SEALIGHT 9005/9006 LED Headlight Bulbs, Pack of 4 6500K Cool White — IP68 & 15,000RPM Fan

These SEALIGHT HB3/HB4 bulbs are engineered to replace factory halogen bulbs without complicated wiring, offering dramatically improved nighttime visibility and a crisp 6500K color temperature. The set ships as a pack of four and includes built-in decoders and a robust cooling system so the lights run reliably in daily driving conditions. Rated IP68 for water resistance and built to aerospace-grade standards, they balance brightness, beam control, and longevity for most modern vehicles.

How much brighter are these compared with stock halogens?

Expect a substantial increase in brightness and perceived range: SEALIGHT advertises up to 8× the brightness of standard halogen bulbs, with system output figures cited up to 100,000LM and a typical paired output around 80,000LM. The higher lumen intensity and 6500K color temperature create a whiter, more contrast-rich beam that helps you see road detail and signs sooner.

• Up to 8× brighter than conventional halogen bulbs
• Typical paired output ~80,000LM; system peak figures up to 100,000LM
• 6500K cool-white color for sharper road contrast
• 120W output per pair (nominal factory comparison basis)

Will these bulbs fit my car and work without dashboard errors?

SEALIGHT includes a smart CANbus decoder and claims 99% vehicle compatibility to prevent flicker or error codes on most cars. Because some specialty or European models use unique wiring, you may occasionally need an additional decoder—contact SEALIGHT support if your vehicle shows an error.

• Plug-and-play design mirrors factory halogen shape for easy installation
• Includes decoder to reduce flicker and dashboard warnings
• Works with 99% of vehicles; verify bulb type before purchase
• Extra decoder available from manufacturer for special models

How is heat managed and how long will the bulbs last?

Thermal control combines aerospace-grade aluminum housings, precision heat sinks, and a high-speed 15,000 RPM turbo cooling fan to keep operating temperatures low. That cooling system, together with quality components, supports a service life rated over 60,000 hours under typical conditions.

• Aerospace-grade aluminum body for efficient heat dissipation
• 15,000 RPM turbo fan for active cooling
• Precision heat-sink design minimizes thermal stress
• Rated life exceeding 60,000 hours

Are these bulbs weatherproof and durable for regular use?

Yes—these SEALIGHT LEDs are rated IP68 for protection against dust and prolonged water immersion, making them suitable for wet roadside conditions, rain, and splash-prone environments. The sturdy construction and corrosion-resistant materials help maintain consistent output over time.

• IP68-rated housing resists dust and heavy moisture
• Corrosion-resistant materials for long-term durability
• Pack of four for front and spare or two-vehicle installs
• Included accessories support straightforward replacement

Who is this for: Drivers who want a straightforward, high-brightness upgrade from halogen headlights without complex wiring or frequent replacements. These bulbs suit commuters, night-shift drivers, and anyone seeking a whiter light and improved long-range visibility—provided your vehicle uses 9005/9006 (HB3/HB4) sockets. Confirm compatibility with your vehicle model and, if needed, request an additional decoder for special electrical systems.
