新華網北京4月8日電 據美國科技博客Gizmodo報道，在自行車上安裝車燈可以保障你在夜間的行車安全，當然，車燈發出的必須是可見光。當車燈沒電的時候，你就像一個司機很難注意到的影子。Eagle 600 可充電車燈不僅自恃可以發出600流明的光，同時，它還擁有一個可以讓你準确知道剩餘電量的内置有機發光顯示器。

Eagle 600能發出如此大的光亮是因為它配備了一對發光二極管，3100毫安時的電池可以支持電池在最大強度下持續發光1個半小時。但是你也可以把亮度調低，或者改用閃光模式。微型的自然光顯示器會在同一時刻根據你選擇的模式顯示車燈可工作的時間。

Eagle 600是完全防水的，充電也很簡便，隻需要通過車燈背面封閉的USB接口就能完成。此外，車燈還配有一個可以從車把上速卸的底座，在夜晚修理的時候可以把車燈拆卸下來。Eagle 600 價格不菲，160美元的标價沒有美化的必要，然而，如果你在夜間有過因車燈沒電而涉險的經曆，那Eagle 600 或許真的物有所值。

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.
