Flashing or intermittent lighting shall only be permitted in the C-4 and C-5 zoning districts, and shall remain within the restrictions of section 15.04.130 of this title, and no rotating or any form of moving sign shall be permitted; provided, however, that a time-temperature sign may be permitted by the approval of the city council in the C-3, C-4 and C-5 zoning districts when it will be operated as a part of a permitted sign by a business occupying a structure on the premises.
