Please make sure you have a 2" rounded square hitch receiver that matches the rounded square opening of the hitch light.

Leaving an empty unused hitch receiver can build up dirt and debris from the road. Not to mention it looks dull and boring. Add a functional feature which provides style and safety using the latest LED technology.
Unlike current 9-LED brake light w/ bright mode only, our 15-LED has brake AND running tail light; will not blink with turn signals (only)
Installation Tip: when you plug in this adapter, pay attention to the orientation. Push in the adapter from an angle starting from the pin in the red arrow. If you have difficulty install the adapter, you can always bend the pins slightly during the plugging process.

FAQ:

Q: Why does the LED brake light fits the tow hitch, but feels loose?
A: The tow hitch cover is only secured by the tow hitch lock to make sure that it does not fall off, so the lock is not completely tight. There is already some foam in the inner side of the tow hitch cover, but if you feel that you would like the tow hitch cover to fit more snug, you can always add some foam to hold the tow hitch cover in place.

Q: What if the LED brake light wiring is not long enough for my vehicle?
A: The length of the wire for the LED brake light is designed to work for most trucks and SUVs with a tow hitch. In some rare cases, if the wiring is too short, you can extend the wires. Cut the adapter wires and extend the wiring.

Q: Why does the LED brake light not light up after I plugged in the adapter?
A: In some rare cases, the vehicle's positive/negative is reversed. The LED assembly is polar sensitive, the polarity reverse causes LED to not light up. This is rare but can be fixed. Take the adapter and cut the wires. Flip the wires to reverse the polarity.

Q: Why does a message asking me about a trailer mode pop up on my dashboard computer after I installed the rear LED brake light?
A: Newer trucks like the 2018 Ford F-150 can detect if the power socket under its tailgate is in use. Plugging in the 15-LED brake light will trigger this message which is completely normal. You may either disable trailer mode when the prompt comes up or ignore the message
