So recently, i got to build this simple blinking led circuit using 555 timer from instructable: http://www.instructables.com/id/Flashing-LED-using-555-Timer/.
Now, for a project i'm doing, I need to build a similar thing but the light source has to be clearly visible from a distance (~30m). I'm thinking of using truck taillight as a light source (one of these maybe: http://www.princessauto.com/pal/en/Tail-Lights/4-in-LED-Stop-Turn-Tail-Light/8126047.p)
Since it's no longer a single LED circuit, I don't know the intructables circuit would work anymore (dont really want to waste $29 to test it out). I would like to have some experts' ideas about it and someone to help me with these concerns:
1) is it possible to power 12v LEDs truck light using 9v batteries? if so, how long would it last ?
2) Is there an alternative way to build this blinking circuit without using 555 timer?
I appreciate any advices/comments or circuit layouts ...
Thank you! (Sorry for my bad English)
