Giro ROC Loc 5 LED Helmet Rear Light — Black One Size, Rechargeable & IP65 Rated

The Giro ROC Loc 5 LED is a compact, rechargeable helmet-mounted rear light that snaps into your helmet's fit dial to give high-mounted, weatherproof visibility for road and commuter cycling.

Designed to integrate directly with Giro helmets that use the ROC Loc 5 fit system, this accessory light sits at the highest point of the head for clearer sightlines to drivers and fellow cyclists. It eliminates bulky strap mounts by snapping into the existing fit-wheel, stays secure through rough roads thanks to a water- and grit-resistant housing, and offers selectable flash and solid output to suit different riding conditions. Rechargeable via micro-USB, the unit balances runtime and brightness so you can tailor output to commute or nighttime use.

How does the ROC Loc 5 LED attach to my helmet and stay in place?

Attachment is tool-free and uses the helmet's existing ROC Loc 5 dial assembly, creating a snug, integrated fit without extra straps or adhesives. Because it mounts at the fit-wheel, the light sits at the helmet's top-rear, reducing movement and maintaining the helmet's original fit and balance.

• Snaps directly into the ROC Loc 5 fit-wheel—no aftermarket mounts required
• Low-profile design preserves helmet aerodynamics and balance
• Secure connection resists bouncing and shifting on rough terrain

What are the brightness, modes, and battery performance?

The light offers two selectable illumination modes: a flashing mode for extended visibility and a solid mode for continuous illumination. It delivers up to 30 lumens in flash mode for about 10 hours and around 20 lumens in solid mode for roughly 2 hours, providing flexible runtime depending on your route and ambient light.

• Flash mode: 30 lumens, approximately 10 hours runtime
• Solid mode: 20 lumens, approximately 2 hours runtime
• Built-in three-stage LED battery indicator for quick charge checks

Is the light durable and suitable for all-weather riding?

The ROC Loc 5 LED is built to an IP65 rating, which means the housing protects the electronics from water jets and road grit so it performs reliably in rain and spray. Its robust casing and secure attachment make it a good match for daily commuting and variable-weather weekend rides, while the quick 2-hour recharge window minimizes downtime.

• IP65-certified water and grit resistance for rainy conditions
• Durable housing resists road debris and splashes
• Fast micro-USB recharge—full charge in about 2 hours

How easy is it to use day-to-day?

Operation is straightforward: snap it into the fit-wheel, use the single control to toggle modes, and monitor battery status via the integrated LED indicator. Micro-USB charging and a short recharge time make it simple to top up between rides, and its one-piece integration avoids fiddly straps or loose mounts.

• Single-button control for quick mode switching
• Three-stage battery indicator shows remaining charge at a glance
• Micro-USB port for common, convenient charging cables

Who is this for? The Giro ROC Loc 5 LED accessory light is ideal for riders who already own a compatible Giro helmet and want a clean, high-mounted rear light that preserves helmet fit and aesthetics. Commuters, urban cyclists, and anyone who rides at dawn, dusk, or night will appreciate the elevated visibility, weatherproof construction, and rechargeable convenience. It’s especially useful for cyclists who prefer integrated solutions over external strap mounts and value a quick recharge and reliable run time for daily use.
