How are the ones that look like a circuit board going for you? I bought the WLEDx6 bulbs from superbrightleds and 1 after the other bit the dust. I called them and they said they can't do anything about it since it was over a year. The 2 license plate and 3 dome either flicker or don't work at all.

 

got mine at superbrightleds.com great product, Customer service and shipping!
