reduce led current draw
yes... I ended up putting a amp meter in series as I was trying different resistors and a 3k3 value brought it down to <5 mA. It was sorta difficult to read the exact value since the alarm makes the LED intermittent, so I only had a fraction of a second to read the meter and everytime the LED...- Telomostro

reduce led current draw
The LED I got from RS was a 12V rated one and I think it has a built in resistor but, if I understand correctly, you say that adding another resistor in series (i will experiment with the different values you sugested) will indeed drop the current that it draws from the battery... right...- Telomostro

reduce led current draw
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...- Telomostro
