LED Bulb P21/5W-BAY15D - UltraBoost 24V White– High power, fanless

Discover our new generation of P21/5W-BAY15D UltraBoost LED bulbs, specifically designed for trucks, heavy-duty vehicles, and construction vehicles operating on 24V to 50V, with exceptional luminous power, without fan or noise.

This version features a dual function:

• High power / Low power: for brake lights / rear position lights or for daytime running lights / front position lights

The UltraBoost LED is equipped with 39 high-quality American CREE white LED chips, distributed over the entire body of the bulb to ensure optimal heat dissipation and homogeneous 360° lighting. At the front, 9 additional LED chips project light directly forward — ideal even if the reflector is damaged or worn.

• High power without fan: 0 noise, 0 maintenance, enhanced reliability
• Without integrated resistor: reduced consumption, optimal thermal compatibility
• 360° lighting + front beam: maximum efficiency even on aging optics
• Voltage range 24V to 50V: perfect for trucks, buses, utility vehicles, and construction machinery
• Good anti-error level: compatible with the majority of non-Canbus or low-sensitivity heavy-duty vehicles
