FAQ & Help Center
Custom LED signage

Your message. Your colors. Your car.

The FlexLED Display™ is a flexible full-color LED panel that curves to your rear window and shows whatever you want — custom text, RGB patterns, animations, even artwork you draw yourself — all controlled from your phone.


FlexLED Display flexible scrolling LED panel showing custom text in full color

A sticker says one thing forever. This says anything you want.


Decals fade, peel and commit you to one joke for three years. The FlexLED Display™ changes in seconds from your phone — a message for the car behind you, your shop name on a delivery run, or pure personality on a night drive.

Full-color RGB LEDs — bright enough for day or night
Bluetooth app control — text, patterns, drawings, animations
Flexible panel curves to fit rear windows and contoured glass
5V USB power with an inline on/off switch — no wiring
Sound familiar?

Why most car signage falls short


Decals are permanent and instantly dated

One message, stuck on your glass until you scrape it off. No way to change it for the season, the occasion or the mood.

Rigid LED signs won't sit flat on curved glass

A hard panel on a sloped rear window leaves gaps, rocks around and looks like an afterthought from behind.

Cheap displays mean single-color text and clunky remotes

One-color scrolling letters and a plastic remote you lose in a week — no patterns, no animations, no real customization.

Why it wins

Built to flex. Built to stand out.

Every feature aimed at one thing — total control over what the road sees.


1

Full-color RGB LED matrix

Ultra-bright full-color LEDs render text, icons, flags and artwork in vivid color — readable in daylight and impossible to miss after dark.

2

Bluetooth app control

Pair your phone and change the display instantly. Type custom text, pick a preset pattern, draw your own graphic or load an animation — no remote to lose.

3

Flexible panel design

The panel bends and curves, so it mounts flush against sloped rear windows, contoured glass and irregular surfaces where rigid signs simply won't sit.

4

Adjustable brightness and speed

Dial brightness up for bright daylight or down for night driving, and set scroll speed so your message reads cleanly at any distance.

5

Music and microphone modes

Let the panel react to audio in real time. The display pulses and animates with the beat — a full light show synced to whatever is playing.

6

Plug-and-play 5V USB power

Runs off any standard USB source with an inline on/off switch on the cable. Energy-efficient, no wiring into your vehicle's electrical system, no tools.

Six ways to display

Text, patterns, drawings, animation.

Every mode lives in the app. Switch between them in seconds, from the driver's seat or the sidewalk.

Your phone, your panel

Change the message in seconds.


Pair once over Bluetooth and the whole display lives in your pocket. Swap text, pull up a pattern, adjust brightness or fire off a drawing you made on the spot — no remote, no buttons, no reaching behind the seat.

Curves to fit

5V USB power

Energy efficient

Low power draw keeps it running without straining your setup

FlexLED Display panel with USB power cable and inline switch
Five sizes

Measure first. Then pick your size.

These panels run from palm-sized to over four feet wide. Bigger is not better here — match the panel to the surface you're actually mounting on.


Size Width × Height Best for
S 6.81 × 2.76 in (17.3 × 7.0 cm) Dashboard, small side window, desk or shelf
M 13.70 × 4.25 in (34.8 × 10.8 cm) Dash banner, side window, interior messaging
L 23.43 × 4.72 in (59.5 × 12.0 cm) Partial rear window on cars — the most popular pick
XL 35.35 × 7.56 in (89.8 × 19.2 cm) Full rear window on most sedans, SUVs and hatchbacks
2XL 52.36 × 7.56 in (133.0 × 19.2 cm) Too wide for most cars — vans, box trucks, storefronts and garage walls

How to measure in 30 seconds

Run a tape measure across the flat, unobstructed span of the glass — not the full window frame, and not including the curve at the edges. Pick the panel that is narrower than that number. For reference, rear glass on most sedans measures roughly 35–45 in at its widest point, which puts XL at the upper limit for a car and 2XL out of range.

FAQ

Questions answered.


Everything runs through the free companion app over Bluetooth. Type custom text, choose from the built-in pattern libraries, draw your own graphic pixel by pixel, or load an animation — then adjust brightness, speed and color from the same screen. Changes appear on the panel instantly.
Measure your glass before you choose — that one step prevents almost every sizing mistake. S and M are interior sizes for dashboards and side windows. L is the most popular pick for cars and sits across part of the rear window. XL fills the rear glass on most sedans, SUVs and hatchbacks. 2XL is over four feet wide, which is wider than the rear window on most cars — it's built for vans, box trucks, storefronts and garage walls, so don't pick it just because it's the largest option.
That's exactly what the flexible panel is built for. Unlike rigid LED signs that leave gaps on sloped glass, this one bends to follow the contour of the surface so it sits flush and looks integrated rather than propped up.
It runs on 5V USB — plug it into a USB port, a USB car adapter or a power bank. The cable has an inline on/off switch so you can shut the display down without unplugging it, and the LEDs are energy-efficient enough that they won't strain your setup.
Yes. The high-brightness RGB LEDs stay legible in daylight, and the app lets you dial brightness up or down so the display isn't overpowering at night. Scroll speed is adjustable too, so longer messages stay readable from a distance.
It does. Music and microphone modes let the panel respond to audio in real time, pulsing and animating with the beat. It turns the display into a live visualizer — a favorite feature at meets, shows and shop setups.
Rules on illuminated displays, window obstruction and light color vary by state and municipality — some restrict red or blue lighting visible from the rear, or displays that obstruct the driver's view. Check your local regulations before mounting, and consider off-road, show and stationary use where restrictions apply.
