RCP D4S/D4R Xenon HID Replacement Bulbs (Pair) 6000K 35W — 3200 lm Plug-and-Play

RCP D4S6 is a plug-and-play pair of D4S/D4R 6000K xenon HID replacement bulbs engineered to deliver factory-style bright white light and longer life for compatible HID headlight systems.

These RCP D4S6 bulbs are a direct-fit 1:1 replacement for vehicles using D4S or D4R xenon lamp modules. Each bulb runs at 35W and produces a crisp 6000K color temperature for cool white illumination, designed to match original equipment optics without requiring modifications. Built from anti-UV quartz glass and high-temperature materials, they aim to improve nighttime visibility while maintaining proper beam cutoff and minimizing glare when installed in compatible housings.

How much brighter are these bulbs compared to halogen or standard HID options?

The RCP D4S6 bulbs are rated around 3200 lumens per bulb, roughly three times brighter than typical 65W halogen lamps and about twice the output of many ordinary xenon HID bulbs. Brighter output helps illuminate farther and wider when the optics are designed for xenon systems.

• Approx. 3200 lumens per 35W bulb
• 6000K cool white color for clearer contrast at night
• Twice the typical brightness of basic xenon HID alternatives

Will these bulbs fit my car and are they easy to install?

Yes — RCP designed the D4S6 as a 1:1 factory equivalent for D4S and D4R lamp sockets, so no wiring changes or housing modifications are usually necessary. Installation is typically plug-and-play if your vehicle already uses D4S or D4R xenon modules; always consult your owner’s manual for compatibility and safety steps when replacing headlight bulbs.

• Direct-fit D4S/D4R base for most compatible vehicles
• No ballast or adapter required when replacing like-for-like
• Follow vehicle-specific access and handling precautions

How durable are the RCP D4S6 bulbs and what protects them from damage?

These bulbs use premium anti-UV quartz glass and reinforced wiring to resist heat, oil contamination, and wear, supporting an expected service life up to about 3000 hours under normal conditions. The lamp holder is made from high-temperature materials to preserve focal alignment, and IP68-rated sealing reduces the risk of water ingress that can cause failures.

• Anti-UV quartz glass to stabilize light output
• High-temperature lamp holder maintains focal accuracy
• IP68 water resistance to prevent moisture-related faults

How does the light quality affect driving at night without causing glare?

When used in proper xenon headlight housings, the 6000K color and precise focal length produce a sharp beam pattern that matches factory alignment, helping to concentrate illumination on the road rather than scattering into other drivers’ eyes. Proper installation and aiming are essential to avoid causing glare to oncoming traffic.

• 6000K cool white improves road contrast and detail
• Precise focal length preserves beam cutoff in OEM optics
• Designed to minimize glare when aligned correctly

Who is this for: The RCP D4S6 pair is aimed at drivers who need a direct-replacement xenon bulb for D4S or D4R systems and want a brighter, cooler white light with improved longevity over older halogen or lower-grade HID bulbs. Choose these if your vehicle already uses D4S/D4R HID modules, you prefer plug-and-play swaps, and you value stable output, waterproofing, and materials engineered for higher temperature operation. Always verify socket type and check local regulations regarding headlight color and output before upgrading.
