  • Lighted exhaust pipe extension
    Patent number: 6663269
    Abstract: A lighted extension for an exhaust pipe is provided which has an elongated substantially cylindrical collar including a first portion disposed coaxially around an exhaust pipe and a second portion that extends beyond an exhaust pipe end of the exhaust pipe. A plurality of fasteners is disposed substantially radially around a circumference of the first portion to secure the collar to the exhaust pipe. A cap with a plurality of lights displayably disposed in the cap is removably disposed over an end of the second portion. A perforation disposed in a wall of the second portion, communicating with the exhaust pipe, allows exhaust diverted by a baffle disposed within the second portion medially between the perforation and the cap to pass through the perforation, substantially avoiding the lights.
