Osram’s CBI D4S bulbs are the way to go if you’re looking for awesome color (5000k), with zero lumens loss – In short, they rock!

Factory / OEM D4S bulbs are usually rated at 4300k, which means that you’re headlights just look “boringly” white. In the past, the only way to get more color was to go with higher kelvin (K) D4S HID bulbs, which resulted in less useable light output (less lumens) - Until now. Osram has stepped up to the plate, and introduced their Xenarc 66440 CBI (mercury-free) bulbs, which offer awesome 5000K color temps – with absolutely no light loss.

No blue coatings, no gimmicky ratings – just pure performance and looks to boot!

Osram CBI 66440 CBI bulbs come with an IEC PK32d-2 D4S base. Check out our industry leading Shop By Vehicle tool if you’re not sure that this is the right bulb for your vehicle
