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

Zreneyfex D4R 35W 4300K xenon HID bulbs are a two‑pack direct replacement designed to restore factory HID performance in compatible Toyota Prius and Avalon models.

If your vehicle originally came with D4R HID headlights and the bulbs are dimming or failing, these Zreneyfex replacements match the stock 35W power and 4300K color to return crisp, neutral white illumination. They are engineered to be plug‑and‑play for the specified Toyota model years and replace part numbers like 90981‑20029 and 42406. Important: these bulbs are only for vehicles with factory HID systems — they will not fit cars that came with halogen headlights.

Will these bulbs fit my Toyota Prius or Avalon?

Yes, when your car originally used D4R HID bulbs. Zreneyfex D4R bulbs are intended for Prius model years 2006–2009 and Avalon years 2008–2010 that shipped with factory HID lighting. They are not compatible with halogen systems or retrofit sockets.

• Direct fit for Toyota Prius 2006, 2007, 2008, 2009 (factory D4R only)
• Direct fit for Toyota Avalon 2008, 2009, 2010 (factory D4R only)
• Replaces OEM part numbers: 90981‑20029 and 42406
• Not compatible with halogen headlight systems

How is the light quality and color temperature?

These bulbs offer a neutral white 4300K color that closely matches original equipment HID output. That color balance is chosen to improve contrast on the road while minimizing the blue tint some aftermarket bulbs produce. Expect consistent, daylight‑like illumination that helps you see road markings and signs more clearly.

• 4300K color temperature for neutral white light
• Designed to reduce glare and excessive blue scatter
• Improves visual clarity compared with aged HID lamps

What power and performance can I expect?

Each bulb runs at the factory standard 35 watts, engineered to match the electrical and optical requirements of OEM ballast systems. While designed to restore original HID brightness, these bulbs are not high‑wattage upgrades — they prioritize correct output and beam pattern stability. Installation maintains safe beam alignment and compatibility with the factory housing when used in the correct D4R application.

• Standard 35W rating compatible with OEM ballasts
• Engineered for stable, consistent brightness and cutoff
• Sold as a pair to replace both headlight bulbs at once

How easy is installation and what’s in the package?

Installation is straightforward on vehicles equipped with factory D4R HID sockets — no additional wiring, relays, or adapters are required. Always disconnect the battery before handling HID bulbs and avoid touching the glass. The two‑pack ensures both sides match in color and intensity after replacement.

• Package includes: 2 x D4R HID headlight bulbs
• Plug‑and‑play fit for compatible Toyota HID systems
• Follow vehicle service manual for safe installation procedures

Who is this for: These Zreneyfex D4R 35W 4300K bulbs are for Toyota owners whose Prius (2006–2009) or Avalon (2008–2010) originally came with D4R HID headlights and need a factory‑spec replacement. Choose these if you want correct color temperature, OEM‑level wattage, and a matched pair to restore even, dependable illumination. Do not buy if your car has halogen headlights or if you need a high‑output aftermarket upgrade.
