In a vehicle lamp control device, a control unit is configured to a) hold a road surface angle reference value and a vehicle posture angle reference value in a volatile manner, b) generate an optical axis adjusting signal using a vehicle posture angle in response to variation in a total angle during the stop of the vehicle, c) avoid generating or outputting the optical axis adjusting signal or output an optical axis holding signal, and hold a road surface angle as a new reference value, in response to variation in the total angle during travelling of the vehicle. The control unit, in response to receiving the turn-off signal of the switch, d-1) writes at least the road surface angle reference value in the storage unit or continues to execute the step (c) while delaying the step (d-1).
