The app is very straightforward and may not have voice commands or voice assistant controls. **Q: Can you link two screens into one larger continuous panel?** A: You could use the "grafitti" feature of the app to make left/right or upper/lower images, put each image to the panel desired. With that you could make a screen of any size. But... probably only if you set their displays to "static" (no scrolling, no phaser fire, etc). **Q: Will the message appear as soon as power is applied, or do you have to press a button to make the message appear?** A: You can save several messages to use. The currently selected menu will load & appear as soon as the power is turned on. You can change to different messages on your phone. Remember, the message that is on the screen when you turn it off will be the message that shows when you turn it back on. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value *by J***A on December 19, 2025* Great value for the price. I like the brightness of the light and color. The sign quality and easy use of the app. No problem with installing. ### ⭐⭐⭐⭐⭐ Doopeee *by C***S on January 17, 2026* Love this, nice and bright with many things you can do and edits through the app!! ### ⭐⭐⭐⭐⭐ Not a bad deal at all *by F***R on December 20, 2022* TLDR: works as advertised, great seller Want to give the seller mad props, for one. They are super-concerned that you're satisified with your purchase, and I'm good with that. That being said, I'm quite satisfied. The thing works more or less straight out of the box. Download the app, do the bluetooth thing, and zip-zap-zowie, you're up and running. The tape that comes with it for mounting is sort of so-so, and it might be that my particular installation has something to do with it, so no points off. Your mileage will vary. I attached it to a stiff piece of cardboard, and the whole thing fits nicely in my back window. The USB adapter and cables that come with it are more than adequate to reach from a front-seat power socket to the rear, unless you're driving a bus or something. I also like the inline switch, if you need to go dark quickly. My particular installation, I power it from a USB battery-brick. The app is pretty straightforward and easy to use. There's a bunch of admittedly cute built-in animations, and a mechanism to create your own. I'd like to see some improvments to the app - when building animations, it would be nice to have the option to use the previous 'frame' as the starting point for the next. Also, some cut-and-paste functionaility. But it's a work in progress, so I'll hang out to see what comes down the pipe. ## Frequently Bought Together - KJOY Programmable Huge Bright LED Signs, 27''x5'' USB 5V, Bluetooth App Control Custom Text Pattern Animation, Scrolling, Flexible LED Display for Car Store Party Bar Hotel - Nebudo Compatible with Lyft & Uber (2-Pack) Tips Rating Appreciated Rideshare Accessories – 7” x 5” – Interior Acrylic Headrest Sign - Rate Me Tip No Smoking for 5 Star Rides for Ride-share - OHLPRO Multi Car Retractable Backseat 3 in 1 Car Charging Station Box Compatible with All Phones | iPhone | Samsung | Uber Taxi Lyft Turo Ride Share Customer Charging Dock Attach to Headrest --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/486884784-led-car-sign](https://www.desertcart.hk/products/486884784-led-car-sign) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-30*
