RCP D4S/D4R Xenon HID Replacement Bulbs, Pair 35W 6000K — 3200 lm Each, OEM-fit Plug-and-Play

RCP D4S6 is a pair of 35W D4S/D4R 6000K xenon HID replacement bulbs that deliver factory-style white light, higher lumen output, and long-lasting performance for HID headlamp systems.

These RCP D4S6 bulbs are designed as direct replacements for vehicles that use D4S or D4R HID lamp modules. With a crisp 6000K color temperature and high lumen output, they aim to replicate the original xenon appearance while improving visibility and durability compared with older halogen units. The bulbs are built to the same form factor and electrical specification as OEM D4S HID lamps so installation is plug-and-play without modifying the vehicle wiring or housing.

How bright are these bulbs compared to standard halogen and other HID options?

RCP D4S6 bulbs are engineered to put out significantly more light than typical halogen bulbs and outperform many entry-level HID replacements. They run at 35W per bulb with a lumen output designed to provide greater road illumination and a clearer beam pattern.

• Approximately 3200 lumens per bulb under rated conditions.
• About three times the brightness of common halogen lamps.
• Brighter than many basic xenon HID replacements while maintaining correct beam focus.

Will these fit my car and require any wiring changes?

These units are 1:1 form-factor replacements for D4S and D4R HID sockets and are made to match factory optics and connectors. Because they mimic the OEM bulb shape and electrical draw, no extra adapters or rewiring are normally needed.

• Compatible with D4S and D4R HID headlamp assemblies.
• Standard plug-and-play installation—no ballast swap in most vehicles.
• Maintains factory beam cut-off when used with the correct reflector/projector housing.

How durable are these bulbs and what protects them from the elements?

RCP builds these bulbs with high-quality quartz glass and robust internal wiring to resist heat and UV damage, extending useful life compared with lower-grade options. The construction reduces the risk of premature failure and helps keep light output steady over time.

• High-temperature, UV-resistant quartz envelope for stable output.
• Oil- and heat-resistant internal components for longevity—rated for thousands of hours.
• IP68-level sealing to reduce water ingress and short-circuit risk.

What color temperature and beam characteristics should I expect on the road?

The bulbs produce a 6000K white light with a neutral cool tint that enhances contrast and road detail without an extreme bluish cast. Properly installed in compatible housings, they deliver a focused beam pattern designed to avoid excessive glare to oncoming drivers.

• 6000K color temperature for crisp white illumination.
• Designed to preserve clear cutoff and beam focus in projector and reflector setups.
• Balanced spectral output for improved nighttime visibility.

Who is this for: The RCP D4S6 pair is suited for drivers with vehicles that use D4S or D4R OEM HID bulbs who want a reliable direct-replacement option with a crisp 6000K color, stronger lumen output than halogen, and improved component durability. Choose these if you need a plug-and-play HID replacement that maintains factory beam geometry and reduces how frequently you change bulbs.
