Remove the original headlights
Free the front bumper cover: the Prius headlight is captured behind the bumper cover edge. Release the upper clips and the fender-side fasteners far enough to draw the cover clear of the lamp.
Unbolt the headlight and support it as the last fastener comes out.
Disconnect the wiring: press the lock tab and pull on the connector body, not on the wires.
Compare before fitting: hold the RIGNOX lamp against the original and confirm mounting tabs and plug position.
Install the RIGNOX headlights
Connect the lamp to the factory connector and confirm the lock tab clicks home.
Test before closing up: confirm low beam, high beam, the white daytime running light, the amber side marker, the sequential amber turn signal and the startup animation.
Seat and bolt the lamp, checking the gap against the fender, hood and bumper cover before tightening.
Refit the bumper cover, then repeat on the opposite side and reconnect the negative battery terminal.
Electrical and function test
- Confirm low beam and high beam on both sides.
- Confirm the white daytime running light and the amber side marker.
- Confirm the sequential amber turn signal and hazards.
- Confirm the startup animation on ignition.
- Check for dashboard warnings, flicker or hyperflash.
- Verify beam aim against a flat vertical surface.
Troubleshooting
- One lamp does not light: recheck the connector lock, the related fuse and the battery connection.
- Hyperflash or a dash warning: confirm both sides are wired the same way and every plug is fully seated.
- Body gaps look uneven: recheck that the bumper cover is fully re-clipped over the lamp edge before adjusting the lamp itself.
- Moisture appears: light condensation may clear as the lamp warms; document heavy or persistent moisture with photos.
