Cheap Faux Alarm Blinking Red Light
Posted: Tue Feb 07, 2006 7:53 am
I've installed this in many cars, red blinking light (security) that comes on when key is off and goes off when key is on, looks like a security light. Mount the LED where it can easily be seen from the outside of car, from the driver's side window.
B+ ---------> 470 ohm ----------> blinking red LED ----------> B+
constant_____.5 watt resistor_____RS #276-036, 5mm________w/KOEO
B+ constant: constant power = brakelights.
B+ w/KOEO: power when key on engine on.
You can by a 5 pack of the 5mm holders to mount the led on the dash, goes between the bulb and dash. Looks very realistic, cheap mod, < $5 total. Use a 1/4 inch drillbit to drill hole.
