The present invention is directed to a safety light, such as a barricade lamp. The safety light comprises a light member and a power source comprising a non-rechargeable battery source and a rechargeable battery source. A solar cell array is also included and is adapted to recharge the rechargeable battery source. A battery monitor and a power control processor are configured to control the supply of power to the light member by causing the rechargeable battery source to power the light member until the charge level of the rechargeable battery source falls below a certain level, at which time the power control processor causes power from the non-rechargeable battery source to power the light member.
