A light system that attaches to a helmet. The light is designed to be removable. The system has a forward head light that enables a rider to illuminate in whatever direction the rider's head is looking. It has a translucent shell. In one embodiment, the shell is colored red. Light from the headlamp is allowed to leak through the rear of the shell, which gives the appearance of a taillight. In a second embodiment, the device has a forward headlamp and a second bulb that illuminates the rear shell. In a modification of this embodiment, the rear lamp has two filaments. One filament remains on all the time and acts as a taillight. The other filament is activated by the brake handle of the vehicle. In this way, it acts as a brake light, further warning other riders that the vehicle is slowing.

1. Field of the invention
This invention relates to lights that are attached to helmets and particularly to lights that are attached to helmets that have both a headlamp and a tail lamp.
FIG. 1 is a perspective view of the invention.
FIG. 2 is a cross-sectional side view of a second embodiment of the invention.
FIG. 3 is a side view of the invention.
Referring now to FIG. 1, the helmet light 1 is shown. The light 1 has a plastic shell 2. In the preferred embodiment, the plastic shell 2 is translucent. In the preferred embodiment, shell may be colored. The preferred color is red; however other colors, such as yellow or amber may be used. A headlamp 3 is mounted inside the shell 2 as shown in FIG. 2. In the preferred embodiment, the headlamp 3 is a 35-watt halogen type bulb. Such as a MR-16 type with a G 5.3 connector base. This type of bulb has a filament 4 and a reflector 5 in one formed unit. See FIG. 1. It is also possible to make the device using a small bulb 4a and a reflector 5a, see FIG. 2. In either case, the housing 2 is designed to hold the headlamp in place. Note that the electrical connectors and the housing are designed to withstand the heat generated by the head lamp bulb.
In one embodiment of the device, the light produced by the headlamp 3 illuminates the entire shell. White light projects forward to illuminate in front of the user. Because the shell is red plastic, the light emanating from the back of the shell, however, appears red, like a taillight.
In the preferred embodiment, a second bulb 6 is placed in the shell as shown. This bulb can either have one or two filaments. In the case of one filament, the bulb 6 is activated by a momentary contact switch that is tied to the operation of a vehicle's brakes. Thus, when a rider activates the brakes, the second light illuminates the back of the shell. This bulb then acts like a brake light.
