The Lezyne Helmet Fusion Drive 500+ is a helmet-mounted LED front light suited to riders who need high-output weather-resistant visibility across varied riding conditions and disciplines. Producing up to 500 lumens with a maximum runtime of 35 hours the light pairs a modern optical design with a CNC-machined aluminum body featuring integrated cooling fins — a construction approach that balances thermal management with durability in a compact form factor. The unit charges via a water-resistant USB-C port and carries an IPX7 waterproof rating making it a reliable option for unpredictable weather. Mounting is handled through a GoPro-style helmet interface paired with a high-strength composite mount and non-slip padding; a versatile Velcro strap secures it to most helmet designs. The Helmet Fusion Drive 500+ is compatible with the Lezyne Infinite Light Power Pack XL+ for extended-range riding.
