UltraBoost P21W BA15S LED Bulb Reverse White – High power, fanless

Discover our new generation of P21W BA15S UltraBoost LED bulbs, specially designed to offer exceptional luminous power without a fan or noise. This LED incorporates 39 American CREE LED chips, distributed all around the bulb for optimal heat dissipation and homogeneous lighting. On the front, 9 additional LED chips ensure direct light projection, ideal even if your reflector is damaged.

• High power without fan: no noise disturbance
• Without integrated resistor: lower consumption and better thermal compatibility
• 360° distribution + front beam: perfect for lights with worn or degraded optics
• Extended compatibility: good anti-error level on most French, Japanese, and old vehicles (before 2000)

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