Yes, I have them and I hate them. Couldn't see anything in the fog around Pebble Beach. I especially dislike the ones that look like LEDs. They all take a scatter-shot approach to lighting. Most just blind oncoming traffic and get you the driver's salute.
Stock headlights are OK, if you make sure they are properly grounded and that they are getting full voltage. There are a number of connections that could dim the headlights, including the headlamp switch. It's prudent to do a voltage check every step of the way to make sure the headlights are getting full-voltage. I spent 40 years in the lighting business and low voltage is the bane of all lighting.
