I've had the superbrightleds.com LEDs installed for about a week now and there are no side effects that I am aware of. There are no error messages on the cluster, no hyper flashing, and no dimly lit bulbs like the Philips and other brand of T10 LEDs. BTW, in my quest for the perfect LED bulb, I also tried a set of
AGT (Advanced German Technology) T10s which turned out to be no better than the eBay variety but at a premium price. I do not have a DICE so I do not know if the ECM stores an error code but I highly doubt that it does. I remember having the ignition on while I removed one of the license plate lamps and no error codes were thrown. You can try it yourself prior to ordering the LEDs. Have fun!
