Abstract

An apparatus can include a first light bar that includes a first light guide that can reflect a first light from a first source. The apparatus can include a second light bar that includes a second light guide that can reflect a second light from a second source. The first light bar can couple with the second light bar.

First claim

What is claimed is:

1. An apparatus, comprising:
a first light bar comprising a first light guide configured to reflect a first light in a first direction from a first source, the first source coupled with a first printed circuit board; and
a second light bar comprising:
a divider configured to define a plurality of segments of the second light bar; and
a second light guide configured to reflect a second light in a second direction from at least one second source to the plurality of segments, the at least one second source coupled with a second printed circuit board;
a cover at least partially surrounding the divider and the second light guide, the cover having a first transparent portion, a second transparent portion, and an opaque portion coupled with and disposed between the first transparent portion and the second transparent portion to provide a patterned display of the second light;
the divider extends along the second light guide outward beyond an end surface of the second light guide in the second direction towards the cover;
the second printed circuit board disposed between the first light guide and the second light guide; and
the second printed circuit board configured to:
control the at least one second source to emit the second light via the plurality of segments to produce a linear display to indicate a status of one or more batteries of a vehicle.

2. The apparatus of claim 1 , comprising:
the first printed circuit board to cause the first source to emit the first light towards the first light guide to reflect the first light from the first source.

3. The apparatus of claim 1 , comprising:
the first printed circuit board to cause the first source to emit the first light in a third direction towards the first light guide.

4. The apparatus of claim 1 , comprising:
the first light bar is configured to function as at least one of a daytime running light or a position light;
wherein the status of the one or more batteries of the vehicle is a charge status of the one or more batteries of the vehicle.

5. The apparatus of claim 1 , comprising:
the first light bar comprises a tail light of the vehicle;
wherein the linear display is a charge indicator light of the one or more batteries of the vehicle.

6. The apparatus of claim 1 , comprising:
the divider configured to at least partially block light between a first segment of the plurality of segments and a second segment of the plurality of segments.

7. The apparatus of claim 1 , comprising:
the first transparent portion and the second transparent portion of the cover interlocking with the opaque portion of the cover.

8. The apparatus of claim 1 , comprising:
the cover includes a material comprising at least one of a micro texture, a pill texture, or a vertical line texture.

9. A method, comprising:
emitting a first light from a first source coupled with a first printed circuit board;
reflecting, by a first light guide, the first light in a first direction;
emitting a second light from at least one second source coupled with a second printed circuit board;
reflecting, by a second light guide, the second light to a plurality of segments defined by a divider;
the second printed circuit board disposed between the first light guide and the second light guide;
controlling, by the second printed circuit board, the at least one second source to emit light via the plurality of segments to produce a linear display to indicate a status of one or more batteries of a vehicle;
the divider extends along the second light guide outward beyond an end surface of the second light guide in a direction towards a cover; and
the cover having a first transparent portion, a second transparent portion, and an opaque portion coupled with and disposed between the first transparent portion and the second transparent portion.

10. The method of claim 9 , comprising:
causing, by the first printed circuit board, the first source to emit the first light towards the first light guide to reflect the first light from the first source.

11. The method of claim 9 , comprising:
causing, by the first printed circuit board, the first source to emit the first light in a second direction.

12. The method of claim 9 , comprising:
the first light is configured to function as at least one of a daytime running light or a position light;
wherein the status of the one or more batteries of the vehicle is a charge status of the one or more batteries of the vehicle.

13. The method of claim 9 , comprising:
the divider configured to at least partially block light between a first segment of the plurality of segments and a second segment of the plurality of segments.

14. The method of claim 9 , comprising:
the first transparent portion and the second transparent portion of the cover interlocking with the opaque portion of the cover.

15. A vehicle, comprising:
a lighting apparatus, comprising:
a first light bar configured to display a first light from a first source to a first light guide, the first light guide configured to reflect the first light in a first direction from the first source, the first source coupled with a first printed circuit board; and
a second light bar comprising:
a divider configured to define a plurality of segments of the second light bar; and
a second light guide configured to reflect a second light in a second direction from at least one second source to the plurality of segments, the at least one second source coupled with a second printed circuit board;
a cover at least partially surrounding the divider and the second light guide, the cover having a first transparent portion, a second transparent portion, and an opaque portion coupled with and disposed between the first transparent portion and the second transparent portion to provide a patterned display of the second light;
the divider extends along the second light guide outward beyond an end surface of the second light guide in the second direction towards the cover;
the second printed circuit board disposed between the first light guide and the second light guide; and
the second printed circuit board configured to:
 control the at least one second source to emit the second light via the plurality of segments to produce a linear display to indicate a status of one or more batteries of the vehicle.
