Laterally supported lights

1. A light configured to be mountable on a hanger of a modular lighting system that includes two parallel rods that are covered with a protective layer, the light comprising:

a body having at least one surface supporting a light source; and

a first wing and a second wing that extend directly from the body, the first wing including a first cavity that extends along a first axis and at least one first projection that extends transverse to the first axis and into the first cavity and the second wing including a second cavity that extends along a second axis that is different from the first axis and at least one second projection that extends transverse to the second axis and into the second cavity, the first cavity and the second cavity each sized and shaped for selective attachment to a respective one of the rods such that when one of the rods is arranged in the first cavity of the first wing, the at least one first projection is configured to at least one of pierce and cut the protective layer of material of the one of the rods so as to make electrical contact with a conduit in the one of the rods and when the other one of the rods is arranged in the second cavity of the second wing, the at least one second projection is configured to at least one of pierce and cut the protective layer of material of the other one of the rods so as to make electrical contact with a conduit in the other one of the rods.

2. The light of claim 1 , wherein said light source is powered by current passing through the rods.

3. The light of claim 1 , wherein said first wing and said second wing are configured to provide an electrical connection between said light source and said rods.

4. The light source of claim 1 , further comprising a cover made of light transmissive material extending over said light source.

5. The light of claim 1 , wherein said body has two opposed surfaces and each of said surfaces includes a light source disposed thereon.

6. The light of claim 1 , wherein said wing and said second wing are shaped and configured to form interference fits with the rods.

7. The light of claim 6 , wherein the at least one first projection and the at least one second projection are knives.

8. The light source of claim 1 , wherein the first wing includes at least one cutout extending transverse to the first axis and the second wing includes at least one cutout extending transverse to the second axis, and the at least one first projection is arranged in the at least one cutout of the first wing and the at least one second projection is arranged in the at least one cutout of the second wing.

9. The light source of claim 1 , wherein the first wing includes a plurality of projections and a plurality of cutouts extending transverse to the first axis in which the plurality of projections are arranged and second wing includes a plurality of projections and a plurality of cutouts extending transverse to the second axis in which the plurality of projections are arranged.

10. The light source of claim 1 , wherein the first cavity of the first wing includes a first detent extending from an inner surface thereof and the second cavity of the second wing includes a second detent extending from an inner surface thereof.

11. The light source of claim 1 , wherein the body, the first wing and the second wing are a single, one-piece element.

12. A light configured to be selectively mountable on a first rod and a second rod, which each includes a rod core covered by a layer of insulation, of a modular lighting system, said light comprising:

a body having at least one surface with a light source disposed thereon;

a cover disposed over said light source, said cover being made of a light transmissive material to allow light from the light source to project through the cover; and

a first wing and a second wing attached to and extending directly from said body such that the body, the first wing and the second wing are a one-piece element, the first wing includes a first cavity that extends along a first axis and at least one first projection that extends transverse to the first axis and into the first cavity and the second wing includes a second cavity that extends along a second axis that is different from the first axis and at least one second projection that extends transverse to the second axis and into the second cavity with each of said first wing and said second wing configured to selectively engage one of said rods to support said body on said rods, said first wing and said second wing further being adapted to pierce the layer of insulation on the rods when said rods contact said first projection and second projection and provide electrical connection from the rod cores to the light source.

13. The light source of claim 12 , wherein the at least one first projection is a first knife and the at least one second projection is a second knife.

14. The light source of claim 12 , wherein said body includes two surfaces and light sources disposed on said surfaces.

15. The light source of claim 12 , wherein the rods extend vertically in parallel to each other and the body is attached at any point along a length of the rods.

16. The light source of claim 12 , wherein the first wing includes at least one cutout extending transverse to the first axis and the second wing includes at least one cutout extending transverse to the second axis, and the at least one first projection is arranged in the at least one cutout of the first wing and the at least one second projection is arranged in the at least one cutout of the second wing.

17. The light source of claim 12 , wherein the first wing includes a plurality of projections and a plurality of cutouts extending transverse to the first axis in which the plurality of projections are arranged and second wing includes a plurality of projections and a plurality of cutouts extending transverse to the second axis in which the plurality of projections are arranged.

18. The light source of claim 12 , wherein the first cavity of the first wing includes a first detent extending from an inner surface thereof and the second cavity of the second wing includes a second detent extending from an inner surface thereof.
