Zreneyfex D4R 35W 4300K Xenon HID Headlight Bulbs 2-Pack — Direct-Fit for Toyota Prius (2006–2009) & Avalon (2008–2010)

If your vehicle originally came with D4R HID headlights, these Zreneyfex bulbs provide a direct-fit replacement rated at 35 watts and a 4300K color temperature for clear, neutral-white illumination. They are designed to replace OEM part numbers such as 90981-20029 and 42406 where the factory system uses D4R xenon bulbs. These are not compatible with vehicles that use halogen systems; confirm your car’s stock bulb type before ordering.

Will these bulbs fit my Toyota Prius or Avalon?

Yes—if your car left the factory with D4R HID headlights. The Zreneyfex pair matches the D4R base and electrical interface used by many Toyota HID systems during the listed years. Do not install these in halogen housings or cars that originally came with halogen bulbs.

• Direct replacement for Toyota Prius 2006, 2007, 2008, 2009 (D4R HID only)
• Direct replacement for Toyota Avalon 2008, 2009, 2010 (D4R HID only)
• Replaces OEM numbers such as 90981-20029 and 42406 where applicable
• Not compatible with halogen headlight assemblies

How does a 4300K xenon bulb affect night driving?

A 4300K xenon light produces a neutral white beam that enhances contrast without appearing overly blue. This color temperature is widely used in OEM HID systems because it balances visibility and glare control, providing clear roadway illumination while working with projectors and reflectors designed for HID. Expect a whiter look compared to halogen, which can aid in identifying road signs and lane markings.

• 4300K delivers neutral-white daylight appearance
• Designed to work with factory HID projectors and reflectors
• Improves contrast for markings and roadside details
• Less perceived glare than higher-K blue-tinted bulbs

What performance and installation points should I know?

Each Zreneyfex bulb is rated at 35 watts and built to meet the electrical and mounting requirements of D4R HID systems. Installation is typically plug-and-play for vehicles with genuine HID ballasts and connectors; no modifications are needed when replacing an existing D4R bulb. Always handle xenon bulbs carefully and avoid touching the glass surface to preserve lifespan and output.

• Power rating: 35W per bulb, compatible with OEM HID ballasts
• Plug-and-play with original D4R connectors and housings
• Pack includes two D4R HID bulbs for axle replacement
• Do not touch glass; use gloves or a clean cloth during installation

Are there any cautions or compatibility limits?

These bulbs are intended purely as replacements for factory D4R xenon systems and will not operate correctly in halogen-only wiring or housings. If your vehicle has aftermarket ballasts or adaptive headlight modules, verify their compatibility before swapping bulbs. Installation by a qualified technician is recommended when vehicle systems have been modified.

• Not compatible with halogen headlight sockets or housings
• May require ballast compatibility check in modified setups
• Professional installation recommended for vehicles with nonstandard electronics
• Confirm part number fitment (90981-20029 / 42406) before purchasing

Who is this for: Drivers who own Toyota Prius models from 2006–2009 or Toyota Avalon models from 2008–2010 that originally shipped with D4R HID headlights and need a reliable, OEM-style xenon bulb replacement. Choose Zreneyfex if you want a direct-fit 35W 4300K option that matches factory color temperature and mounting without requiring wiring changes. Not suitable for vehicles that came with halogen bulbs or for buyers seeking aftermarket color-tinted HID conversions.
