Grundig Heartbeat-Style LED Rear Light Bar for Tesla Model Y – Brake & Turn Signal - 2020-2024 Model Y

I. Product Overview A Model Y's tail lights are compact, and in dense traffic — at night or in the rain — a brake input is easy to miss. The Grundig Heartbeat-Style LED Rear Light Bar adds a second, wider band of light across the rear: a heartbeat-pattern LED bar that lights in a running pulse instead of one solid block, fires with the brake lights, and stays dark the rest of the time. It connects to the factory plug, so nothing is cut, spliced, or permanently changed on the car. The ABS + PC housing is sealed for weather, and an onboard MCU chip keeps the bar in step with the signals the car is already sending. II. Key Features Heartbeat LED Pattern. The segments light in a heartbeat-style pulse that travels along the bar, giving the rear of the car a look the factory tail lights don't have. Brighter, Easier to See. High-output LED beads throw a wider band of red than the factory brake lamps alone, so a brake input is easier to notice in traffic. Syncs with the Car. The bar follows the signals the car is already sending, so it lights on its own — there is nothing to switch on or adjust. Plugs In, Nothing Cut. Mates with the factory connector — no wire cutting, no splicing, and nothing on the car is permanently changed. III. Compatibility Select the variant that matches your model and model year.

Important Notes Professional installation is recommended. The bar plugs into the factory connector, so no wiring modifications are needed. After installation, test every mode: left and right turn signals, hazard flashers, brake lights, and headlights on. Keep the lens clean. Road film, salt, and mud reduce how much light the bar throws. Rules about additional rear lighting vary by state and country. Check your local requirements before installing.
