Drive kind.
Say it with light.
A clear THANK YOU for the driver behind you, exactly when you want to say it.
Install. Press. Thank.
Many THANK YOU signs turn a simple gesture into something unnecessarily complicated. Programmable displays, easily misplaced remote controls, smartphone interaction while driving, and batteries exposed to extreme heat behind the rear window all introduce inconvenience and potential safety risks.
We believe saying THANK YOU on the road should be simple, immediate, and effortless. That's why we created BettaSign.
One Button. Instant Feedback.
The softly illuminated wired button is easy to find, even at night. Secure it in a convenient spot inside your car using the supplied 3M double-sided adhesive tape.
Press once to light up THANK YOU for 3 seconds. The button brightens to confirm activation, then returns to its soft glow as the sign switches off automatically.
Easy to Mount. Easy to Adjust.
BettaSign attaches securely using suction cups. Its reversible mounting brackets allow the suction cups to face either side of the sign, offering more installation options. The flexible brackets can also be bent to adjust the viewing angle.


Easy to Connect. Ready to Go.
Connect BettaSign to your car's power supply, and it's ready to use.
Why BettaSign?
A simpler way to say THANK YOU, without unnecessary controls or maintenance.
