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.
