4-PIN Turn Brake Lamp & Inner Tail Light for Tesla Model 3 & Model Y
Restore damaged or malfunctioning rear lighting with vehicle-specific 4-pin replacement assemblies for the body-mounted turn/brake lamp and trunk-mounted inner tail light. Choose the exact lamp type, side and connector configuration required by your Tesla.
Dedicated 4-PIN Connection
Designed specifically for compatible Tesla rear-light assemblies using a four-pin electrical connector. A 3-pin vehicle requires the separate 3-pin version.
OE-Specific Replacement
Current part-number references are supplied for each left and right lamp assembly so fitment can be verified against the original component before ordering.
LED Rear Lighting
Integrated LED illumination restores the visual continuity of the rear lamp assembly while maintaining the intended rear signaling and vehicle-presence lighting functions.
Replace Only the Rear Lamp Section You Need
The outer rear lamp mounts to the body / rear quarter area and contains the corresponding turn and brake lighting functions for the selected side.
The inner lamp mounts on the trunk-lid section and visually continues the rear light signature toward the center of the vehicle.
Choose the combined configuration when both the outer and inner lamp assemblies on the selected vehicle side need replacement.
Select a single side for localized repair or a pair when both sides require replacement.
Current manufacturer materials identify a durable ABS lamp housing designed for normal exterior automotive exposure.
4-PIN Must Be Confirmed Before Ordering
Do not order by model year alone. Remove or inspect the original lamp connector and confirm that it has 4 pins.
If your original lamp uses a 3-pin connector, this version is not the correct replacement.
Match the OE Number to the Exact Lamp Position
Older description content on the source and TESKAY pages still contains 1077402-00-B, but the current 4-pin product selection table specifically identifies 1502086 / 1502087 / 1502088 / 1502089. Confirm the number printed on your original lamp whenever possible.
Confirm Connector & OE Number Before Installation
Determine whether you need the body-mounted Turn Brake Lamp, the trunk-mounted Inner Tail Light, or both assemblies.
Select the side as viewed from the driver's seating direction: left side or right side of the vehicle.
Inspect the electrical connector on the original lamp. It must match the four-pin specification for this product.
Compare the original lamp label with the current OE references listed above before removing the assembly.
Access the retaining hardware from the trunk or rear-body trim area, disconnect the original harness, remove the damaged lamp and install the matching replacement.
Test the relevant tail, turn, brake and other applicable rear-light functions before reinstalling all trunk trim.
Current manufacturer instructions describe direct replacement using the matching factory-style connector. Cutting or splicing the original vehicle wiring is not specified as required.
The current TESKAY selector extends Model Y compatibility through 2025.03, while the current Tesery 4-PIN technical header still lists Model Y 2020–2024. For early-2025 vehicles, confirm the original 4-pin connector and OE part number before ordering.

Quick Answers
Which exact configuration is selected in the supplied link? +
Variant 47054752186600 currently resolves to Inner Tail Light & Turn Brake Lamp with Position Left. The manufacturing-plant field still requires selection.
What comes with Inner Tail Light & Turn Brake Lamp / Left? +
It represents the two corresponding left-side lamp sections: the left outer Turn Brake Lamp and the left trunk-mounted Inner Tail Light.
What does Pair mean? +
Pair means both left and right for the selected lamp type. If the combined Inner Tail Light & Turn Brake Lamp type is selected together with Pair, it corresponds to the left and right outer lamps plus the left and right inner lamps.
Does this product fit a 3-PIN Tesla tail light? +
No. This listing is specifically for 4-pin lamp connectors. A separate 3-pin version must be used for vehicles equipped with a 3-pin original connector.
Does it fit Model 3 Highland? +
No. The current product covers the pre-Highland Model 3 rear-light generation. Highland uses a different rear-light design.
Does it fit Model Y Juniper? +
No. Model Y Juniper uses a substantially redesigned rear lighting system and is not part of this 4-pin legacy Model Y listing.
Why is Model Y 2025.03 listed on TESKAY if Tesery says 2020–2024? +
The current TESKAY selector extends the legacy Model Y option through 2025.03, while the current Tesery technical header remains 2020–2024. For an early-2025 Model Y, verify the original 4-pin connector and OE lamp number before ordering.
Which OE numbers should I check? +
Turn Brake Lamp: left 1502086-00-D, right 1502087-00-D. Inner Tail Light: left 1502088-00-B, right 1502089-00-B.
Is 1077402-00-B the correct OE number for this product? +
Older source-page content still displays 1077402-00-B, but the current 4-PIN selection table specifically lists 1502086-00-D, 1502087-00-D, 1502088-00-B and 1502089-00-B. Those current numbers should be used for this listing's fitment verification.
Do I need to choose Fremont/Texas or Shanghai/Berlin? +
The Tesery source still asks customers to select the manufacturing plant. The current TESKAY selector does not expose a separate plant field, so confirming the 4-pin connector and OE number is especially important.
Is this a complete aftermarket taillight redesign? +
No. This product is intended as a replacement lamp assembly for the corresponding original rear-light positions rather than a full four-lamp custom taillight conversion kit.
Does installation require cutting or splicing wires? +
No. Current manufacturer information describes direct plug-and-play integration with the compatible original vehicle connector.
Do I need vehicle coding after replacement? +
No coding procedure is currently listed as part of the standard replacement installation. Always test all lamp functions before completing trim reassembly.
Is a specific IP rating published? +
The manufacturer describes the ABS housing as weather-resistant, but no verified IP65 or IP67 rating is published for this current listing.
Are wattage or overall dimensions published? +
No verified wattage, lumen output or overall physical dimensions are currently published, so this description does not invent those specifications.
