H7 bulb storage case

 While replacing a bulb in my car, I ran into a familiar problem: spare H7 bulbs from a two-pack always end up loose somewhere in the car, where they can easily get damaged.

At the same time, the spare bulb should be kept in the car so it’s readily available in case of an emergency. Unfortunately, the original packaging is not suitable for long-term storage once opened.

To solve this, I designed a simple and compact storage box for an H7 bulb.
