Category: Automotive Parts and Accessories Product Review: Replacement for Infiniti and Nissan Xenon HID Ballast Headlight Control Unit I recently purchased a replacement for my Infiniti's Xenon headlights, which were starting to dim and flicker. I decided to go with the NZMNS111LANA control unit as it was highly rated on Amazon and seemed like a good fit for my vehicle. The installation process was relatively straightforward. The new control unit came with all of the necessary connectors, wires, and instructions. It took me about an hour to complete the job, but I'm not particularly handy with tools so it may have taken longer for someone else. Once installed, the headlights were immediately brighter and more evenly lit than before. The color temperature was also a bit warmer, which gave them a nice golden hue that looked great on my Infiniti. I've had the new control unit in for about two weeks now and it hasn't shown any signs of wear or tear. Overall, I'm very happy with my purchase. The NZMNS111LANA control unit was a good fit for my vehicle and provided a noticeable improvement in the brightness and evenness of my headlights.
