1. A light emitting unit, comprising:
an annular form factor sized to circumferentially surround a user's head when the light emitting unit is worn by the user, and including a rigid housing and an attachment mechanism that is distinct from and coupled to the rigid housing; and
a plurality of lighting elements supported within the rigid housing at least in a rear portion of the light emitting unit and arranged to generate a partial halo of light behind the user's head when the light emitting unit is worn and the plurality of lighting elements are illuminated,
wherein the attachment mechanism comprises a flexible band structure that is configured to be stretched or elongated to receive a portion of a hardhat or other headgear of the user and to thereafter apply a bias or inwardly directed pressure to the hardhat or other headgear to retain the light emitting unit in position on the hardhat or other headgear, and so as to enable the user to selectively attach and detach the light emitting unit to the hardhat or other headgear of the user without compromising the integrity of the hardhat or other headgear.
