A lighted safety ladder includes two rails and a plurality of rib members connected to the two rails. A platform may be provided at one end of the ladder and is located above an uppermost one of the plurality of ribs. A light source is provided on one or both of the rails; one or more of the plurality of rib members; and one the platform. The light source may be in the form of a light emitting diode (LED) strip that is installed in a slot defined in the rails, the rib members or the platform or that is adhered or otherwise secured to the surface of the rail, rib member or platform. The light source provides illumination to the rails, rib members and/or platform so that an operator may better see these components in low lighting conditions.
