This device consists of a HUD and a worn object. When you click the HUD, a lightbulb particle appears above your head.

To create your own, simply put the [WaS-K]-[BIO:SE-SX] I Got It! - HUD script in a HUD and the [WaS-K]-[BIO:SE-SX] I Got It! - Nose script, in a primitive and then attach that primitive to your nose (newer viewers also support Add, so you can have multiple objects on the same attachment point).

The product is also available on the marketplace.

Except the mentioned authors, some thanks should go to Jopsy Pendragon from the particle laboratory since the lightbulb emission is based on the smoke particle template.
