Best Bike Turn Signals for Adult Tricycles
On a wide, upright trike, taking a hand off the bar to signal can unsettle the steering. A wireless signal lets you keep both hands on the grips.
Updated · 4 min read · 4 products evaluated

Hand signals are fine on a bike, but a trike changes the equation. With three wheels you cannot lean through a turn, so many riders keep both hands on wide cruiser bars, especially on a slope or a camber. A turn signal you trigger with a thumb makes your intention clear to drivers behind without loosening your grip.
This guide is only about signals. For headlights, tail lights, tape and vests, see the other guides in the visibility cluster. Here we compare the remote design, how each unit mounts on a trike's seat post, and how loud or visible each signal is.
Short answer
The Vcwtty light is our best overall pick, with yellow lane arrows projected on the road, a 120dB beep and a 3-button remote. The Teguangmei split unit is best if you want left and right lights spaced across a wide rear. The Meilan X5 adds automatic brake lighting, and the Lumos Ultra helmet suits riders who prefer signals on their head.

Best Overall1 of 4
Vcwtty Tail Light with Turn Signals and Lane Projection
Projected yellow arrows, a loud beep and a three-button remote that fits wide bars.
Best for
Riders wanting the most noticeable signal
Why we like it
The Vcwtty adds two things that help on a trike: yellow arrows projected on the pavement behind you, creating a visible boundary for drivers, and an audible beep up to 120dB when the signal runs. The 3-button remote handles left, right and mode, and it clips to round handlebars up to 1.8 inches (45 mm), which suits chunky cruiser grips.
The tail light strap secures to a cylindrical seat post up to 1.6 inches (40 mm). Against the Teguangmei it offers a single unit rather than a split pair, so your signals sit in one place. Runtime is up to 16 hours across five modes with USB-C charging and IP65 weatherproofing. It suits riders who want the loudest and most visible solution.

Best for Wide Rear Ends2 of 4
Teguangmei Split Turn Signal Tail Lights
Two separate units, one for each side, that can sit apart on a rear basket or rack.
Best for
Spacing signals across the width of the trike
Why we like it
This set comes with one left and one right light, and they can be mounted together on a seat post or taken apart and placed at opposite ends of the rear. On a trike with a wide basket, splitting them mimics a car's signals, so drivers read left and right clearly. A wireless remote switches left, right, steady red, steady yellow and fast flashing yellow.
The 120 lumen LEDs are rated visible at 50 to 100 meters, and the 600 mAh battery gives about 9 hours after a 3 hour charge. Compared with the Vcwtty it lacks the beep and projection, but the spacing is a genuine advantage. It suits riders with a wide rear basket who want signals at the edges.
Key specs
| Fit and mounting | Seat post together or split apart |
|---|---|
| Features | Split left and right units, 5 modes, 120 lumens |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Split left and right units

Best Auto Brake Light3 of 4
MEILAN X5 Wireless Turn Signal Tail Light
Adds automatic brake lighting and a ground warning line to a remote-controlled signal.
Best for
Riders who want brake and signal in one
Why we like it
The X5 has 30 LEDs and a brightness figure of 85 lumens, rated visible from about 150 feet. It adds automatic brake lighting that brightens when you slow, plus a ground warning line that projects a virtual lane. A four-button remote on the handlebar switches six lighting modes and signals, with a replaceable CR2032 coin cell inside.
The built-in 2000 mAh battery runs 5 to 10 hours in flash modes. Compared with the Vcwtty it is less bright in rated output and has no audible alert, and its reviewer base is thin, so treat it as a less proven option. It suits riders who value brake sensing in a single tail light.
Key specs
| Fit and mounting | Remote on handlebar, light on seat post |
|---|---|
| Features | 30 LEDs, auto brake light, ground warning line |
Specs can change between model years; confirm the exact version before buying.
Strengths
- Automatic brake light

- Replaceable remote battery
- Six lighting modes
Limitations

Best Helmet Option4 of 4
Lumos Ultra Helmet with Turn Signals
A CPSC-certified helmet with 360 degree lights and rear signals on a wireless remote.
Best for
Riders who already need a new helmet
Why we like it
The Lumos Ultra is a helmet first and a light second. It carries front and rear LEDs with TUV-certified 360 degree visibility, rear turn signals triggered with the included Remote Lite, and a CPSC safety certification. The app adjusts brightness and light modes, and USB-C charging gives up to 10 hours depending on mode.
An upright trike rider's head is at driver eye level, which makes helmet lights well placed. Compared with the seat-mounted options here, it signals from your head, so it does not show the trike's width. The separate Lumos Remote adds automatic brake lights. It suits riders replacing an old helmet who want signals without extra hardware.
Key specs
| Features | TUV 360 degree lights, rear turn signals, CPSC certified |

