Diode Dynamics Switchback Turn Signal LEDs for 4Runner (pair) (2026+)

Upgrade the front turn signals on your Toyota 4Runner with modern LED indicators that deliver crisp, instant on-off performance. Designed as a direct 7443 replacement, these plug-and-play bulbs provide greater output than factory incandescent bulbs while maintaining proper dual-brightness operation for a clean, OEM-style upgrade.

Important note

• Halogen only: These bulbs are a direct replacement for factory halogen bulbs and will not replace OEM LED bulbs.
• Resistors required: Due to lower power draw, LED resistors are required to prevent hyperblinking on PWM/CANBUS systems.
• Switchback visibility: Clear reflectors or lenses are required to properly see the white running light output on switchback models.

Features

• Modern LED appearance: Instant on and off response for a clean, updated look.
• Direct replacement: Designed specifically for Toyota 4Runner front turn signal bulbs.
• Plug-and-play design: Installs using factory 7443 bulb size with no modification required.
• Increased output: Provides greater light output than factory incandescent bulbs.
• Dual-brightness operation: Maintains proper low and high brightness levels for parking and turn signal functions.
• Switchback functionality: White running light switches to amber when turn signal or hazards are activated.
• Accurate lumen ratings: Measured output values, not calculated estimates.
• Protected circuitry: Constant-current inductive design with transient suppression for long-term reliability.
