Teguangmei Bike Tail Light Kit, 4-in-1 USB Rechargeable Rear Lights with Projection Turn Signals and Remote

Teguangmei 4PCS Bike Tail Light with Projection Turn Signals is a USB-rechargeable, remote-controlled rear lighting kit that projects directional arrows and offers five modes to increase nighttime visibility and communicate turns.

Riding after dark or in poor weather is safer when other road users clearly see your position and intentions. This kit combines ultra-bright red taillights and yellow arrow projections with a compact wireless remote so you can signal left or right without taking a hand off the bars. The lights are detachable for flexible mounting on seat posts, racks, wheel brackets or scooters and are rated IPX4 for splash resistance.

How do the projection turn signals improve my visibility?

The lights project bright directional arrows on the road behind you while the red taillights remain visible to following traffic. That second layer of visual information helps drivers and pedestrians quickly identify your intended direction, especially in low-light conditions.

• Bright yellow arrow projection combined with red taillight for contrast
• 150 lumens total output from multiple SMD LEDs
• Directional cue reduces rider ambiguity to motorists and pedestrians

What lighting modes are available and how do I control them?

The kit supports five distinct modes selectable via the included wireless remote: steady taillight, taillight plus steady arrow projection, taillight with flashing arrow, left-turn signal with left arrow and horn, and right-turn signal with right arrow and horn. Mode switching is quick so you can adapt to changing traffic situations without fumbling for settings.

• Remote-controlled selection of five modes
• Turn modes include audible horn signal for extra attention
• Remote pairs easily with lights; re-pairing steps provided if needed

How easy is installation and charging for daily use?

Installation requires no tools: silicone straps and rubber rings allow secure attachment to seat posts, handlebars, wheel brackets or other frame points. Rechargeable batteries power both lights and remote; a 4-in-1 USB cable charges multiple units at once for convenient turnaround between rides.

• Tool-free silicone mount straps and rubber rings included
• 750mAh internal battery per rear light with USB charging
• 4-in-1 USB cable charges lights and remote together

Who is this for? Cyclists, e-bike riders, scooter commuters and anyone who needs a compact, flexible signaling system for low-light riding will benefit. The detachable design suits riders who want to move lights between bikes or mount them on trailers and scooters, while remote control keeps signaling intuitive and safe during busy commutes.
