USB Car Roof Starlight Projector — Ambient Night Light

The cheapest way to get a starlight headliner. It plugs into a USB port and projects points of light across the roof lining.

What you get

• USB powered — no wiring, no fuse tap. Plug it in and it works.
• Colour options — blue, red, or red and blue together.
• Voice control version — reacts to music and sound.

Worth knowing

Keep the projection on the roof lining and away from the windscreen and your own eyeline. Light bouncing off the glass at night is genuinely distracting, and that is the one way this stops being harmless fun.
