No frills light kit which is really very very bright! The installation instructions given on RC Mart's page are helpful and it's a pretty easy job, just make sure you clean the inside of shell so that your tape sticks.
It's really also a good idea to use Bluetack to cover the LEDs if not the "stray" light from the ultra bright LEDs will light up the rest of the shell!
It comes with 4 blue light for the front so make sure your light bucket can take that or you'll have to think about what to do with the redundant lights. Would be nice if they can make a version with 4 fronts and 4 backs (red).
