Trusted: With global distribution exceeding a half-million units over the last six years; more enthusiasts chose Morimoto over any other aftermarket ballast in the world. By adopting everything that was good about the out-going design and tossing the rest out the window, the XB55 2.0 excels in every way.

Reliability: When two of the best names in ballasts get together to create something new, good things happen. The new XB is essentially a Hylux + Morimoto mash up, and we are proud to bring their new ballast baby to North America! Designed to last for 2500 hours and we're confident they will. The powerful AS15-G4 IC chip recognizes outside system faults such as a loose high voltage connection, and after one misfire will cut power rather than potentially self-destruct. The software is proprietary to this ballast alone.

Protected: The 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 18mm body will mount almost anywhere, and that's OK because they're fully sealed from the elements. There are four mounting points cast directly into their shell, no spare brackets to mess with.

Versatile: Since the igniter cord can be unplugged from the HID ballast computer, 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 HID ballast replacements never work well with tricky CanBus systems, but the new Morimoto XB55 2.0 ballast consumes less than HALF of the start current than the previous model did. Far less than Denso, Mitsubishi, or FastBright which makes their ability to reach full intensity a more efficient process.

Modern: Like all modern OEM 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.

Functional Work of Art: Designed in California by Morimoto's engineer, Yoshi Ishida, the Morimoto XB55 2.0 HID Ballasts are just as good looking on the outside as they are well-engineered on the inside. Stainless Steel hardware. TechFlex braided insulation. Embossed circuitry on the shell. We most admire how the laser-engraved graphics on the rear incorporate the potting-ports into the design. All about the details!

Mature: The XB55 2.0 features countless advancements from the most popular OEM ballasts. In terms of modern headlight tech, High Intensity Discharge is now fully matured; and therefore the aftermarket gets the full benefit engineering progress in the OEM world. Time will tell, but we doubt there ever be an "XB 3.0" ballast from Morimoto. This could be the grand finale, folks!

Good review from cyst. 2017 honda civic ex


I installed a new one today. Between the start of 5 and 9 times, one side did not light up. I checked the connections & turned it off again. It turned on and started working! The road was very good quality.(2017 Honda civic ex 55w 5500k)


2012 hyundai sonata xb55


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.




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




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.


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!


These guys got there stuff right!


package was beyond great, product looks extremely well built , time to on is great and light is strong even in daylight! came from retro solutions digital 55w units and these flat out kick ass... will say all my lighting needs will be retrofit source from now on!!!


These take a beating


Been using them for a long time now and they take a beating. Their always onand never failed me so far. Start up right away all the time. I have so much vibration under my hood due to urethane motor mounts so their taking a beating.


Worth every dime!


Just replaced my 5+ year old D2S 35W Morimoto HID bulbs and ballasts with these D2S: MORIMOTO XB55 50w ballasts and 50w bulbs. WOW! Huge Difference!

Very happy with the light output and the new detachable igniters. Much Much easier install onto the bulbs!


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!
