The invention discloses a multilevel display automobile brake tail lamp device. An intermediate circle of lamps are fixed within an outer circle of lamps, and an inner circle of lamps are fixed within the intermediate circle of lamps. By installing multilevel control switches on a brake mechanism, the multilevel display of brake tail lamps is achieved. In case of light brake, an outer circle of push-button contacts of each switch are in contact in the first place, and the outer circle of lamps illuminate; the brake is continued to be trodden, and the intermediate circle of lamps illuminate; in case of emergency brake, all the three circles of lamps illuminate. According to the first embodiment, the push type switches are used, distances among the tree groups of contacts get larger sequentially, and with the brake treading force getting larger, the outer circle, an intermediate circle and an inner circle of push-button contacts are switched on in sequence. According to the second embodiment, rotating disc type switches are used, rotating discs rotate along with a rotating shaft of a brake pedal, with the brake treading force getting larger, rotating angles are increased, and the outer circle, an intermediate circle and an inner circle of contacts are switched on in sequence through arc-shaped contacts on the rotating discs. According to the difference of the brake treading force, the multilevel display of the tail lamps is achieved, the effect of clearly demonstrating the brake force of an automobile in front is achieved, a driver in an automobile is reminded to take corresponding brake measures in time, and the occurrence of rear-end accidents is reduced and avoided.
