Xentec 9007 (HB5/9004) Hi/Lo Telescopic Bixenon Hi/Lo Xenon (Both Low high Beam) 6000K HID Xenon Bulb with 35W SLBDC Slim Ballast Bundle (Ultra White)

Each bundle contain 2 bulbs, 2 ballast, and installation accessories Xenon Bulb: 2 telescopic style bixenon bulb fits socket size and color described on the title, Ballast: 35W DC digital Slim size ballast Installation: pre-assembly maybe required before installation, professional installation recommended, included relay wiring connect to one side input only. Compatibility: please check existing bulb before placing order, if not sure please check vehicle bulb reference guide, using partfinder will not guarantee fitment, 12V input required This product contain 2 bulbs 2 ballasts and accessories for standard installation 9007 “telescopic” bi-xenon HID bulbs, sometimes called sliding-shield HIDs. These use a solenoid inside the bulb that physically moves (telescopes/slides) the HID arc forward/backward to switch between low beam and high beam, instead of relying on a halogen filament. Here’s a clear breakdown: 🔧 What’s in a 9007 Telescopic Bi-Xenon Kit 9007 Bi-Xenon HID bulbs (with solenoid motor built in) HID Ballasts (one per side) Bi-Xenon Relay Harness (connects to your car’s factory 9007 socket) 12V battery & ground leads (power supply for ballasts and solenoids) ⚡ Wiring Concept The HID ballast powers the HID bulb for both low and high beams. The solenoid inside the bulb moves a shield or the bulb itself to change beam pattern: Low Beam → Shield partially blocks arc (cutoff line). High Beam → Solenoid retracts, exposing full arc. Your factory 9007 plug acts as a signal trigger only, not the direct power source. 🔌 Installation Steps Remove stock 9007 bulb from headlight housing. Insert HID Bi-Xenon bulb into the housing and lock in place. Mount the HID ballast in the engine bay (close to headlight, away from heat and water). Connect ballast to HID bulb (usually a 2- or 3-pin plug). Install relay harness: Plug harness into one factory 9007 socket (usually driver side) (acts as trigger for both sides). Connect harness to both HID ballasts. Connect harness red wire to battery (+). Connect harness black wire to ground (–). Plug solenoid connector (usually 2 small wires) from bulb into harness (this activates telescoping motion). Test beams: Switch ON low beam → HID lights, shield down (cutoff). Switch ON high beam → Solenoid retracts, HID arc exposed for full high beam. Tips & Troubleshooting If only one side works, double-check that: The harness plug matches orientation (sometimes reversed = no trigger). Both ballasts are connected securely. Grounds are solid (bad ground = one side won’t fire). If high beam doesn’t work, check that the solenoid 2-pin plugs are connected and not reversed. Some harnesses let the HID stay ON during high beam; others cut HID during high. Make sure you bought the style you want.
