Review: 自転車用ウィンカーの現状唯一の選択肢 - ウィンカーとして使用。とても輝度が高く、視認性は良好。 充電方法は無線充電のみ。 充電中は赤ランプが点灯するが、熱を持つと黄色ランプに変わり充電は停止する。 一度この状態になると充電台から外して冷ますまで充電は再開されない。 普通の無線充電器を使っている限りはこのサイクルが7,8回は必要。 カシムラKW-66などの冷却機能付きスタンドを使えば1回で最後まで充電できる。 Review: WORTH IT! - These are SO bright. They work beautifully and last for hours on a single charge. I enjoy that they are watertight so I don’t have to worry about them when it’s rainy and I’m commuting on my bike. ## Features - Synchronized Flashing: Increase visibility and safety with Lumos bike light's synced lights that create a larger visibility footprint, making it easier for motorists to spot and gauge your size and distance. - Turn Signals & Automatic Brake Lights: Activate turn signals using a Lumos Remote (sold separately) or smart devices, while built-in brake lights (activated via Lumos Remote) warn drivers when you slow down, preventing collisions. - Flexible Placement: Each lumos bike light features red, white, and yellow LEDs, allowing it to function as a front, rear, or turn signal light.
