Yes, an anti-theft light can drain the battery, albeit very slowly. The anti-theft light or security indicator light is designed to use a minimal amount of power, primarily when the vehicle is off to indicate the system is active. However, if your vehicle is left unused for long periods, this continuous usage, along with other parasitic drains, can contribute to battery depletion. To maintain battery health, it's advisable to start and run your vehicle regularly, or consider a battery maintainer for prolonged inactivity.
