How can i hook up several emergency lights in my car? - emergency car lights

Often people who help to fall on the side of the road and wants to yellow lights in my car to me safely. I plan to put a front and 2 rear. The problem is that I avoid just 2 points on the sale of cigarettes and would prefer a reform of the entire electricity generation. What can I do to connect all three years combined, there will not cost a fortune.
