This t-shirt is all about light as it is just a lightbulb t-shirt.
On the shirt, you can see a big lightbulb and that makes this t-shirt perfect for when you feel dark or when you need a smart idea quickly.
Also, it is just a great looking t-shirt so there is no real other reason needed for you to wear this t-shirt.
And as it comes in many colors you could even choose to wear a different color every day of the week.
