Questions
Will it fit my car?
It sticks to the flat inside panel near the bottom of the door, so it works on most cars, trucks and SUVs. If your door has a flat spot about the size of a coaster down low, you're good.
Do I need tools or wiring?
No. It's wireless with an adhesive pad. Wipe the spot clean, peel, press and hold for a few seconds. That's the whole install.
How does it turn on?
It turns on by itself when you open the door and switches off when you close it, so you never have to touch it.
How do I charge it?
Pop it off the door, charge it with the included cable, and stick it back on. The battery details are listed in the product description.
Can I see it during the day?
It's made for dusk and night. Like any projector, it's faint in bright sunlight, and it looks amazing once it gets dark.
Can I get a different racer on each door?
Yes. Pick the 2 or 4-door bundle and choose a racer for each door. Mix them or match them, it's up to you.
How fast does it ship?
Orders are processed within 1–3 business days, and you'll get a tracking number by email the moment it ships. The delivery estimate above the buy button shows when yours should arrive.
