Peterson 844 Low Profile Combination LED Tail Light Dimensions

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 circuit board is sealed, which means that water will not damage the diodes or circuit board.


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.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

great price, long lasting brightness

Purchased these in April, installed in May. Second trip I made with the trailer in July, the lens fell off one light. No damage, it just fell off.
Neither E-trailer, nor Peterson will warranty the light.
I think it's the last time I spend money with either of them.

I wouldn't know why they choose not to warranty the whole unit. I would recommend reaching out to them directly to see if they can work with you on this.

I used these to replace the tail lights on my utility trailer. They are bright and because they are LED they will not require any attention. I look forward to many years of reliable service.

Perfect replacement for my damaged tail light on our new Timpte 720 aluminum car hauler. Shipping was very quick and packaging was perfect. Thank you for the great service.

  • Troubleshooting Trailer Brake and Turn Signal Not Working
    Hey Edward! That looks like the Peterson LED Combination Tail Light # M844 and # M844L on your trailer. The lens is held on by four tabs which can be seen in the attached photo of the replacement lens # 844-252. It would also be worth double checking your ground connections since a loose ground is often the issue with symptoms like these. I would check trailer connectors as well to make sure no corrosion is present. If all of that checks out it could be a short in the wiring or even loose...

  • Looking For Square Tail Lights Made In The USA
    Hello Mike, thanks for reaching out. The Optronics lights like the # STL9RB you mentioned are made in Taiwan. We do have a very similar light that is made here in the USA, the Peterson LED Combination Tail Lights # M844L for driver side and # M844 for the passenger side light.

  • How Does Lens of Peterson LED Combination Tail Light # M844L and # M844 Remove
    On the top and bottom of the Peterson LED Combination Tail Light # M844L and # M844 there are 2 indentations in the black plastic housing that you'll need to insert a small slot screwdriver into to push down and release the tabs of to pull the lens off. In the picture I attached you can see the two slots pointed out.

  • Trailer Wiring For a 2020 Acura RDX and Lights For Rebuild On Utility Trailer
    Since your 2020 Acura RDX did not come with trailer wiring you are going to need the T-One Vehicle Wiring Harness # 118804. Then you will be able to connect and pull your trailer with a Ball Mount # DT49MR. For your utility trailer if you are looking to install new Tail Lights # M844 & # M844L you might consider changing the Wiring # A25W2GWB harness as well if it is damaged. We also have the Fender Light # MCL180ARB if your trailer uses these style lights.

  • Rebuilding 5 X 8 Utility Trailer and Wiring Trailer To Have 7-Way Connector
    First here are some parts I am going to recommend for fixing up your trailer. The Taskmaster 4.80R12 Radial Trailer Tire # TT48012C is a great option since it has a radial versus bias construction. This will give you better highway characteristics and increased tread life. For the wiring the Wiring Kit # HS381-9000 will give you a 7-way and junction box along with connectors for inside the box so you are not trying to find all the right sizes. The 4-way Trailer Harness # A25W2GWB is a great...

  • Will Trailer Taillights Flash if Emergency Flashers are On
    Hey Mike, yes when you turn on the emergency flashers of your vehicle the trailer taillights will both flash since that circuit is connected to the stoplight circuit.
