Bi‑Xenon HID Projector Lenses — Sharper Night Vision with
Bi‑Xenon HID Projector Lenses with 50,000‑Cycle Motor & Universal Fit
Swap dim factory halogens for a razor‑sharp beam pattern and dual high/low control. Precision glass optics and anti‑lock technology built to outlast your vehicle.
Three Things That Set It Apart
It’s not just the glass — it’s the motor, the mount, and the materials.
Anti‑Lock Motor
Cheaper units stick mid‑switch. The RACBOX motor uses a quality solenoid that clicks high/low reliably, even after years of daily use. No flicker, no stuck shutters.
Precision Glass Lens
The optically clear glass lens focuses light into a wide, even pattern with a sharp cutoff. No rainbow rings at the edge, no scattered glare. Just a clean, road‑wide beam.
Plug‑and‑Play Adapter Kit
Comes with H4 and H7 adapter rings and rubber seals. Whether you drive a JDM sedan, a cruiser motorcycle, or a domestic pickup, the bracket adjusts. No cutting, no drilling.
From Dark Commutes to Daylight Confidence
Installed by enthusiasts and daily drivers who want to see — and be seen.
Night drives used to be nerve‑wracking. Now the cutoff is so sharp I can see the ditch without blinding anyone. Best $60 I ever spent on the car.
Went into my ’14 Civic with the H4 kit in under an hour. The adapter rings actually fit. High beam throws light way farther than I expected.
Installed on my Yamaha. Wiring was dead simple — plug, zip‑tie, done. The body is solid metal and glass, not cheap plastic. A real premium feel.
Four stars only because I wish the high‑beam shield was carbon, but the chrome looks great. Beam pattern is perfect — no dark spots.
Took my ’98 Cherokee from candles to lasers. Every forest road feels safer. The glass lens hasn’t yellowed after 6 months of bugs and mud.
Best projector kit I’ve used in 10 years of retrofitting. The solenoid is absolutely silent. High beam clicks on instantly.
Packaging was top‑tier — each ring and seal labelled. Glass was fingerprint‑free. The chrome shroud looks like a much more expensive unit.
Put these in my son’s first car. Now I worry a little less when he drives home late. The cutoff line is crystal clear — no glare for oncoming traffic.
After three cheap Amazon projectors that failed in months, these are night and day. Built like they’re from an OEM parts bin. 50k cycles? I believe it.
Instal in Under Two Hours
No relays, no cutting — just basic hand tools and the included harness.
Remove your headlight housing
Access the factory bulb and pull the housing from the vehicle. For most models it’s a few bolts or clips. If it’s your first time, check a forum for your specific car.
Choose the right adapter ring
Match your bulb type — H4 or H7 — and snap the corresponding ring onto the projector base. The rubber seal sits behind it to keep moisture out.
Mount the projector inside the housing
Slide the projector into the reflector bowl from the front. Use the included plastic nut to tighten it. It should sit flush, with the glass lens pointing straight ahead.
Wire the harness to your factory plug
The harness has labelled connectors — high beam, low beam, ground. Plug them into the matching ports on your vehicle’s headlight socket. No splicing needed.
Bench test before sealing
Reconnect the battery, switch on the lights, and toggle high/low. The shutter should click cleanly. Aim the beam against a garage door 25 feet away — cutoff line should be level.
Reassemble and align
Seal the housing, bolt it back in, and adjust vertical aim with a screwdriver until the cutoff drops 2‑3 inches at 25 feet. That’s the legal, safe sweet spot.
Proof It’ll Outlast the Car
Built for install‑once, forget‑forever reliability.
Why This, Not That
The difference between a projector that lasts and one that leaves you in the dark.

Everything You Need, Right Here
No extra trips to the parts store. Open, sort, install.
From Squinting to Confident Clarity
Factory headlights leave you guessing what’s beyond the hood. These projectors turn night into daylight — without a full retrofit.
The Darkness Before
Standard halogen reflectors scatter light, leaving dark pools mid‑curve and blinding oncoming drivers. You lean forward, tense, hoping no deer bounds out. It’s a nightly gamble.
The Turning Point
A 2.5‑inch bi‑xenon projector with a crystal‑clear glass lens and a metal reflective cup focuses every lumen exactly where it belongs. The anti‑lock motor flips high/low instantly, rated for 50,000 cycles.
The Night Belongs to You
Clip in the H1 bulb, plug the harness, fit the adapter ring for your housing, and suddenly the road opens up. High beam floods the distance; low beam cuts a crisp, flat line that respects oncoming traffic.
Will It Fit Your Housing?
Measure first. The projector outer body diameter is exactly 2.5 inches (51mm).
