I noticed something today when converting my sidemarker bulbs to LEDs from www.superbrightleds.com. I think when the lights are off, and the turn signal is on, the current flows in one direction through the sidemarkers when the flash on, and when the lights are on, it flows in the other direction. anyone ever put a meter on them? since normal filament bulbs work just fine with current in either direction, so they work fine whether the lights are on or off, but with LEDs, they are diodes, and only illuminate when current flows in a certain direction. hense the reason that they only work properly when the lights are on, and not when off. I don't really care since I never drive my car without the running lights on, no matter what time of day it is. but just an FYI for anyone wanting to do this, you'll have to change them back for your inspections!

Are these the 194's we're talking about here? If they are, try turning them around if you havent already. Some brands of LEDs require you to turn them around if they dont work one way. I have LEDs in my rear taillights and turn signals and never had a problem like that.
well if I turn them around the don't work when I have my normal lights on. they are in there the right direction, then work just fine, flash just fine as long as the lights are on, but they don't flash if the turn signals are on when the lights are off. it kinda makes sense, you notice that when you use the turn signals with the lights off, they flash all together, but if the lights are on, the side markers flash in an alternating pattern with the front lights. its just the sidemarkers that are wired this way, the front and rear turn signals function normally whether the lights are on or off.
btw, which lights do you have in your main turn signals? do you like them? brighter or dimmer then the conventional bulbs? I'm thinking about doing them too, just haven't gotten around to it.

all LEDs work that way, LED stands for Light Emitting Diode, a Diode is a device that allows current to flow in one direction, but not the other. hense all LEDs are directional or polarized. they will only work in one direction. its just the way LEDs are.
