The set includes a remote control that operates both functions, so the rider can keep both hands on the bars while indicating or sounding the horn. The unit is listed as the 1820 steering taillight and uses 18-SMD and 14-SMD lamp beads for the turn signal display. Power comes from a built-in 900mA lithium battery that recharges over USB, so there is no need to buy disposable batteries. At 9.4 x 3.2cm, it is a compact unit intended for fitting to a bike with the supplied base and two silicone straps. The black finish suits most bike frames and seat posts. It is aimed at commuting, group rides and general road cycling where a visible rear indicator and an audible warning are useful. The package also includes a USB cable and an instruction manual.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB charging bicycle turn signal with horn, 9.4 x 3.2cm, black, with remote control and silicone straps\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/3926\/2025-10-18\/original-image\/731a7819-54dd-47c7-9e14-c3f849af367f.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe construction centres on a rear-facing light unit, a remote control and a strap-based mounting system. This section covers the lamp beads, the rechargeable battery and the physical size of the unit, all based on the stated product information.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe turn signal uses 18-SMD and 14-SMD lamp beads as its light source, giving two lamp bead types within the unit. A built-in 900mA lithium battery powers the turn signal and horn functions and is recharged through the supplied USB cable. The turn signal base and two silicone straps are included for mounting the unit to the bike. The remote control is a separate part of the set and is used to operate the turn signal and horn. No waterproof rating, impact rating or housing material is stated in the source information, so those details are not confirmed here.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe product measures 9.4 x 3.2cm, making it a compact rear-mounted unit. That size is intended to fit onto a bike using the supplied base and silicone straps rather than requiring a fixed bracket. The light is supplied in black. Before fitting, the unit should be charged via the USB cable. The silicone straps are the stated fixing method, and the instruction manual covers the setup. Because the source lists only the 9.4 x 3.2cm measurement, no further size figures are given.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB charging bicycle turn signal with horn, 9.4 x 3.2cm, black, with remote control and silicone straps\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/3926\/2025-10-18\/original-image\/b1429490-37a9-48d7-860d-ed2c356e4a36.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis light set suits riders who want a rear turn signal and a horn operated from one remote. The following points cover event or group use and everyday home or commuting use, using only the stated functions and supplied parts.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eFor group rides and organised cycling events, a rear turn signal can help show direction changes to riders behind, while the horn gives an audible signal. The handlebar-mounted remote allows both functions to be operated without moving the hands from the bars. The 18-SMD and 14-SMD lamp beads form the turn signal display, and the 900mA lithium battery keeps the unit rechargeable between rides via USB. The black unit and strap mounting suit temporary or transferable fitting between bikes.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor daily commuting or leisure cycling, the same turn signal and horn functions can be used on familiar routes. The rear-mounted steering taillight shows turn direction, and the horn provides a warning sound when needed. Charging at home is done with the USB cable, and the unit can be removed or refitted using the silicone straps and base. Because no runtime or charge time is stated, charging should be planned according to use. The instruction manual should be followed for setup and operation.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB charging bicycle turn signal with horn, 9.4 x 3.2cm, black, with remote control and silicone straps\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/3926\/2025-10-18\/original-image\/bf482f06-272a-4ffe-8d2b-59deb722bc22.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe practical value of this set comes from combining a turn signal, a taillight function and a horn in one rechargeable unit. This section covers reuse and low maintenance and the main reasons to choose this product, based on the listed contents and specifications.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eThe built-in 900mA lithium battery is rechargeable over USB, so the unit does not depend on disposable batteries. The two silicone straps and the turn signal base are the stated mounting parts and can be reused when moving the light between bikes. The remote control is part of the set, so no separate control unit is required. No battery lifespan, charge cycle count or service interval is given in the source, so maintenance should be limited to charging via USB, checking the straps and following the instruction manual.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eThis product is suited to riders who want a rear turn signal with a horn and a handlebar remote in a single set. The 18-SMD and 14-SMD lamp beads give the turn signal display, while the 900mA lithium battery makes the unit USB-rechargeable. At 9.4 x 3.2cm, it is a compact black unit that fits with the supplied base and silicone straps. The package includes the turn signal, remote control, turn signal base, two silicone straps, USB cable and instruction manual. Where waterproofing, runtime and charge time are not stated, those details remain unconfirmed.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB charging bicycle turn signal with horn, 9.4 x 3.2cm, black, with remote control and silicone straps\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/3926\/2025-10-18\/original-image\/c51d2f4c-80fb-4922-9953-95e875a83bae.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB charging bicycle turn signal with horn, 9.4 x 3.2cm, black, with remote control and silicone straps\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/3926\/2025-10-18\/original-image\/e15baf60-7fd9-473e-bdd6-03e3c8aea8ee_12e7f64c-fe70-4262-b669-aaa40814fb29.webp\"\u003e\u003c\/div\u003e","brand":"u9cmuw-dx","offers":[{"title":"Black","offer_id":58083168125308,"sku":"CJYD234077101AZ","price":17.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/1685\/3628\/files\/731a7819-54dd-47c7-9e14-c3f849af367f.webp?v=1793339882","url":"https:\/\/havenmere.co.uk\/products\/usb-charging-bicycle-turn-signal-with-horn-18-smd-14-smd-led-steering-taillight-9-4-x-3-2cm-built-in-900ma-lithium-battery-remote-control-bike-indicator-light-for-cycling-safety-black","provider":"Havenmere.co.uk","version":"1.0","type":"link"}
