Very good color consistency from left to right. No flickering or startup issues.

Alex N.

Really nice color temperature. White enough to look modern but not so blue that visibility suffers. Great choice for an HID upgrade.

J
Jenna R.

Nice balance between a cooler color and usable nighttime illumination.

Great upgrade from my standard D4S xenon bulbs. The light looks noticeably whiter and more modern.

Excellent option if you like the performance of xenon but want something whiter than the standard OEM color.

Replaced my aging D4S bulbs and the improvement in both brightness and color was immediately noticeable.

Very clean white xenon appearance. Both bulbs matched nicely after they had some time to warm up.

K

The headlights look much newer now. Clean cool-white color without an extreme blue or purple appearance.

I wanted to refresh the appearance of my factory HID headlights without converting to LEDs. These did exactly that.
