What's the Word

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 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.

Focus: Since 2005, we have focused our efforts on lighting and that's it. Experience means we know the products. We know the technology. We know our competitors, and most importantly, we know our customers. We like to wrench. We like to drive, we like to ride, and like you: we demand the best for whatever it is that gets us going. That's why at LED Concepts; we only stock the shelves with today's best, brightest, and most badass LED Lighting upgrades.

Installed this on my 8th gen accord Coupe coupled with H11B bulbs
And all I can say is that I didn't have any light output before :)
Now it's AMAZINGLY bright and intense and focused light on the road
Warm up time is pretty fast ( Not OEM but still pretty fast ) and the light output is AMAZING
Highly recommended

Great product

I had to order these as an updated replacement for my previous system and these are smaller and slimmer then the older ones from TRS. They start up right away every time and I have not had any issues at all with them. I would recommend these!

I purchased these ballasts with a whole setup in April 2016. They have been super bright and solid all around. Up until 1 month ago I was super happy with them. I noticed that one of my headlights wasn't working. After troubleshooting I realized that my ballast had gone out. I would have turn my headlights on and off one or twice to get the headlight to start working again. Overtime the problem began to get worse. After a month I couldn't get it to turn on anymore. I am currently looking for another one just like this. The other ballast works great. It's probably just a defect ballast. I am definitely going to continue using this part though.

Slim style ballast with plenty of power and has professional wrapping around cables with oem style connections. So far these warm up about 10sec to full which is good, their are quicker ballasts out there but those quick firing ones hurt your bulb life! These are metal strong made ballasts with a good warranty. Good metal mounting options or space on back to put some 3M.

XB55 is a great little ballast.

Fit and finish is great, mounting brackets offer lots of options, and it strikes a perfect combo between efficiency and warm up time.

My headlights are at or near full brightness within 10 seconds, and I have verified on the bench using a programmable power supply that transient startup currents never exceed just north of 6A, allowing many to install without a relay harness. Relays are always recommended of course, but none the less.

They also both settle out at 4.9A @ 12.6V after just 3-4 seconds, meaning these are actually pulling 60W from the car's system, which after efficiency losses (based on how hot it gets) translates to right at 55W at the bulb - exactly as advertised!

I have zero regrets! I love them!
