1. An adjustable light beam device for an aimable vehicle lamp assembly, comprising:
- a lamp housing having a channel member with an outer portion and an inner portion, the inner portion of the channel member having at least one slot formed therein;
a light source disposed within the lamp housing;
a tube component positioned within and movable along the inner portion of the channel member such that the light source projects light through the tube and the position of the tube is adjustable in relation to the light source, the tube comprising a first end located proximate the light source and second end located distal from the light source;
a wall extending across an interior portion of the tube component and having an aperture formed therein such that the light source projects light through the aperture, the wall being positioned spaced apart from the second end of the tube component such that a portion of the tube component extends between the wall and the second end; and
at least one resilient snap member formed on the tube component, the resilient snap member being positioned within the at least one slot of the channel member.

14. A method of adjusting a light beam diameter in a vehicle lamp assembly, comprising the steps of:
-
positioning a channel member, with an outer portion and an inner portion, of a lamp housing proximate to a light source capable of emitting a beam of light; positioning a tube component within the inner portion of the channel member such that the tube component is able to be adjustably moved along the inner portion of the channel member, the tube component having a first end positioned proximate the light source and a second end positioned distal from the light source; providing a wall within the interior portion of the tube component, having an aperture formed therein such that the light source projects the beam of light through the aperture; positioning the wall spaced apart from the second end of the tube component such that a portion of the tube component extends between the wall and the second end; positioning a plurality of resilient snap members of the tube component into corresponding slots formed in the inner portion of the channel member; slidably moving the resilient snap members along the corresponding slots; and varying a diameter of the beam of light as the tube component is moved along the inner portion of the channel. - View Dependent Claims (15, 16, 17)
