If you want to build larger laser swamp and avoid shadows, you may need lasers to shine towards each other.Application：  Laser Swamp: To make a better effects of laser swamp, you’d better use the module in pairs. The modules should aim at each other in pairs, so that the player moving through the laser swamp will not block the light and there no “shade” side of the laser swamp.

And please note that, the modules have to aiming at each other at the same hight，and the lines from each modules must be overlapped at each other to make a single surface.Accessories: Accessories are shipped according to your option.
