H4 GTR Ultra Series HID Bulbs (HighLow)

Upgrade your vehicle’s lighting performance with GTR Ultra HID Bulbs, engineered for precise beam control, increased brightness, and reliable long-term performance.

Designed for H4 halogen applications, each GTR H4 HID bulb is laser-aligned within the bulb base to match the factory H4 bulb’s exact focal position. This precision ensures the HID light source sits correctly inside the reflector housing, helping maintain a clean and controlled beam pattern while maximizing visibility.

Built using premium German Philips UV quartz glass, these bulbs provide excellent durability and help protect your factory housings from harmful UV exposure. Compatible with 35W and 55W HID ballasts, they include AMP-style connectors and high-quality wiring for a proper plug-and-play installation.
