Thanks for that link RichardV6. Reading those posts it seems my 2018 Roadster comes with both front & rear sidelights coming on with the ignition (unlike my Plus 4 GDi). I fitted these headlamps to the Plus 4, but that didn't have the 'always on' sidelights, so I may need to rethink how I do this. I wanted to know if by introducing the DRL module into the electrics it would cause problems with the CAN system.
