My last H11 bulbs were Sylvania ZXE and they were bright but still yellowish. I wanted white low beam headlights without a tinge of yellow. These Philips bulbs are great. They are "white". Some reviews on youtube or other reviews claim they're dim but they're really not dim at all if the headlights are aimed and adjusted right. They're just a tad little dimmer than the Sylvania XZE but Philips Diamond Vision is bright enough to give nice illumination of the road. I also use them on my fog lights and my high beam (H7). Now, I just need to change my parking lights which are really dim and yellowish to a whiter bulb as they now stand out. They didn't stand out when I had the Sylvanias but with these Philips bulbs, they do. I'm getting either a Philips LED or another LED brand for my parking lights. I have a 2016 Ford Fusion Energi and for that model year, they didn't have HID lights, otherwise, I would have gotten it. I didn't want the headache of installing aftermarket HID lights, so I chose the same wattage but 5000K color output instead - Philips Diamond Vision.
