I've had a high fail rate with these bulbs, in 2 different cars. reason is they string the LEDs in series to get the 2.2volt required. This is why you see burnt sections on LED taillights every so often. When voltage is first applied, the full 14 volts hits the first LED for a microsecond, which kills it quickly. I'm making my own using a 680 ohm resistor for each high-brightness LED and mounting them in a drilled backing plate. Each LED-resistor section is then wired parallel to each other. No failures yet!
Best of luck!
