No Comparison: When it comes to HID bulbs, Morimoto has always brought us the best in the aftermarket, and their latest examples are no exception. Sure we think the options from Philips and Osram are great too, but when it comes to bang for the buck - nothing compares to the Morimoto XB HID lineup. Designed for boosted 50W+ ballasts, The XB's will produce more lumens, last longer, project farther, and look better doing it.

XB50: New for 2018! Until now, there hasn't been a high quality, high output D2S HID bulb since the oldschool Philips DL50! While the XB50 wont magically make your headlights any brighter on boosted ballasts: They will have a longer lifespan, resist premature wear, be more reliable, and maintain their rated Kelvin rating rather than yellowing out like bulbs designed for a 35w system would. Solid choice for those who want the most output from their system!

Lumin Osity: At the heart of the XB D2S bulbs is their perfectly aligned 100% Philips quartz glass that houses a capsule from APL-USA. Using high quality halide salts from German-supplier Messer; the bulbs produce nearly the same lumin Osity (intensity) as the amazing Osram CBI bulbs at 5500K. No, you're not seeing things here, but yes you will be seeing everything at night.

Long Life: The Austrian-sourced Plansee electrodes help keep the bulbs running brighter for longer. In comparison to a Philips bulb with 200 hours of use; the Morimoto will maintain 83% of it's intensity whereas the Philips bulb will retain 86%. Yeah, the Philips maintains a little longer, but this kind of longevity is unheard of in the aftermarket. We're impressed!

Precise Alignment: Morimoto's Symmetry-Structure frame surrounds the base of the glass capsule keeping everything properly lined up, which is paramount when it comes to HID bulbs. In the past we all agreed that precision wasn't the strong suit for the XB bulbs... But the latest are indeed the greatest - and they're now consistently well-aligned, which is a good thing - because it means the output is also consistently bright and uniform throughout. [Applause]

Reliability: Not that we recommend this for any HID bulb, but go ahead and fire it up 100 times in a row or even run it underwater for days at a time and the difference between the XB and any so called "competition" will be clear. These bulbs will even work with OEM Nissan/Infiniti (Matsushita/Panasonic) ballasts, which are notorious for compatibility problems on anything aftermarket.

Compliance: The XB replacement HID bulbs are built to industry-standard specifications and meet/exceed all SAE, DOT, and ECE requirements, making them a perfect match for a replacement bulb or upgrade! They have been tested for reliability with all ballasts from Morimoto, Denso, Hella, Bosch, and Koito and passed with ease.
