Mike_is Posted April 25, 2007 Report Share Posted April 25, 2007 Okay, So I'm building an indicator system for a designing class in secondary school. The problem is that I can get a normal Car headlight flashing using a 12v Battery, Thermal Flasher and light bulb BUT when i replace the light bulb with a 12v LED light, the circuit doesn't seem to work.Anyhelp with be appreciated, thank you.

ante Posted April 25, 2007 Report Share Posted April 25, 2007 Hi Mike,This thermal flasher depends on a higher current to be drawn than the LED will draw to work properly. Try by paralleling the LED with a normal bulb and they both will flash.If you need the circuit to work with only the load from a LED you have to build an electronic circuit instead.Look up (Google) Quote Link to comment Share on other sites More sharing options...
Mike_is Posted April 28, 2007 Author Report Share Posted April 28, 2007 Thank you for the help.I know i might asking for abit too much, stop me if I do, but after having a look at a few sites on how to build a circuit board, I was wondering if you can give me a run down on it.I have very very little/basic knowledge with circuits and building one with my knowledge is just like hammering a nail without a hammer.

ante Posted April 28, 2007 Report Share Posted April 28, 2007 Well, hammering a nail without a hammer might cause injures to your hand! :o I suggest you try strip-board for small projects like this.A good place to start is where they make a circuit just like the one you need and conveniently enough on a strip board! ;DHere it is good luck!http://www.kpsec.freeuk.com/stripbd.htm Quote Link to comment Share on other sites More sharing options...
