Excellent bulb output, notches and alignment matches once you get the hang of the installation method.
Lights fit properly light up nice and bright. Order was sent in a good timely fashion.
I upgraded my low beam, high beam and fog light (Amber) on my 2004 Land Cruise and 2018 WRX with A1 Ultra. Loving it, way brighter than stock. The only thing is that my Land Cruiser lost its DRL which was expected. So for older cars with DRL, check first before upgrading to LEDs due to the voltage LED requires.
Easy installation, perfect fit much brighter than original halogen bulbs. Nice to be more visible.
The lights work great but there is no way to lock the lights as either white or yellow.
