I had this idea while eating "inspirationBell" (Seriously, whenever I eat Taco Bell I get into philosophical/inventive convos or thoughts...)

2 ideas I got-

3 seperate LED clusters, (in shape of triangle,square,circle) controlled by 3 seperate spikes.

2 LEDs, allowing for 4 different "commands".
(Both off, one on one off, one off one on, both on)

Not sure if they make these, but a LED, where if given regular polarity (Set the Spike forward) one color, and if given reverse polarity, it is a different color. (Set relay reverse.) No color = off, or circle, for example.
