Diode Dynamics needs to invest in quality control. The worst LED headlights period. Manufacturing can't be this bad, but it is! I'm on my 4th bulb in 2 months. Diode Dynamics says the issue is with a power surge. If it's a power surge, then why does the right bulb go out, then a week later, the left bulb...? Hard to believe since different bulbs burn out, the truck battery is $600 to prevent power surges since everything is electronic in the vehicle, run by a computer. I had the same horrible QC issue with a truck 5 years ago, bulbs would last less than 30 days. Buy other headlights and save yourself the hassle of calling to get a POS replacement bulb.
