Review on HID Ballast with Ignitor - Headlight Control Unit for Nissan & Inifiniti Vehicles - Murano, Maxima, Altima, 350Z, QX56, G35, FX35 - Replacement for 28474-8991A, 28474-89904, NZMNS111LANA by Chris Sweeton

I started having problems with one of the HID headlights on my 2009 Nissan Altima. At first I thought it was a burned out lightbulb. So I replaced the HID bulbs but the problem persisted. During the investigation, I realized that the ballast could be the source of the problem. I took a chance and bought a replacement HID ballast from GWA Auto Parts. The part arrived very quickly and took me about 20 minutes to install (I knew exactly which screws to remove). To my SURPRISE, this solved my problem and the old headlight bulb even worked. This was a quality OEM HID ballast replacement for my 2009 Nissan Altima.
