## CS ADR-DSN.M.740 De-icing/anti-icing facility exit lights

(a) Applicability: The purpose of the [de-icing/anti-icing facility](https://avioverse.aero/glossary/easa/de-icinganti-icing-facility) exit lights is to indicate the exit boundary of a remote de-icing/anti-icing facility adjoining a [taxiway](https://avioverse.aero/glossary/easa/taxiway).

(b) Location: Where provided, de-icing/anti-icing facility exit lights should be located 0.3 m inward of the [intermediate holding position](https://avioverse.aero/glossary/easa/intermediate-holding-position) [marking](https://avioverse.aero/glossary/easa/marking) displayed at the exit boundary of a remote de-icing/ anti-icing facility.

(c) Characteristics: Where provided, de-icing/anti-icing facility exit lights should consist of in-pavement fixed unidirectional lights spaced at intervals of 6 m showing yellow in the direction of the approach to the exit boundary with a light distribution similar to taxiway centre line lights (see Figure M-11).

(d) De-icing/anti-icing facility exit lights chromaticity should be in accordance with the specifications in CS ADR-DSN.U.930 and Figure U-1A or U-1B, as appropriate.
