If your 2023+ Tesla Model 3’s left rear fascia lamp is dim, flickering, or completely out—whether from a broken bulb, water damage, or a cracked housing—this CFN rear fascia lamp assembly is the reliable replacement. As a CFN branded part (not Tesla OEM), it’s engineered to match the 2023+ Model 3’s left rear body design, light output, and electrical specs, ensuring both safety compliance and a factory-like look.
Rear fascia lamps are key for road safety: they signal your vehicle’s width to other drivers at night or in low visibility, and work with the Model 3’s brake/turn signals to boost visibility. This CFN assembly mirrors the original’s light intensity and color temperature—no dim spots or mismatched glow with the right-side lamp. Its housing fits the 2023+ Model 3’s rear bumper cutout perfectly, sitting flush with the fascia to avoid gaps that trap dust or let water in (a common issue with generic lamps).
Built for durability, it uses a weather-sealed ABS housing (IP6K6 rating) that resists rain, car washes, and road salt—no internal water intrusion that damages bulbs or wiring. The LED bulbs (included in the assembly) are long-lasting too—up to 50,000 hours of use, so you won’t need frequent replacements. The lens is scratch-resistant and UV-protected, so it won’t fade or haze under sun exposure, keeping the light clear for years.
Installing it is straightforward for DIYers or pros. First, pop off the small access panel inside the left rear trunk (no need to remove the whole bumper). Disconnect the electrical connector from the old lamp, then unscrew the two mounting bolts holding the lamp to the fascia. Pull out the old assembly, slide this CFN lamp into place, reattach the bolts, and plug in the connector. Test the lights—brake, turn signal, and running light—to confirm they work, then replace the access panel.
Important: This is only for the left-hand side of 2023+ Tesla Model 3s. It won’t fit 2022 or older Model 3s (different rear fascia design) or right-hand side positions. It’s ideal for fixing faulty or damaged rear fascia lamps, keeping your Model 3 visible and safe on the road while maintaining its sleek rear-end look.