Specs can change between model years; confirm the exact version before buying.
Strengths
- Helmet and signals in one
- CPSC certified protection
- App adjustable modes
- USB-C charging
Limitations
- Signals come from the head, not the trike
- Brake lights need a separate remote
Consider it if
- Riders replacing a helmet
- Upright riding at driver eye level
Skip it if
- Riders who want signals fixed to the trike

How We Chose These Bike Turn Signals
- Remote usability
- We checked whether the remote clips to round bars and can be pressed with a thumb without letting go.
- Signal visibility
- Brightness, color, projection and audible cues were compared for how clearly a driver can read intent.
- Mounting on a trike
- Seat post diameter and the option to split lights across a wide rear were weighed heavily.
- Battery and weather
- We favored USB-C, stated runtime and IP ratings for trikes stored outdoors.
What to Look for in a Bike Turn Signal
Remote placement on wide bars
A remote that clips on the bar close to the grip can be pressed with your thumb without moving your hand. On wide cruiser bars the controller sits farther from your center, so a big, tactile button matters.
Check the maximum bar diameter and button layout. Three or four large buttons are easier than a tiny single one for older hands.
Signal that drivers actually read
Amber flashing is read as a turn signal, while red flashing reads as a brake or a warning. Projection and sound add to the message.
Look for a steady yellow or amber mode, and consider whether a loud beep suits your area.
Seat post and basket mounting
A silicone strap that fits a round seat post will not necessarily fit a rack or basket frame. Trike seat posts can be thicker than bike posts.
Measure the post and check the strap range. A split unit is easier to place on a rear basket.
Battery of both parts
Many systems have a light battery and a remote battery. If either dies, the signal stops.
Look for a replaceable coin cell in the remote and USB-C charging for the light, and check them weekly.
How to Choose
By Signal Style
| Situation | Our pick | Why |
|---|---|---|
| Loudest and most visible | Vcwtty Tail Light with Turn Signals | Lane projection and 120dB beep |
| Signals at the edges of a wide rear | Teguangmei Split Turn Signal Lights | Separate left and right units |
| Brake and signal in one | MEILAN X5 | Automatic brake light |
| Helmet and signals together | Lumos Ultra Helmet | CPSC certified with rear signals |
| Quiet neighborhood riding | Teguangmei Split Turn Signal Lights | Silent, clear yellow signals |
Seat Post Unit vs Helmet Signals
- Seat post unit
- The Vcwtty, Teguangmei and MEILAN mount to the trike, so the signal shows the machine's position and width.
- Helmet
- The Lumos Ultra puts signals at head height, where drivers look, but they do not show the trike's width.
Default to a trike-mounted unit and add a helmet only if you also need a new helmet.
For Older Riders and Stiff Hands Specifically
- Look for
- Large, separated buttons, a remote that clips near the grip, and an audible confirmation that the signal is running.
- In this comparison
- The Vcwtty's 3-button remote and 120dB beep give clear feedback without looking down.
When to Spend More
- Spend more if
- You ride on busy roads with fast traffic. The Vcwtty's projection and beep are worth the cost.
- Save if
- You ride quiet streets. The Teguangmei split unit gives clear signals without projection.
Frequently Asked Questions
Do I need turn signals on a trike?
Not legally in most places, but they help because trikes are wide and hand signals can unsettle the steering. A wireless signal keeps both hands on the grips.
Will the remote fit wide cruiser bars?
Check the maximum bar diameter. The Vcwtty remote fits round bars up to 45 mm, and most cruiser grips fall within that.
Are bike turn signals waterproof?
The Vcwtty is rated IP65, while others state general waterproofing. If your trike lives outdoors, prefer a stated IP rating.
Can I mount signals on a rear basket?
The Teguangmei's split design is made for this. Check that straps fit your basket frame and that cargo does not block the lights.
How long do remote batteries last?
Coin cell remotes last months. Keep a spare CR2032 and check the remote before every long ride.
Bottom Line
The Vcwtty is the best all-round signal for most adult trike riders. Choose the Teguangmei for a wide rear basket, and combine signals with a tail light and reflective gear for a full visibility setup.
