Serious LED/DRL issue
I have an issue with my current setup. I have some white/white 3157 led's for my drl's and they have resistors in line parallel. The issue is when my turn signal stalk is set to auto, the driver side goes to the brighter drl filament as usual, but the pass. side shuts off completely. This usually happens after a few minutes of driving. I don't know exactly how long, but usually my trips are less than 30 mins. I will notice my right drl will be off. Also, the driver side will erratically shut off on it's own and flicker on and off sporadically when set to auto. Strangely, they work correctly with my lights on where they are dim except after two or three times signaling right, the brighter filament will quit flashing on just the pass. side with the left signal working with repeated attempts. If I shut off my car and turn the lights on again, same thing happens. Pass. side works three times, then stops just sitting there dim. All tail lamps are working too.
Have you ever heard of this happening? Any advice on how to fix this would be greatly appreciated.

So, I contacted the LED experts at Autolumination and was informed that the resistors have no effect on the running lamps and if they're going out, resistors may need to be added to the running lamps circuit.
Anyone ever experienced this or know if dual resistors would remedy my situation?

ran into this on a different vehicle, not a vette. the disputer looked at resistance of the circuit, including the bulb. when you changed bulbs, it changed system resistance in all likelyhood. remove a bulb and check old vs new to find out. it may be corrected by bringing the resistance of the circuit back to near factory specs by adding anudder resistor. would think this holds true in your case, but cannot guarantee that. there are probably some really smart car guys who will come along and add to this.

I assume you have one resistor on each side. What is the value of the resistor? The 3157's will work differently if you have them plugged in "backwards". There are 2 circuits in each LED. Try turning one around in the socket. Which 2 wires (colors) do you have the resistor across?

That is the dumbest thing I've ever heard.
I'm considering disconnecting the resistors and just going hyper. I really want them to work though.

The wiring is right, could be the wire tap. The best thing to do is to solder the connection. The problem when not using the resistors is if you have the lane change feature the flash is too fast to be effective. If that is not a consideration don't use the resistors. It would also be better to change the tail lights. With the filaments in the standard bulbs they don't get the chance to turn off between flashes which may be an issue. Check it out.
