Ghost Light

You touch one object that is no larger than 10 feet in any dimension and specify any number of creatures you can see within 10 feet. Until the spell ends, the object sheds silvery Bright Light in a 20-foot radius and Dim Light for an additional 20 feet. This light is only visible to the creatures you specified during the casting of the spell; all other creatures perceive the area affected by the light as they regularly would.
