## Abstract

A portable light source for connection to a hardhat. The portable light source has a battery housing with an LED light mounted in a lamp holder that is connected either directly to or via a boom or wires to the battery housing. The housing or the lamp holder also has a mounting post that engages an aperture on the side of the hardhat for holding the portable light source in place. The lamp housing may be rotatably connected to the battery housing.

### Claim 4 (depends on 3)

The portable light source of claim 3, further comprising a pivot joint between the lamp housing and the mounting post, wherein the pivot joint is configured so that the lamp holder is rotatable relative to the mounting post.

### Claim 5 (depends on 4)

The portable light source of claim 4, wherein the pivot joint is configured so that the lamp holder is rotatable relative to the mounting post to any position within a 360° arc.

### Claim 6

A portable light source for mounting on a hardhat having a side aperture, the portable light source comprising:
a) a housing holding a battery;
b) a lamp holder, for supporting a lamp;
c) a connecting member connecting the lamp holder to the housing;
d) electrical wires for connecting the battery to the lamp; and
e) a mounting post fixed to the lamp holder and having a resilient clip fastener,
wherein the mounting post is configured and dimensioned to fit into the side aperture of the hardhat, and the clip fastener engages the side aperture to secure the portable light source to the hardhat, and
wherein the housing is separately supported by the connecting member.

### Claim 7 (depends on 6)

The portable light source of claim 6, further comprising a pivot joint between the lamp housing and the mounting post, wherein the pivot joint is configured so that the lamp holder is rotatable relative to the mounting post.

### Claim 8 (depends on 7)
