How to create a LED on your own

LED for cars is marketed,But I’m poor, so I makes by oneself.

Prepare the first necessary things “Soldering iron” and “LED 15mA-20mA” and “Electrical cord red black” and “9 volt battery for tests” and “CRD 15mA-20mA (Constant current diode 15mA-20mA)”


  1. ”CRD+” is connected to red cable
  2. ”CRD-” is connected to “LED+”
  3. “LED+” is connected to “Black cable”


Finally test 9 volt battery


Is no problem until the “1 of CRD” with respect to the “3 of LED”
