I'm on my third one. The first one lasted so long it just got worn out. The second one was broken during a tow, rear hitch made some contact during loading. And now the third one. This is the only hitch cover light that works to my expectation. It works only as a brake light and running light. No awkard flashing in the center of my vehicle like all the other ones do (yes, even the LED ones do). This light is the only one that outputs usable visual light. All other LED variants are too dim to be effectively seen. A couple modifications I made to this light for better operation are: Tape off the light bulb socket and outer plastic of the unit with masking tape. Spray paint the interior with shiny silver metallic paint to give it more of a reflective result. Let dry and remove tape. No idea why the interior is left black, for less light reflection and output. This quick mod provides more light output. Another mod is also an easy one. Take out the 1157 bulb (27w/8w) and install a 2057 bulb (27w/6w). This will give your hitch cover more of a step up in brightness from running light to brake light for more attentive contrast. This also helps in overheating. The 1157 burns hotter with running lights on, very marginal, however it works to help reduce from the plastic melting at the top without the brakes on. The brake output is the same at 27w, it will just be slightly dimmer with runnings lights on. The bulbs are interchangeable.
