FSD Real-Time Blue LED Autopilot Signal for Model Y Juniper

More than just a light—it’s a real-time communication bridge between your car’s Autopilot state and the outside world: clear, safe, and precise.
Not just an accessory, but a core component enhancing safety, communication, and the driving experience—precisely engineered for your Tesla.
The module reads core CAN bus data in real-time, synchronizing the LED instantly when FSD activates for true zero-latency performance.
Utilizes an OEM-grade plug & play connector. No wire cutting or modification required, ensuring your factory warranty remains fully intact.
In the silent EV era, ambiguity creates risk. Our Smart Blue LED clearly communicates “I am driving autonomously” to everyone on the road.
Engineered using 3D scans of the original interior, it seamlessly integrates with your car’s design, becoming completely invisible when deactivated.
A non-destructive installation with an OEM-level precise fit that looks like an original factory component.
This is not a generic accessory, but a precisely modeled component. It perfectly matches Tesla interior contours with no gaps or misalignment.
Follow our detailed video to complete the installation with ease. Most users finish within an hour.
Your questions, answered.

Yes. It is designed for DIY installation. The kit includes a detailed video guide and all necessary tools. Most users complete it in under an hour.

Once your return request is approved, we will send you detailed return instructions, including the shipping address and packing guidelines.
Ship the Item Back:
Please ship the item back according to the instructions provided. Please note that items sent back to us without first requesting a return will not be accepted.
6. Non-Returnable Items
Due to their nature, certain types of items are not eligible for return:
Customized Products: For example, steering wheels and wheels that are explicitly marked as custom products cannot be returned for non-quality-related issues.
Specific Items: This includes gift cards, hazardous materials, or flammable liquids/gases.
If you have any questions about the eligibility of a specific item, please contact us before making a purchase.
7. Refunds & Exchanges

Once we receive and inspect your returned item, we will notify you and inform you if the refund has been approved. Approved refunds will be processed automatically to your original payment method within 1-5 business days. The final credit posting time depends on your bank or credit card company.
Exchanges:
For the fastest way to ensure you get what you want, we recommend that you return the item you have, and once the return is accepted, make a separate purchase for the new item.
8. Refunds for Orders Placed by Mistake:
Please be advised that if an order is placed due to an accidental click and is subsequently refunded, a 5% transaction fee will be deducted from the refund amount. This fee is charged by the payment processor, not by TESERY. Therefore, the refunded amount will be less than the original payment.
To avoid any inconvenience or loss, we kindly ask you to double-check your order before completing the purchase. Mistakenly placed orders may incur this additional fee, so we encourage careful attention during checkout.
Your satisfaction is of the utmost importance to us. If you have any questions, please do not hesitate to contact us. Thank you for choosing to shop with TESERY!

- Supporting photos and/or short videos demonstrating the problem
Please note:
Failure to provide the required information may prevent us from accurately diagnosing the issue and may result in delays or inability to process returns, refunds, or replacements.
