Abstract: A structurally improved detachable front panel for car stereos is disclosed. The panel is detachably mounted to the fixed main body of a car stereo and has an improved structure suitable to make the panel be selectively used as an emergency lamp. The panel has lighting means, switching means for turning on or off the lighting means, and power supplying means for supplying electric power for the lighting means. A panel casing receives the front panel separated from the stereo's main body and has a means for directly operating the switching means of the panel at the outside of the casing so as to turn on or off the lighting means when using the panel as a lamp.
