Standard keyboard has 3 main light emitting diode (LED) which are used to monitor if you activate the ‘Num Lock’, ‘Caps Lock’ and ‘Scroll Lock’ function. If you feel like changing these LEDs function into something else, you can use it as a network traffic network indicator. Talking about the good old Windows 98 dial-up tray icon days =)

A small tool called Network Lights will allows you to use your keyboard LED as network traffic indicator. When there is download or upload network activity, Network Lights will make the ‘Num Lock’ and ‘Scroll Lock’ LEDs blinking. You can impress your friends with your new cool network activity indicator LEDs. Network Lights also works on laptop’s keyboard LEDs (tested on my friend's Compaq Presario v5000).

Network Lights is small, version 1.1 is less than 100KB. When you run Network Lights, it will sit on the system tray. The program uses around 1.3MB of memory. Network Light is freeware and available for Microsoft Windows operating system.
