No Twinkle Lights
Many schools consider plug-in twinkle lights a fire hazard, but they can add a very essential ambiance to your room. Bright overhead LEDs are not our favorite when it comes to late night reading or hosting friends in your dorm. But you know what can help you out and not count as contraband? Battery-powered lights.
