Abstract: A self-powered, heat-activated LED exhaust tip assembly (10) that is comprised of three major elements: a cylindrical enclosure (12), a heat conducting sub-assembly (80) and an electronics circuit (130). The sub-assembly (80) consists of an external heat conducting plate (82), and an enclosure-internal heat conductive horizontal structure (110) that is attached to the plate (82) through a heat conductive vertical rod (98).
