I’m maybe mixing up those with auto lights. As I always have them in auto unless I feel lights are needed and have not come on
Again, this is where confusion reigns. When car lights are left on ‘auto’ (as they should), in normal daylight driving conditions the front DRLs are illuminated but there is no illumination whatsoever at the rear. It is only when the sensors determine that headlights are needed that the rear lights illuminate. Some auto headlight sensors don’t react early enough, especially in poor weather conditions, but because the dashboard is always illuminated these days (not just when headlights are on – as used to be the case in the past) drivers have no idea that they have no illumination at the rear and are putting themselves in danger as a result. I am just staggered that this system ever passed safety sign off.
