The invention discloses a front car door lock with a signal prompt function. The front car door lock comprises a signal lamp and a micro switch used for controlling switching on and switching off of the signal lamp. A ratchet shaft and a pawl shaft are arranged on a lock body in parallel, a ratchet is sleeved on the ratchet shaft in a positioned manner, a pawl and a pawl linkage plate are sleeved on the pawl shaft in a positioned manner, the ratchet and the pawl are matched to form a linkage mechanism, the pawl linkage plate forms a linkage mechanism with an internal opening mechanism and an external opening mechanism, and the micro switch is arranged on one side, back to the pawl, of the ratchet. The front car door lock has functions of external opening, internal opening, locking and signal prompting; through the micro switch arranged inside the lock body, when a lock plunger is not locked, the micro switch is normally closed, and an electric circuit of the signal lamp is connected; when the lock plunger is locked, the lock plunger can drive the ratchet to rotate by a certain angle so as to enable the ratchet to trigger the micro switch, and the electric circuit of the signal lamp is disconnected. An electrical appliance is separated from machinery, and the front car door lock is convenient to mount and rapid to demount.
