A compact safety cone that can self-right when in use and be reduced to a compact size when not. The compact safety cone has a base, flexible means, and cover. The spring flexible means coils around the center of the base in decreasing diameters without overlapping. The compact safety cone has a substantially low center of gravity due to the weight distribution among its components. By design, the compact safety cone has a fast impulse response to direct (contact) and indirect (no-contact) perturbations and is capable of being run over or hit by a vehicle and “self-right” substantially immediately after the impact. When not in use, an integrated holding means conveniently and securely keeps the flexible means to the base. The holding means can be, e.g., a cover, lid, light, sign, mirror, box, case, hook, latch, strap, Velcro, pin, lock, etc. In some cases, an optional handle may be included.

1. A safety marker device, comprising:(a) a base having a circular opening; (b) a flexible means coiling over said base in decreasing diameters around the center of the opening; wherein the largest of said diameters is sufficiently larger than the diameter of the circular opening; and wherein said f
1. A safety marker device, comprising:(a) a base having a circular opening; (b) a flexible means coiling over said base in decreasing diameters around the center of the opening; wherein the largest of said diameters is sufficiently larger than the diameter of the circular opening; and wherein said flexible means having a degree of flexibility enabling a fast impulse response to direct and indirect perturbations; wherein said flexible means maintains in an original position in absence of said indirect and direct perturbations and flexes from said original position to a bent position in presence of any of said indirect and direct perturbations, wherein said bent position is characterized by having part of said flexible means bent up to a substantially horizontal position with respect to said base, and (c) a cover covering said flexible means; wherein said safety marker device has a substantially low center of gravity and is capable of self-righting substantially immediately after being run over by a vehicle or dropped on the ground; wherein the improvement comprises: (d) a holding means attached to said base for holding down said flexible means to said base in a reduced, compact position; wherein said holding means is selected from the group consisting of a cover, a lid, a light-emitting device, a sign, a mirror, a box, a case, a hook, a latch, a strap, Velcro, a pin, a lock, and combination thereof. 2. The improvement of claim 1, wherein said holding means is integrated to said base.3. The improvement of claim 1, wherein said holding means is attached to said base via a movable joint.4. The improvement of claim 3, wherein said movable joint is a hinge.5. The improvement of claim 3, further comprises a locking mechanism, wherein said movable joint has a spring mechanism that causes said holding means to self-erect upon release of said locking mechanism.6. The improvement of claim 1, wherein said lid is characterized as having a circular, triangle, square, rectangular, oval, square, or irregular shape.7. The improvement of claim 1, further comprises a securing means attached to said lid for securing said lid to said base.8. The improvement of claim 7, wherein said securing means is a latch, a lock, or a pin.9. The improvement of claim 8, wherein said lid is characterized as a self-erecting sign.10. The improvement of claim 8, wherein said self-erecting sign is attached to said base via a movable joint, wherein said movable joint comprises a spring mechanism that causes said lid to travel more than 45 degrees to an upright or display position upon release of said securing means.11. The improvement of claim 1, wherein said light-emitting device is attached to said base via a movable joint, said light-emitting device comprising a light source, a housing in which said light source resides, and a power supply for powering said light source.12. The improvement of claim 1, wherein said light emitting device further comprises a body member perturbing from one side of said housing, wherein said body member has a cross-sectional size that is slightly smaller than the smallest of said diameters of said flexible means such that, when in said reduced, compact position, said body member prevents said flexible means from moving.13. The improvement of claim 12, wherein said body member is hollow or solid and wherein said body member is characterized as a cylinder or a stick.14. The improvement of claim 12, further comprising a locking pin connected to said base for locking said light emitting device in said reduced, compact position.15. The improvement of claim 1, further comprising a handle integrated or attached to said base.
