Smart Tail Light for Everyday Riders

The Hollywood Racks Q5 mounts on saddle rails or a seat post and uses a COB LED with three brightness levels to keep cyclists visible in traffic. Its aluminium body is waterproof and houses a lithium-polymer battery. The unit weighs little and suits commuters who want a simple, rechargeable rear light without extra wiring.

Auto Brake and Light Sensors Change Daily Use

A built-in motion sensor activates the brake flash, making the light three times brighter when you slow down. Light and vibration sensors switch the flashing and breathing modes on in low light when you move and turn them off after 30 seconds of stillness. In bright daylight the light stays off automatically, saving charge for when you need it.

USB-C Charging Limits Off-Grid Range

The polymer battery delivers up to 50 hours of runtime on a single charge and replenishes via a standard USB-C cable from any computer, charger or power bank. Without a solar panel or dynamo option the light depends on grid power for long tours. Riders planning multi-day trips away from outlets must carry a power bank or accept shorter use.

Questions about this item

When will the lithium-polymer battery need replacing?

The built-in lithium-polymer cell is rechargeable via USB-C and rated for up to 50 hours of run time per charge; typical cycle life means replacement is only needed after several hundred charge cycles.

What limits continuous operation on a single charge?

Battery capacity caps run time at up to 50 hours; the light-sensing auto-off feature helps extend this by shutting the light down after 30 seconds of no vibration in low ambient light.

Does the aluminium housing get hot during all-day use?

The COB LED and aluminium body stay cool during extended rides; the light-sensing auto-off function also powers the unit down when stationary, preventing any heat build-up.
