      Cab light

      The piece is nice and works great. Easy install. Only issue is gasket that is supplied is rather small and you risk the possibility of having leaks. I applied clear non yellowing silicone around mine then installed it and then sealed around the top. I wish i would have taken pics of the gasket. All in all its still a great piece to add to your ride.

      Looks great

      I had my OEM start leaking and looked for a black alternative. This worked great, so far no issue with the wiring, had zero problems installing, and product was full quality.

      3rd Brake Light

      Light looks very nice. LED’s worked good and lit up bright. Not happy with the fiitment though. Could hardly get the screws started and didn’t even get them close to snug and it cracked the lense. I’ve installed multiple third brake lights and never had this happen to me.
