Lepro ポータブルLED懐中電灯（グリーン、高ルーメン、防水、単4電池付属）

The 4.2-inch body is just right for my glove box, and the green casing makes it easy to spot in the dark. Even after a rainy walk, the waterproof seal held up perfectly, and it takes those three AAAs without any fuss.

Took it camping last weekend and the 4.2-inch frame disappeared into my jeans pocket between hikes. The waterproof casing handled a sudden downpour without a flicker, and the included AAA batteries meant I was lit up from the first click, no hunting for spares in the dark.

Pocket-sized and featherlight at 128g, so it disappears into a jacket without dragging the seam down. The green finish looks sharp, and having the AAA batteries included meant it worked the second I twisted it on.
