ABSTRACT:
An LED display collision warning circuit for vehicles is provided. This circuit causes an LED display installed at tail of a vehicle to show warning indications. The LED display has six lamps which group into three display units with each unit consisting of two laterally symmetrically positioned lamps. These three display units show different warning indications in response to signals from a door-actuated circularly lighting and extinguishing circuit, a brake-actuated alternately flashing circuit, or a headlight-actuated night distance detection circuit so as to effectively prevent collisions and accidents.
