UltraBoost W21W 7440 LED Bulb Reverse White – high power, fanless

Discover our new generation of W21W 7440 LED bulbs UltraBoost, specially designed to deliver exceptional light output without a fan or noise. This LED integrates 39 American CREE LED chips, distributed all around the bulb for optimal heat dissipation and uniform lighting. On the front, 9 additional LED chips ensure direct light projection, ideal even if your reflector is damaged.

• High power without a fan: no noise nuisance
• Without integrated resistor: lower consumption and better thermal compatibility
• 360° distribution + front beam: perfect for lights whose optics are worn or degraded
• Extended compatibility: good anti-error level on the majority of French, Japanese and older vehicles (before 2000)

⚠️ Please note: for recent or very sensitive German vehicles (BMW, Audi, etc.), we recommend our ventilated models with integrated resistor, better suited to demanding Canbus systems.
