What are the possible reasons why cars behind you turn their light on even in day time?

Sometimes I drive not very fast even if there is no traffic. i'm a novice driver.

It is proven to reduce the number of head on collisions. In Canada turning your lights on whenever the car is running is mandatory and the cars sold there are wired so that the "daytime running lights" which are usually your headlights come on automatically when you start the car.

The same wiring is also in all US cars but the relay for this has not been installed.

When I moved to Canada in 2010 from LA, I had to install the relay into the car's relay box,

I run on lights most of the time. It makes the car much more visible to oncoming traffic. Newer car are now coming with Day running lights for this reason.

It makes cars more visible.It's a legal requirement that new cars display lights at all times.

Some cars have their lights on all the time. Even though it may be daytime for some people it still makes your car more visible.

some cars automatically have them on all the time

some people just want to be seen better
