I have the WozMods balloon in conjunction with the tree eye lights (same light controller). The one I have has no sounds. I probably would not like it with the sounds. It does light up that area better too, as mentioned previously. It is a good little mod to have for the effect.

Mezelmods has the lighted winkie also, but a lot of people report that those break easy. Mine from Mezel has not broke in 400+ plays with flipper strength set as the default from the factory and play field at 6.5 degrees. Mezel is working on a design change for those (last I saw from a mezel post on pinside). For now, I would go with the IndyPin version as that gets better reviews currently.

Just so you know ... the ones from WOZMods are not individual mini LEDs. You drill some small holes in the tree eyes and fish a LED on a wire up into the tree behind the eyes. You then tie wrap the wires for the LEDs in the trees so that they do not fall back down. I like it, it is "ok", but it would have been better with individual mini LEDs in the eyes. That would be much harder to do and I would probably pay someone to do that. Like what someone did with the witch replacement mod that sillyoldelf made. If you want to spruce up the witch see the pic gallery in this:

I bought one, but have not installed it yet.
