This is a Rubber Stamp icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
This looks like a light bulb on top of a horizontal rectangle. The horizontal rectangle is rising to meet the light bulb in the center. There's a much smaller rectangle along the bottom of the big rectangle.
