Hi all.
I'm trying to figure a way to limit the current to some LED side repeaters/markers on a bmw.
They work perfectly untill you turn the ignition off and they remain lit, albeit super dim.. i have a feeling that it is to do with BMW sending some kind of 'retentive' power to all bulbs, which is used to determine if you have a bulb blown, and thereby signify this on the dash.
The easist way is to solder a resistor into the positive side of the circuit, just before the bulb.
Pay a visit to your local Maplin Electronics store and spend just a few pennies.
