Abstract

A two-step control signal device is mounted on an automobile and has a turn signal, a U-turning signal and a two-step control circuit. The turn signal has base having a recess and a turn light. The turn light is mounted in the recess. The U-turn signal is mounted on the base and has a circuit board and multiple U-turn lights. The circuit board is mounted on the base and is connected electrically to the turn light. The U-turn lights are mounted electrically on the circuit board around the recess. The two-step control circuit is connected electrically to the turn signal and the U-turn signal, operates the turn signal when in a turn step and operates simultaneously the turn signal and the U-turn signal when in a U-turn step. The operating U-turn signal warns other automobiles nearby that the automobile is making a U-turn.

Claims

1. A two-step control signal device is mounted on an automobile and comprising:

a turn signal having

a base having an outside surface and a recess defined in the outside surface and having an inner surface;

a turn light mounted in the recess; and

a screen being transparent, mounted on the inner surface of the recess in the base and covering the turn light;

a U-turn signal mounted on the base; and

a two-step control circuit connected electrically to the turn signal and the U-turn signal, operating the turn signal when in a 90 degree turn step and operating simultaneously the turn signal and the U-turn signal when in a U-turn step.

2. The two-step control signal device as claimed in claim 1, wherein the U-turn signal has

a circuit board mounted on the outside surface of the base around the recess and connected electrically to the turn light;

and

multiple U-turn lights mounted electrically on the circuit board and arranged around the recess.

3. The two-step control signal device as claimed in claim 1, wherein the U-turn signal is a luminescence board mounted on the outside surface of the base around the recess.

4. The two-step control signal device as claimed in claim 1, wherein the two-step control circuit has

a power source being in series connection with the turn signal and the U-turn signal and a sequence of the series connection is the power source, the turn signal and the U-turn signal;

a node connected electrically to the turn signal and U-turn signal and located between the turn signal and U-turn signal;

a first normally open terminal connected electrically to the node;

a second normally open terminal connected electrically to the U-turn-signal;

a common terminal connected electrically to the power source;

a normally closed terminal is isolated; and

a switch having

a first end connected electrically to the common terminal; and

a second end selectively connected electrically to one of the first normally open terminal, the second normally open terminal and the normally closed terminal;

wherein;

when the two-step control circuit is in the 90 degree turn step, the second end of the switch is connected electrically to the first normally open terminal; and

when the two-step control circuit is in the U-turn step, the second end of the switch is connected electrically to the second normally open terminal.

5. The two-step control signal device as claimed in claim 1, wherein the turn signal operates with the turn light shining intermittently.

6. The two-step control signal device as claimed in claim 2, wherein the U-turn signal operates with the U-turn lights shining intermittently.

7. The two-step control signal device as claimed in claim 2, wherein the U-turn signal operates with the U-turn lights shining as a moving looped path.

8. The two-step control signal device as claimed in claim 3, wherein the U-turn signal operates with the luminescence board shining intermittently.

9. The two-step control signal device as claimed in claim 2, wherein the turn light is a bulb and the U-turn lights are light emitting diodes.

10. The two-step control signal device as claimed in claim 2, wherein the turn light is a light emitting diode and the U-turn lights are light emitting diodes.

11. The two-step control signal device as claimed in claim 1, wherein a brake light is mounted in the recess in the base.

12. The two-step control signal device as claimed in claim 11, wherein the screen of the turn signal is tinted with a first color and further has a sub screen tinted with a second color and corresponding to the brake light.

13. The two-step control signal device as claimed in claim 12, wherein the brake light is a bulb.

14. The two-step control signal device as claimed in claim 12, wherein the brake light is a light emitting diode.
