Features Direct replacement for factory OEM HID headlight bulbs. Provides increase in total light output. Perfect alignment, with easy installation. True colors, with no variance. Overview Upgrade. Upgrade the headlights on your vehicle with our HID replacement bulbs! If your vehicle is equipped with HID headlights, these are a perfect direct replacement. While the factory bulbs use 25W of power, these bulbs use 35W, so they provide an increase in total light output, giving you better visibility at night. You can also improve your vehicle's styling with a cooler color temperature. Quality. There are all kinds of HID bulbs on the market, but these are the best combination of quality, without a high price tag. Manufactured in a fully automated environment, they have high output, and are DOT/SAE and ECE compliant in arc position and size. Using German quartz and American salts, no expense is spared in their construction. This leads to a long, reliable life, and excellent color. Color. While some HIDs on the market give off a green or purple tint, these bulbs will provide a pure white color on the road. These HIDs are available in true, accurate color temperatures, which we measure at our photometric test lab. The white color created by these bulbs will provide more visible light on the road, and won't cause distraction. 4300K is a natural white output, as seen on vehicles with factory HIDs. It will not have any blue tint to its color, and might appear slightly warm. 5000K is a pure white output, without any warm hint, and no tint of blue either. 6000K is our most popular color, which produces an ice white color. It matches best with most LEDs.Installation Instructions

Great Pillows
Style: Side Sleeper, Pattern Name: King
I was very skeptical about purchasing pillows online. After much research, I decided to buy two of the king size pillows. When they arrive, they were rolled up tightly in plastic. I fluffed them up and got new pillow cases for them. The first few days, I was tossing and turning. After giving them a few days, I can honestly say they are very nice pillows. Not to firm and not to soft...a very nice medium! They have a cool feeling when you lay on them. These pillows are great for those who sleep on their back AND side sleepers. No feathers have been poking out. My significant other LOVES these pillows. Been sleeping great and feel like I made a great decision getting these. Great value, great materials and great quality. I highly suggest trying these out if you're looking to replace your pillows.

Great quality but big
Style: Side Sleeper, Pattern Name: King
These pillows seem to be very good quality. I couldn’t wait to try them. I soon realized that they’re very thick & too high for my neck. I can push the pillow down but it doesn’t stay so I’d say they’re too firm for me & don’t support the neck properly because of the height.

my fav now after using 50+ pillows
Style: Back Sleeper, Pattern Name: King
I have always struggled to find the perfect pillow, and so far I have had 50+ pillows. Personally, I like my pillow to be on thinner side as I look for more support for my neck.
This is my first time buying pillows online, because I like to physically touch and feel the firmness and thickness before I purchase my pillows. I am so glad I did it! These pillows are just PERFECT for me! Perfect firmness, perfect thickness and perfect material.
One thing I suggest is that be extra cautious when you open the package. These pillows were rolled and put in a relatively thin shipping bag, so when you open with sharp objects be careful not to cut your new favorite pillows!
I let the pillows sit for about 48 hours before I started using them, but I assume you don't have to wait that long.
Overall, I am very happy with my first online pillow purchase with Serta!
