Last month we featured the iblazr, an external LED flash for mobile devices (it’s on Kickstarter now if you want to get one). If you have an iPhone 4 or later and you want a more versatile flash, get Rift Labs’ The Kick.
Most modern smartphones have a built-in LED camera flash. But if you think that your phone’s flash isn’t bright enough to properly document your party nights, dramatic Instagram pics or Bigfoot sightings, keep an eye out for the iblazr.
If you weren’t aware of this, you can make your iPhone’s LED flash work as a notification light, so that you never miss any notifications (Settings-> General-> Accessibility-> LED Flash for Alerts). There’s one problem though.
