I make a point of checking at least once a week - I have to get out of my car when leaving the house to close a set of gates, so I grab a big rock from the yard to wedge down the brake pedal and walk around the vehicle doing a brief inspection.
It's annoying at first, but quickly becomes habit.
My 2000 Audi has an indicator light that comes on if one of the stop lamps is not working.
It would be nice if this was a standard feature in every car. Trying to determine whether the lights in the tail lamp cluster are all working without some assistance is difficult at best.
