The model 1820 steering taillight uses 18-SMD and 14-SMD lamp beads and is operated by a supplied wireless remote control, so the rider can signal turns and sound the horn without reaching for the handlebar-mounted light itself. The housing measures 9.4 x 3.2cm and is finished in black. A built-in 900mAh lithium battery is recharged through the included USB cable, which means the unit does not rely on disposable batteries. The package also contains a turn signal base, two silicone straps, and an instruction manual. This description is based on the stated product data only; no waterproof rating, runtime, brightness, or compatibility figures are given in the source.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB rechargeable bicycle turn signal with horn, 9.4 x 3.2cm, 900mAh, wireless remote 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\n\u003cp\u003eThe core construction details are the lamp bead types, the built-in battery, and the mounting hardware. These determine how the unit is powered and attached to the bike, and they are the main facts available for this model.\u003c\/p\u003e\n\u003ch3\u003eLamp Bead Types\u003c\/h3\u003e\n\u003cp\u003eThe turn signal uses 18-SMD and 14-SMD lamp bead types. SMD refers to surface-mounted LED components, and the two figures indicate different bead counts or groupings within the light unit. The source data does not state brightness in lumens, beam angle, or flash patterns, so those details cannot be confirmed. What can be confirmed is that the light is built around SMD LEDs and is intended as a rear steering taillight for indicating turns.\u003c\/p\u003e\n\u003ch3\u003eBattery and Charging\u003c\/h3\u003e\n\u003cp\u003eA built-in 900mAh lithium battery powers the unit, and charging is done through the supplied USB cable. This removes the need to buy and replace disposable batteries, which is a practical consideration for regular cyclists. The source data does not state charging time, runtime per charge, or battery lifespan. The 900mAh capacity is the only battery figure provided, and it should be treated as the stated capacity rather than a performance guarantee.\u003c\/p\u003e\n\u003ch3\u003eMounting Hardware\u003c\/h3\u003e\n\u003cp\u003eThe package includes a turn signal base and two silicone straps. Silicone straps are flexible and are used to secure the base to the bike, allowing the unit to be fitted without tools in many cases. The exact tube diameter range is not stated, so compatibility with a specific seatpost or frame tube cannot be confirmed from the source. The base is specific to this turn signal model.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB rechargeable bicycle turn signal with horn, 9.4 x 3.2cm, 900mAh, wireless remote 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\n\u003cp\u003eThe unit is intended for rear mounting on a bicycle, where it can indicate turns and sound a horn.

The remote control allows the rider to operate the indicators and horn without moving a hand far from the bars. The black housing and compact size suit a rear-facing position. No specific event certifications or professional standards are claimed in the source data.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor daily commuting, shopping trips, or leisure rides, the turn signal and horn functions address two common safety tasks: showing which way you intend to turn and giving an audible warning when needed. The USB-rechargeable battery means the unit can be topped up at home or at a desk using the supplied cable. The silicone straps allow fitting to the bike and removal for charging, depending on the setup.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB rechargeable bicycle turn signal with horn, 9.4 x 3.2cm, 900mAh, wireless remote 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\n\u003cp\u003eThe practical value of this product lies in combining two functions in one rear unit and using a rechargeable battery.

There are no stated maintenance requirements beyond charging and keeping the unit clean. The silicone straps are a wear item but are included in the pack. No waterproof rating is given, so it is reasonable to keep the unit protected from heavy rain and to avoid submerging it.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis model 1820 steering taillight is a reasonable choice for cyclists who want turn indication and a horn in a single rear-mounted unit with a wireless remote.

The package includes the turn signal, remote control, turn signal base, two silicone straps, USB cable, and instruction manual. Buyers who need confirmed waterproofing, specific runtime, or brightness figures should note that those details are not provided in the source data.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB rechargeable bicycle turn signal with horn, 9.4 x 3.2cm, 900mAh, wireless remote 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=\"Black USB rechargeable bicycle turn signal with horn, 9.4 x 3.2cm, 900mAh, wireless remote 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":"qydz45-fd","offers":[{"title":"Black","offer_id":64859751711097,"sku":"CJYD234077101AZ","price":16.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/1781\/0553\/files\/731a7819-54dd-47c7-9e14-c3f849af367f.webp?v=1791836506","url":"https:\/\/carovelle.com\/products\/usb-rechargeable-bicycle-turn-signal-with-horn-18-smd-14-smd-led-cycling-rear-light-9-4cm-x-3-2cm-built-in-900mah-battery-wireless-remote-black-for-bike-safety-and-commuting","provider":"CaroVelle","version":"1.0","type":"link"}
