Extra light bulb in the head light assembly

They lose even more of their purpose if you have DRLs.

well im not a fan or DRLs, i see no purpose for them ?

if its bright in the day, you dont need lights... if its getting dim, you should still be able to see perfectly or you need to get your eyes checked... but thats what the "parking lights" are for, dimness.
and when its dark... lights.. plain simple

Day time running lights are required in Canada to make vehicles more visable coming out of tunnels and shaded areas. Some states require head lights on when using rain wipers.

Both of my Yarises have those DTR lights which use the main head light bulbs (low beam?). As some truckers have on the back of their trailers, LIGHTS ON FOR SAFETY. I am wondering if these running lights are bright enough to use if the low beam filiment burns out. But it sounds like the running lights are not powerful enough to be legal to use as low beams.

That is completely understandable and common practice... for the most part with smart drivers. We have many threads on drivers not doing it -.-. When weather obstructs, lights should be on to increase visibility.

Well I can think of one way to put the running lights to use. If the low beams burn out, the running lights combined with fog lights should be safe enough to get home. High beams might be needed if driving on a Interstate or other high speed road.
