Someone has yanked my alarm LED from my motorcycle.
I called the alarm manufacturer and they told me that alarm system is discontinued but that I could go to Radio Shack and buy any red LED at 12V with less than 5 mA draw. The smallest drawing LED I could find with that voltage was a 15 mA and so I picked that one up and installed it on my motorcycle: Great bright red light, more than I really needed but I figured it's an alarm LED, the brighter the better but sure enough the first time I did not use my motorcycle for 3 days in a row, I found the battery almost dead.
What should I do to reduce the current drawing to <5 mA...? I am willing to loose a lil brightness, someone told me 1K resistor in series, someone told me a few diodes in series.... I am confused....
