Claims: What is claimed is:

1. A traffic signal marker comprising:

an unbreakable elongated light transmitting tube containing two manually miscible chemical reactants;

said reactants, when mixed, being effective to emit light from said light transmitting tube;

a base member securedly receiving one end of said tube;

said base member comprising first and second support members;

said support members being arcuate in form and having upwardly facing concave surfaces and bottom surfaces for contacting a horizontal surface; and

each said support member having upturned peripheral ends with attached resilient downwardly projecting outboard stabilizing prongs, said bottom surfaces and said stabilizing prongs coacting to contact a supporting surface at approximately right angles thereto and to maintain the light tube in an upright position when the signal marker is deployed on the horizontal surface.

2. The device of claim 1 wherein said support members comprise an uppermost member and a lowermost member and said uppermost member comprises a chamber for receiving the end of said tube; and

lock means including upstanding abutment means on said uppermost support member and tubular retaining means fitted over said upstanding means for retaining the end of said tube in said chamber.

3. A traffic signal marker comprising:

an unbreakable elongated light transmitting tube containing chemiluminescent reactant material means;

a base member securedly receiving one end of said tube;

said base member comprising first and second support members;

each said support member being arcuate in form and having upwardly facing concave surfaces and bottom surfaces for contacting a horizontal surface when deployed thereon, each end of the upwardly concave surfaces of the support members having a downwardly projecting resilient arm member;

said support members being rotatably fastened together at their lower extremities and having interlocking facing surfaces;

each support means being relatively movable from a co-linear storage position to an orthogonal deployment position whereat said interlocking facing surfaces effectively lock the two support means together.

4. The device of claim 3 wherein each of said first and second support members are arcuate in form having upwardly facing concave surfaces: and

each said end of the support member having peripheral ends with attached resilient downwardly projecting outboard stabilizing prongs adapted to contact a supporting surface at approximately right angles thereto when the signal marker is deployed.

5. The device of claim 4 wherein said support members comprise an uppermost member and a lowermost member and said uppermost member comprises a chamber for receiving the end of said tube; and

lock means including upstanding abutment means on said uppermost support member and tubular retaining means fitted over said upstanding means for retaining the end of said tube in said chamber.
