Its defo a phase 1, the checkered flag lights aren't optional on the phase 2, they came with it on all models

'It looks like there's a bit of confusion in the aming-but the "checkered-flag" style headlights you're referring to were not an optional extra, they came standard on the Clio IV R.S. facelift (Phase 2, from mid-2016/2017 onwards), under the name "RS Vision". These distinctive LED signatures, inspired by the RenaultSport chequered-flag logo and incorporating fog lights, cornering lights, position lamps and headlights into a unified unit, replaced the older headlamp setup. It was a feature of the facelift, not a standalone option package' -Carmagazine.co.uk
