Teguangmei Bike Tail Light with Projection 2-in-1 Rechargeable Rear Light Kit, 150 Lumens, Remote Turn Signals

Teguangmei's 2PCS Bike Tail Light with Projection Turn Signals is a rechargeable, IPX4 waterproof rear light kit that projects bright left/right arrows and offers five remote-controlled modes for safer night riding.

These compact taillights combine high-visibility red LEDs and yellow directional projection to warn drivers and pedestrians of your movements. The set includes two detachable lights plus a wireless remote, a multiport USB-C cable, adjustable silicone mounts and simple pairing instructions. With 150 lumens and multiple mounting options, the kit adapts to bikes, e-bikes, scooters and small motorcycles.

How does the arrow projection improve visibility during night rides?

The built-in arrow projection casts a clear left or right indicator onto the road surface behind you, making your intended direction obvious to following traffic. This layered signaling—steady taillight plus projected arrow—helps reduce confusion in low-light conditions without requiring riders to over-gesture.

• Bright yellow arrow projection for clear directional cues
• Red SMD taillight for continuous rear visibility
• Projection works on asphalt and other firm surfaces
• Designed to attract attention from drivers and pedestrians

What lighting and control modes are available, and how do they help?

The remote-controlled system switches between five practical modes to match riding needs: steady taillight, taillight plus static arrow, taillight plus flashing arrow, left-turn sequence with horn, and right-turn sequence with horn. These options let you choose a low-power steady mode for long rides or an emphatic flashing/projection mode when you need extra attention.

• Five modes accessible via compact wireless remote
• Turn signal mode triggers both projection and audible horn
• Flashing and steady options for visibility vs. battery savings
• Remote range suitable for handlebar mounting while riding

Can I mount the lights in different positions on my bike?

Yes—each light is detachable so you can install both together on the seatpost or mount them separately on left and right stays or wheel brackets. Flexible silicone straps and rubber rings make tool-free installation quick and adjustable to different tube diameters.

• Combined seatpost installation for a single rear unit
• Separated left/right mounting for clearer lateral signaling
• Silicone straps and rubber rings fit varied frame sizes
• Works on bicycles, e-bikes, scooters and small motorcycles

What about battery life, charging, and weather resistance?

Each taillight uses a rechargeable 750 mAh battery, and both lights plus the remote charge through USB-C using the included 4-in-1 cable. Rated IPX4, the lights withstand splashes and rain, making them suitable for most wet-weather commutes—just avoid full submersion.

• 750 mAh rechargeable battery per rear light
• Included USB-C multiport cable charges multiple devices simultaneously
• IPX4 splash-resistant construction for rainy rides
• 150 lumens total brightness for nighttime visibility

Who is this for?

This Teguangmei kit is aimed at commuters, e-bike riders and urban cyclists who want a compact, easy-to-fit signaling solution that increases rear visibility and communicates turns more clearly to traffic. It also suits scooter owners and riders who need a rechargeable, weather-resistant light set with remote control and multiple mounting options.
