I got these to install into my wife's little Acura Integra to replace the dull normal headlights now that it is getting darker sooner in the evening and neither of us could be happier with them. They throw out a brillant beam of bright white light that cuts through the foggiest and darkest of night and illuminate the road perfectly. Install was easy and straight forward, just connect them to the stock bulb connectors and they lock into the headlamp housing just like the original bulbs. I had these installed in about 15 minutes and that is including removing the car battery for access to the headlamp (thanks Acura for the poor design!). They have no flicker, the fans on the base make no noise, and so far after 2 moths of daily use are still working perfectly. Since her car only uses 1 bulb for both High and Low beam, these handle the job with no issues at all. I liked them so much I bought 2 other sets to install in my car and had the same great experience with those as well. Fantastic lights that make a huge difference over the normal bulbs!
