An illuminated foot or highway peg for a motorcycle is disclosed which is pivotally mounted to the underside of each of the floorboards of a motorcycle and which is selectively pivotally movable between a retracted position and an extended position. A ball detent mechanism yieldably maintains the foot peg in its retracted and extended positions and also enables the foot peg to break away to move towards its retracted position should it strike a foreign object while in its extended position.
