They need a better design for sure. The OEM bulb is so easy to install but the LUX are a pain in the butt. It took me forever to do mine when I first got them. Then one of my LUX power supplies failed 2 months out of warranty and I had to get it repaired and fight to get it in all over again. Just take your time on it and I am sure you will get there eventually
BTW: My car had less than 9000 miles on it when one of the LUX failed 14 months later. I hope others have better luck than I did.
