Product Details

Trusted: With distribution exceeding 150,000 units over the last four years; more enthusiasts chose Morimoto over any other aftermarket ballast. Easily filling the shoes of the 5Five units that they replace, the brand new XB55 ballasts excel in every way.

Inspired: Packaged into a more retrofit-friendly design, the new XB's feature countless elements derived from the most popular OEM benchmarks. As good as they are, even arrogant retrofitters may start second-guessing those bulky, power hungry, exposed-to-the-elements, OE ballasts. Educate yourself on some of the differences in this video.

Protected: Their die-cast aluminum shell houses a 100% potted circuit board; eliminating any chance of moisture damage. The AMP SuperSeal three-pin connector from TE Connectivity between the igniter and the ballast ensures the safety of this crucial output.

Compact: Slim 17mm body will mount almost anywhere with their extremely functional and attractive eight-position mounting brackets.

Versatile: If you're like many of us retrofitters, the setup is always changing and now your ballasts can keep up! Since the igniter cord can be unplugged from the ballast, you can easily change from AMP to D2S or Vice Versa. (without the use of unreliable adapters, that is) Likewise, if an igniter does happen to go bad, it can easily be replaced.

Fast, Friendly and Efficient: Power hungry ballasts never work well with tricky CanBus systems, but the new XB55 ballast consume < 5A on ignition without compromising their reasonably quick warm up speed. That's much less than Denso, Mitsubishi, FastBright, and the old Morimoto too, which makes their ability to reach full intensity a more efficient process.

Quiet: Like all modern OEM D1 and D2 ballasts: the XB has relocated igniters far closer to the HID bulb. The lack of high voltage transmitted through wiring drastically reduces EMI/RFI (radio interference). Total system reliability is also improved by shielding the main circuit board from the static produced by these high voltage bursts on start up.

Reliable and Smart: The XB55 ballasts are designed to last for 2500 hours and there's not much that will stand in their way. The matured DSP 2.0 software recognizes outside system faults such as a loose high voltage connection, and after one misfire will cut power rather than potentially self-destruct.

Functional Works of Art: Designed by Artur Saakyan in California, the Morimoto XB55 Ballasts feature a gunmetal paint job. Laser etched graphics. Stainless Steel hardware. Color coordinated mounting bracket and TechFlex braided insulation.

Excellent + the 2-year warranty

I accidentally bought this instead of the XB35 in a hurry to get it shipped before the weekend for my Subaru STi headlights (factory D2S HID projector) I acquired recently as the halogen projector was just not cutting it for my WRX. I already had the Xenarc XHB 6000K bulbs and was worried that this 55W may actually drive the color down to 4000K with yellowish hue like the old Philips bulb did but glad I actually went with the 55W. Yes, I'm very much aware I'll shorten the bulb's lifespan but the light is very much even and with the 55W, the beams go much wider with a crisp output. The bracket is nice since I can mount them in tight spot or if need be, use heavy duty zip ties to keep them in place. No issue with water or moisture getting in. The connector fitment is tight and feels like a quality product. The 2-year warranty from a US company is just easier to deal with as I've had bad ignitor in the past and TRS was always helpful so the support and service you get, you definitely get what you pay for. Sure, I could spend more and go with OEM but at the time this made the most sense so I'll stick with this for now until I need to upgrade or change my setup.

I couldn't see any difference between this ballast and OEM ballast except this one is giving me the power which the OEM ballast cant!. I used it for more than one year using D2S Osram CBI and the output was AMAZING. Highly recommended.

Swapping out my OEM 35watt HID ballast to Morimoto True 50watt ballast with the xb3/5 Hid bulbs, the difference is day and night. No matter how much pictures out there on the Net that compare the 35watt hid vs 50watt , there is nothing like experience it in person! . No matter you got projector or reflector housing headlight 50watt Morimoto XB55 is the way to go.....

Here is the few things describe about the unit, ballast are slim, fell very very solid, the wiring are top of the line well made and my favorite parts of the unit is the new Orange! mounted bracket ... the Only thing that give me a hard time is the ignitor it a bit big :( ...... Oval all this the very best aftermarket HID you can buy period ..... oh one more thing can you include the old ballast mount bracket too....
