Osram D3S 66340CB Cool Blue HID Xenon Headlight Bulbs | Pack of 2

Strong light output, clean color and good consistency. The 5500K shade is exactly what I was hoping for.

Excellent replacement for worn factory xenons. Very bright, nice white color and no flickering or startup issues. Definitely satisfied with the performance.

I’ve been using these for several months and both bulbs still match perfectly. Very happy with the performance.

Excellent replacement if you’re trying to keep the factory HID setup but want a whiter, more contemporary appearance.

Huge improvement compared with the worn xenons I removed. I didn’t realize how much brightness the old bulbs had lost.

I�ve had these installed for a while now and they continue to perform perfectly. Both bulbs remain evenly matched with strong light output.

The color looks great at night, especially through projector lenses. Bright white with a subtle blue edge at the cutoff.

Very satisfied. Fit was identical to the original D3S bulbs and the electrical connectors locked in properly.

Nice balance between style and visibility. The white output makes the car look newer without being excessively blue.

A worthwhile refresh for an older HID system. The headlights look much brighter compared with my original bulbs.

Both bulbs fired immediately and have remained perfectly stable. No flickering and no difference in color from side to side.

I previously had 6000K aftermarket bulbs and prefer these. The color looks more natural while still being noticeably cool white.

Installed them in factory projector housings and the result is excellent. Sharp beam and clean white color.

Great output from these D3S bulbs. They are whiter than stock but still provide plenty of useful road illumination.

OSRAM continues to be my first choice for xenon bulbs. Excellent fit and consistent performance.

Bought these after one factory bulb started changing color. Replacing the pair restored a perfect match.

The 5500K color is excellent. White on the road with a little blue visible around the projector cutoff.

Very pleased with these. They give the front of the car a newer appearance without changing the factory HID system.

Noticeably better than my old HID bulbs. Night driving feels much more comfortable with the fresh light output.

I am very impressed with these HID Xenon Bulbs, I highly recommend them. Product arrived on time and in excellent condition. Thank you.

Great upgrade from the factory bulbs. The color is a crisp white without looking overly blue. Night driving is much more comfortable now.

The brightness and color are very consistent between both bulbs. Exactly what I wanted from an OEM-quality product.

I was worried they might be too blue, but they’re not. Mostly bright white with a subtle cool appearance.

Very impressed with the brightness. The light output is noticeably stronger than my old bulbs, but it still has a clean OEM appearance.

Great D3S replacement. No coding, errors or other problems after installation.

These transformed the appearance of my headlights. Much cleaner than the original bulbs that had thousands of hours on them.

Very nice white light. Both sides are uniform and the output is strong across the entire beam pattern.

The bulbs needed a little operating time before the color completely settled, but now they look excellent.

Excellent color temperature for anyone who thinks 4300K looks too warm but doesn’t want extremely blue headlights.

I specifically wanted OSRAM instead of generic D3S bulbs. The quality difference is definitely noticeable.

Great upgrade. The headlights look cleaner and road signs are very easy to pick out at night.

These look almost LED white but maintain the excellent beam pattern of the factory xenon system.

High quality bulbs with smooth startup and stable output. No flickering whatsoever.
