摘要： A hood latch assembly (10) has a housing (14) having a mouth (13). A ratchet (16) is pivotally mounted within the housing (14) to cooperate with the mouth (13) to pivot between an open, a secondary closed and a primary closed condition for receiving, engaging and cinching a keeper of a striker (80). The ratchet (16) is biased to the open condition. A pivotally mounted primary pawl (18) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the primary closed condition. A pivotally mounted secondary pawl (62) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the secondary closed condition. The secondary pawl (62) has a release lever (20) which rotates between a deployed position and a retracted position. As the ratchet (16) engages the striker (80), the ratchet (16) will rotate in a latching sense from the open condition to the secondary closed condition. As the ratchet (16) further rotates from the secondary closed to the primary closed condition, fully engaging the striker (80), the secondary pawl (62) follows the ratchet (16), allowing the release lever (20) to rotate from a deployed position to a retracted position. Upon release of the primary engagement by disengaging the primary pawl (18), the ratchet (16) will rotate from the primary closed to the secondary closed condition. The secondary pawl (62) will follow the ratchet (16) rotating the release lever (20) from the retracted position to the deployed position. The operator then manipulates the release lever (20) to release the ratchet (16), allowing the ratchet (16) to rotate from the secondary closed to the open condition. The hood latch (10) has a light (82) which is operable responsive to movement of the release arm (20) moving from the retracted position and the deployed position. Changes of the hood latch (10) between the primary closed condition and the secondary closed condition will open and close the switch (78). The switch (78) is disposed between a light source (82) mounted to illuminate the hood latch (10) region and a source of electrical power. Opening and closing of the switch (78) will responsively illuminate the light (82).
