does it all in one unit—stop, turn, tail, rear and side reflex reflectors, side marker, and license illumination. The built-in reflectors mean you don’t have to mount separate ones, keeping the setup clean and simple. It’s DOT compliant and uses a standard 12V DC system for easy hookup and dependable performance every time you tow.

Straightforward Installation: Stud Mount with Quick-Connects

If you like wiring that doesn’t fight you, this one’s simple. The PM444L uses fixed mounting studs spaced 2" center-to-center, so it bolts right up without fuss. Quick-connect wire inserts let you push the wires straight in—no crimping or special tools needed. It even grounds through the mounting hardware, making the wiring cleaner and reducing connection points that could fail down the road.

Flatbed trailer over 80 inches wide with combination tail lights installed at rear corners for proper clearance lighting compliance.

Built to Last: Durable Polycarbonate Housing with Weathertight Seal

Trailering often means bouncing along roads or sitting out in the elements. The tough polycarbonate housing and screw-on lens are designed to handle it. Included foam gaskets help form a weathertight seal between the light and your trailer body, keeping out dust and moisture. That protection helps the incandescent bulbs stay bright and reliable longer, even when the weather turns bad.

Serviceable Design: Replaceable Bulbs for Long-Term Use

Unlike sealed lights that have to be tossed out when a bulb fails, this one’s easy to maintain. The Stop/Tail function uses an 1157 bulb and the Side Marker uses a 194/193 bulb—both common types you can swap in minutes with no special tools. When everything else about your trailer is built to last, it’s nice when the lights are too.

Bright Rear Coverage: Clear License Plate Lens Included

Rear visibility matters for both safety and compliance. This driver-side model includes a clear lens section that shines directly onto your license plate so it stays visible at night or in low light. Two additional ports also let you tie in extra lights if needed for even more coverage. It’s a complete lighting solution made for wide trailers that need to be seen clearly from every angle.

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.
by:
Used these to replace the LED lights that came on my trailer. They provide a much softer light than the LED and have replaceable bulbs so I won't get stranded on a trip when the LEDs go out. In most states, the police are allowed to pull you over and ticket you if a single diode goes out in an LED light.

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 etrailer.com.

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!!!

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.

  • 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...

  • Replacement Lens For Peterson Light 440-15
    Hi Jack! The 56-15R did indeed use screws, but it looks like that was phased out a few years. The Replacement Side Marker Lens for Peterson Tail Lights for Trailers Over 80" Wide # 444-151R is a direct replacement for the Peterson 440-15 and does use the snap in tabs, so it sounds like this would be what you are looking for. As a side note, we do have the full light as well. I have both driver and passenger side lights listed below, if you ever need them: Peterson Tail Light for Trailers...

  • 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...

  • 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.

  • 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 Tail Light Lenses for a Roadmaster 8000 Tow Dolly
    Yes you can. It looks like your Roadmaster 8000 tow dolly uses Peterson light # PM444 for the right side and # PM444L for the left side. The replacement side lens for these lights is # 444-151R. The replacement main lens is # 440-15R.
