As a Noun: 1. The lights in the dashboard of a vehicle which illuminate the gauges and accessories. English = dash lights. Note: 1. There appears to be no commonly used Auslan sign for DASH LIGHTS for most signers (but some signers represent this visually using these depicting signs, once they have established the topic). This suggested sign is a compound of IGNITION and LIGHT. Source of this recommended sign: Victorian College for the Deaf.
