Yes, the Ring Doorbell light can light up when it is recording. The light feature is designed to provide a visible indication that the Ring Doorbell is actively capturing video footage. When motion is detected or someone rings the doorbell, the light can illuminate to serve as a deterrent and let people know they are being recorded. This added visibility acts as a security measure and can help discourage potential intruders or unwanted visitors. Additionally, the light can also serve as a handy visual cue for homeowners, indicating when the Ring Doorbell is capturing important events.
