Review on Upgrade Your Headlights With H1 LED Bulbs: 8 Sides CSP Chips, Super Bright White 6000K And 12000LM For High/Low Beam And Fog Lights - Get 360 Degree Lighting by Robert Ogrodnik

2011 ford edge upgrade. No instructions but you have to adjust the bulb sliding them front to back direction once locked into the socket and headlights on. This is to focus the LED to find the sweet spot in the projection lens. You must adjust the bulb as they are very dim and then suddenly are bright once focused. I found doing this at night and pointing them at the garage door was helpful. I also had to adjust my headlight assembly to maximize the High Beam mode. I like the light color and brightness of the new bulbs over the stock Halogen I replaced. These are the first LED lights i have purchased so I cannot compare them to other brands.
