IDK how the SuperbrightLEDs are regulated. They may be the same. You gotta investigate; if you have one cut it open and take a look... or find someone who did that. Internet is a thing.

The resistor is in series, I don't think it can increase the LED's current draw. But I suspect that resistor is the weak link in the cheapo LEDs. The ones that have died on me had both dead LEDs and dead resistors. I suspect the resistor shorted out and then the LED burnt out on the full 12v.
I have a 194 from SBL in front of me right now. Two resistors and a pair of semiconductors that I can't make out through the case. But I know they're acting as a bridge rectifier, the bulb is not polarity-sensitive.
