Spinifex I agree with your sentiments re lights on however I feel that DRL do a better job than lights on, DRL are designed to be seen, i.e. they are not pointed down light low beam. I've enabled the Scandinavian DRL in my car via OBD Eleven so I have the rear lights on too. The only downside to this mod is you never know when the auto headlights are on as the indicator always shows them on.

Cheers,
