Lead the way after dusk with concentrated road-forward light. The Capra Canbus H4 LED Headlight Bulbs – 300W 30000LM are engineered as a high-output H4 dual-beam conversion that delivers powerful low- and high-beam performance in a single plug-and-play unit. Ideal for drivers demanding crisp contrast, longer sight distance and CAN-bus compatibility, the Capra H4 pair combines precision optics, robust thermal management and reliable electrical design for consistent real-world performance.

• Model: Capra H4
• Fitment / Socket: H4 (P43t) dual-beam — confirm vehicle socket before ordering
• Rated Output: 300W (system rating) / 30000 LM (combined lumen output)
• Voltage: 12V DC (automotive standard)
• Color Temperature: Bright white / daylight (~6000K typical; confirm SKU)
• Cooling: High-efficiency heatsink with hybrid active/passive thermal management (fan-assisted or fanless variants)
• CAN-bus: CAN-bus ready design to reduce dashboard error codes on many modern vehicles (decoder/resistor may be required for certain models)
• Housing: Low-profile body engineered to fit many headlamp housings — always check rear clearance
• Estimated Life: Long-life LED diodes; actual life depends on operating conditions

• Dual-beam H4 design: one bulb supports both low and high beam functions for true H4 conversions
• Ultra-high lumen output for improved highway visibility and clearer peripheral illumination
• Precision chip placement and optics to focus light on the road surface and reduce unwanted scatter or glare when properly aligned
• CAN-bus compatibility and included decoder options for many modern vehicles to avoid warning lights and flicker
• Advanced thermal control preserves brightness and extends diode lifespan under heavy use
• Plug-and-play installation on compatible H4 sockets — minimal modification required for many vehicles

• 1 × Pair Capra Canbus H4 LED Headlight Bulbs (2 pcs)
• 1 × Pair connector adapters (if required by vehicle; included items depend on SKU)
• 1 × Inline CAN-bus decoder(s) (included with CAN-bus variants or available separately)
• Installation guide, wiring notes and fitment checklist

• Confirm your vehicle uses an H4 (P43t) dual-beam socket before ordering.
• Check rear clearance in the headlamp assembly for the heatsink or fan — some engine bays require adapter plates or minor trimming.
• If a dashboard bulb error appears after installation, fit the supplied or optional CAN-bus decoder/resistor as instructed.
• After installation, have headlights aligned to ensure correct beam pattern and to avoid dazzling other road users.
• Professional installation is recommended for vehicles with complex electrical systems or if you are not comfortable with wiring.

• Always check local regulations for aftermarket headlight modifications — some jurisdictions restrict lumen output, beam pattern or color temperature for road use.
• Do not use damaged bulbs. Use the correct fuse and follow safe wiring practices; disconnect battery when wiring.
• Avoid prolonged use of improperly aimed headlights to prevent blinding oncoming traffic.
