In some embodiments, a cap covers the center hole of the wheel after the wheel has been installed on the stroller. In some embodiments, the light components are light emitting diodes (LED). In some embodiments, the light components are positioned near the center hole of the wheel. In some embodiments, the wheel is transparent or translucent, wherein light components are disposed in the wheel. In some embodiments, the battery is disposed in the center hole of the wheel. In some embodiments, the battery is a solar powered battery.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIG. 1-5, the present invention features a stroller wheel 100 comprising a light system for illuminating the wheel. The light system in the stroller wheel 100 can help make a stroller 101 more visible to drivers and pedestrians.
The stroller wheel 100 of the present invention comprises a wheel 110. The wheel 110 may be similar in shape, size, and composition to standard stroller wheels, which are well known to one of ordinary skill in the art. For example, in some embodiments, the wheel 110 is constructed from a material comprising a rubber, a plastic, a metal, the like, or a combination thereof.
The wheel 110 has an outer surface and a center hole 115. In some embodiments, a wheel 110 is attachable to a stroller 101 by sliding the center hole 115 onto an axle of the stroller. One or more caps 130 may cover the center hole 115 once the wheel 110 has been installed on the stroller 101.
Embedded in the wheel 110 are one or more light components 120. The light components 120 may be light emitting diodes (LED) or other type of illuminating means. In some embodiments, the light components 120 are positioned all along the outer surface (e.g., circumference) of the wheel 110. In some embodiments, the light components 120 are positioned in other locations on the wheel 110, for example near the center hole. In some embodiments, the light components 120 are disposed in the wheel 110 and the wheel 110 is transparent/translucent.
The light components 120 are operatively connected to a power source via one or more wires 150. In some embodiments, the power source is a battery 160. The power source (e.g., battery 160) may be disposed in the wheel 110 or on the wheel 110, for example in the center hole 115 of the wheel 110 (see FIG. 2). In some embodiments, the power source is solar power. For example, the light components 120 are operatively connected to one or more solar cells 510 (see FIG. 5). Solar cells are well known to one of ordinary skill in the art.
The stroller wheel 100 further comprises a control switch 210 for turning on and off the light components 120. The control switch 120 can move between an on position and an off position. In some embodiments, the control switch 210 works via force (e.g., centrifugal force). For example, as the wheel 110 is spun, the switch is forced to the on position. This allows power to be directed from the power source to the light component 120. When the wheel is not spun, the switch returns to the off position, preventing power being directed to the light components 120. Such switches are well known to one of ordinary skill in the art.
In some embodiments, one or more stroller wheels 100 of the present invention may be installed on a stroller 101. For example, two stroller wheels 100 may be attached to the front of the stroller 101, or four stroller wheels 100 may be attached to the front and back of the stroller 101.
Without wishing to limit the present invention to any theory or mechanism, it is believed that the stroller wheels 100 of the present invention are advantageous because the light components 120 are built into the wheel (e.g., rubber of the wheel) and the light components 120 are activated as the stroller is in motion and deactivated when the stroller is stopped. The wheel design helps ensure that others see the stroller, since the lights will be on during movement. The lights of the present invention will attract attention much more readily than other light systems in stroller wheel hubs, therefore ensuring the safety of those in and around the stroller. As the stroller is guided forward, backwards or turns left or right, the lights will be visible. The occupant of the stroller will be safe as visibility is greatly enhanced for drivers or those walking in a dimly lit area.
