## Abstract

A light assembly mounted in recess of a seat post of a bicycle is provided with a push button moveably mounted on a mouth of the recess and including a bossed hole on a rear surface; a resilient conductor fastened in the bossed hole; a controller circuit fastened in the recess and including two spaced contacts spaced from the conductor in a non-depressed position, the contacts being electrically connected to the controller circuit; LEDs disposed on a front surface of the controller circuit facing the rear surface of the push button; and a battery mounted to a rear surface of the controller circuit and electrically connected to the contacts. A pressing of the push button electrically connects the conductor to the contacts so that an electric energy is supplied from the battery to the LEDs for illumination via the contacts, the conductor, and the controller circuit.

## Claims
