Hi all
I notice recently that a lot of cars are coming with daytime lights.
A massive improvement on the idiots that won't turn on lights unless it is pitch black.
My problems.
The rear lights don't light up at the same time.
In my opinion in the recent bad weather headlights should be on for visibility DRL's don't cut it.
Does having your dimmed lights on affect the battery in any way while driving.

Well, obviously the power required to keep the lights on does not come from nowhere and does not come free. But with modern alternators, there is none to minimal impact on the battery unless you also have the demisters,heater fan/s, wipers, heated seats etc. all on and are in a traffic jam for ages.
Even then if all is working properly no impact will/should be noticeable, same goes for fuel consumption which is fundamentally where the power comes from in the first place.

Yes, but your driving style will have a much greater impact on consumption.Low power LED DLR lights have negligible effect, but even then, with a small petrol engine, DLR can result in a 1.6% increase in fuel consumption. That's to run the 2x5 to 10W LED forward facing lights only.
If you then move to 2x55W dipped headlights, plus the side lights and rear lights (up to 160W), the effect on fuel efficiency is obviously going to be greater.
