I was inspired by this thread to order up a set of these to install on my IMDN.
The black drop target from the factory are hard to notice on IMDN due to the sharp angle that they are at vs. the players view. You basically don't see the target faces at all unless you view the game from the left side. So I wanted to spruce things up a bit by using these transparent targets and some additional LED lighting to make the targets pop a bit.
These targets work well, no strange bricking or other noticeable differences in play behaviour vs. the stock black ones. If anything I'd say these are more durable feeling in the hand as well. They are a "milky white" transparent, not perfectly clear, which is fine for my scenario.
...and you thought I was kidding!
I used a 3 segment 5v LED strip directly behind the targets to light them up, connected to the nearby GI bulb. They go on and off with the GI as well which is nice for Fear of the Dark mode and others. They are bit bright at the moment so may experiment with other LED colours and placement in the future to refine the look a bit.
Overall these are fantastic and I wouldn't hesitate to recommend them!
