Light source

I would like to enquiry which light source is suitable for my project as i am doing smart traffic. i used ca light bulbs and normal tourch bbs but they draw too much current. Anyone can advice me wat suitable bulbs o use?
 

Re: Light source

Maybe another popular choice is LEDs, which is light and more power efficient than most car bulbs. They have been used widely in many luxury cars.
