I installed them in my 2014 Ford Focus - a very easy task since you can remove the complete headlight unit after removing 2 screws (you'll need a T30 torx bit). Then I tested them using my lux meter. I parked the car 8 feet from my closed garage door and looked for the brightest spot. The halogen light was 700 Lux, the Sealight LED headlight was 1300 Lux, about 2 times brighter. Subjectively the LED lights were brighter, too, when I drove around at night, with a good light pattern. No rating on See full review
