P21W-BA15S LED Bulb - UltraBoost Red, Stop or Fog Light – High power, fanless

Discover our new generation of P21W BA15S UltraBoost LED bulbs with red lighting, specially designed to offer maximum luminous power for use as brake or rear fog lights — all without a fan or noise. This bulb features 39 American-quality red CREE LED chips, distributed all around the bulb to ensure optimal heat dissipation and uniform lighting. On the front, 9 additional LED chips project light directly, maintaining excellent visibility even if the light reflector is damaged.

• High power without fan: total silence, no moving parts
• No integrated resistor: reduced consumption and improved thermal compatibility
• 360° lighting + front beam: ideal for lights with aging or tarnished optics
• Extended compatibility: good anti-error level with most French, Japanese, and older vehicles (before 2000)

⚠️ Important: For recent or very sensitive German vehicles (BMW, Audi, Mercedes…), prefer our fan-cooled models with integrated resistor, specially designed for strict Canbus systems.
