HID Headlight Igniter Bulb Socket W3T216 for Mazda 3 CX-9 CX-5 Honda CR-V CR-Z
Replace your failed xenon ignitor and restore full headlight brightness. Direct OEM replacement that ends flickering, dim output, and headlight failure.
Fix Flickering Xenon Headlights Fast
Factory xenon (HID) headlights deliver exceptional nighttime visibility—until the ignitor fails. When that happens, you'll notice flickering, delayed startup, dim output, or complete headlight failure. This D4 ignitor is the direct-replacement component that restores your factory xenon system to proper operation.
Xenon systems require a high-voltage ignitor to create the electrical arc that illuminates the bulb. When this ignitor degrades over time, your headlights suffer. This replacement delivers the precise voltage your D4 xenon bulbs need for instant, reliable startup and consistent brightness.

Installation requires accessing the rear bulb area, disconnecting the failed ignitor, and connecting the new unit. Process typically takes 20-40 minutes per side. If both headlights show symptoms, replace both ignitors to prevent future issues.
