MONEY WELL SPENT!!!
My old aftermarket one was yellow and icky. I did my research and decided to go with this and I don’t regret it. I put some silicon to be sure it doesn’t leak. Highly recommend!

Works as Advertised
The only thing that caught me off guard was just how much brighter it is (That is good). No more replacing bulbs is nice too.

Update an F150's Looks
The light itself is very simple to install and it really updates the back of the truck cab. The LEDs are plenty bright. Instructions could use a small improvement. For the cargo light, the orientation of the plugs is important (not mentioned in the instructions); red from the light to grey on the truck harness.

Looks great but…
Install is a breeze and it’s way brighter than stock. It does leak however. Gonna need to put some better gasket/seal on it.
