Abstract: A dome light and stabilizer fin accessory kit is provided for use with toy flying discs. A socket is attached to the top center portion of the flying disc and a plug is inserted therein. The plug contains either the dome light with battery or a stabilizer fin assembly. The stabilizer fin rotates about a pin connected through an aperture in the plug. The leading edge of the fin includes a counter-balance such as a weight or battery-powered lamp. The trailing end may include an adjustable rudder.
