A lamp system for traffic lane indication using a navigation link may include a multi-function sensor sensing an environment and a line in front of a host vehicle, a line lamp generating and outputting a prediction line at a location corresponding to a line of a road, a navigation device providing location information of the host vehicle, and a vehicle controller predicting a forward line based on a line sensed by the multi-function sensor, and the location information of the host vehicle provided by the navigation device and controlling the line lamp to output the prediction line to follow the predicted forward line.
