Innovited D4S HID Xenon Headlight Bulbs 6000K Cool White — Pack of 2, IP67 Waterproof, Up to 200% Brighter

Innovited D4S HID Xenon 6000K bulbs are direct-fit replacement high/low beam lamp units that deliver bright, cool-white illumination and long service life for vehicles specified to use D4S-type HID bulbs.

These Innovited D4S HID bulbs come as a pair and are engineered to replace factory D4S xenon lamps (compatible with part numbers such as 66144, 66140, 85140, 85415 and cross-references 66440/42402). The bulbs produce a crisp 6000K cool-white color temperature and are designed for direct swap-in installation with stock HID housings. They include an anti-UV coating, IP67-level waterproofing, and a heat-resistant metal base to protect the lamp and preserve brightness over time.

How bright are these Innovited D4S HID bulbs compared with standard units?

Innovited rates these HID bulbs at up to 200% the brightness of many factory HID lamps, improving nighttime visibility when used in compatible headlamp assemblies. Because HID systems require a short warm-up, peak output is reached a few seconds after ignition.

• 6000K color for crisp cool-white light.
• Claimed up to 200% increased brightness versus standard HID bulbs.
• Brightness stabilizes after initial arc warm-up.

Are these bulbs durable and weatherproof for everyday driving?

The Innovited D4S bulbs include features intended to extend service life and resist environmental damage: an anti-UV coating minimizes gradual dimming, and the bulbs are built to IP67 waterproof and high-temperature tolerance standards to limit fogging or vapor damage inside the lamp housing.

• Rated lifespan around 3,500 hours under normal operation.
• Anti-UV coating reduces yellowing and light loss over time.
• IP67 waterproofing and heat-resistant metal base for rugged use.

Will these Innovited D4S bulbs fit my vehicle and are they easy to install?

These bulbs are manufactured as 1:1 replacements for vehicles that originally use D4S HID bulbs. Installation is straightforward for most applications, often completed in about five minutes per side if you have access to the headlamp housing. They are NOT compatible with halogen or LED-only systems.

• Direct replacement for vehicles specified for D4S HID bulbs only.
• Typical replacement time: approximately 5 minutes per bulb with basic access.
• Not adaptable to halogen or LED stock headlamps—confirm your factory bulb type first.

What should I know about warranty, part numbers, and support?

Each pack contains two bulbs and lists several replacement part numbers to help buyers confirm compatibility. Innovited offers customer support for fitment questions or if any product issues arise—contact details are provided with the product. Keep your vehicle’s manual or existing bulb part number handy when ordering.

• Pack includes 2 bulbs; check vehicle manual for D4S requirement.
• Replaces part numbers such as 66144, 66140, 85140, 85415 and cross-references like 66440/42402.

Who this is for: Drivers who need a direct-fit D4S xenon replacement and want a crisp 6000K cool-white beam with improved brightness and protective features. This pack is suited to owners whose vehicles came equipped with D4S HID systems and who want a relatively simple, factory-compatible upgrade without changing housings or ballasts. If your car uses halogen or LED bulbs instead of D4S HID, these units are not compatible.
