Radio switching on/off with full beams, lights flickering full steering wheel turn

2015 Vauxhall Astra SRi auto
Car: Vauxhall Astra
Year: 2015
Variant: SRi auto
Categories: Electrics, ECU, Warnings & Lights
So my 2015 SRi auto now switches radio/central panel on and off when turning on full beams and sometimes when turning on rear window demister. Sometimes just when driving away when doors lock, radio switches off and on. Now when turning the wheel fully, the main lights will flicker. What could this be? Worried my car is just going to cut out completely or headlights might switch off completely. Any thoughts appreciated

You will need to get your battery LOAD tested and alternator voltage also . They cannot cope when the demister , headlights are switched on
