自行车电子车灯（可显示电量的自行车车灯）

新华网北京4月8日电 据美国科技博客Gizmodo报道，在自行车上安装车灯可以保障你在夜间的行车安全，当然，车灯发出的必须是可见光。当车灯没电的时候，你就像一个司机很难注意到的影子。Eagle 600 可充电车灯不仅自恃可以发出600流明的光，同时，它还拥有一个可以让你准确知道剩余电量的内置有机发光显示器。

Eagle 600能发出如此大的光亮是因为它配备了一对发光二极管，3100毫安时的电池可以支持电池在最大强度下持续发光1个半小时。但是你也可以把亮度调低，或者改用闪光模式。微型的自然光显示器会在同一时刻根据你选择的模式显示车灯可工作的时间。

Eagle 600是完全防水的，充电也很简便，只需要通过车灯背面封闭的USB接口就能完成。此外，车灯还配有一个可以从车把上速卸的底座，在夜晚修理的时候可以把车灯拆卸下来。Eagle 600 价格不菲，160美元的标价没有美化的必要，然而，如果你在夜间有过因车灯没电而涉险的经历，那Eagle 600 或许真的物有所值。

A Rechargeable Bike Light That Tells You Exactly When It Will Die

The lights strapped to your bike only keep you safe at night as long as they're visible. When they die, you're just another shadow that drivers barely notice. So not only does the rechargeable Eagle 600 boast a whopping 600 lumens of light, it's also got a built-in OLED display letting you know exactly how much longer it will stay lit.

A pair of LEDs is actually what lets the Eagle 600 produce so much light, and at full intensity its 3,100 mAh battery will keep them running for about an hour and a half. But you can boost that runtime with a lower intensity setting, or activating the bike light's flashing mode. And all the while the tiny OLED display will show you the estimated runtime based on whatever setting you're using.

The Eagle 600 is also completely waterproof, can be easily recharged via a sealed USB port on the back, and comes with a quick-release mount for your bike's handlebars so it can be removed for quick night-time repairs. At $160 there's no sugarcoating the Eagle 600's expensive price tag, but if you've ever had a run-in with a nasty car at night because your bike light died, it just might be worth it.
