iFunyLED 3157 Switchback LED Turn Signal Bulbs — 4 Pack Xenon White/Amber

Overview

Upgrade your vehicle’s front lighting with the iFunyLED 3157 Switchback LED bulbs. This four‑pack delivers dual-function illumination in one compact bulb, combining bright Xenon White parking/DRL lights with crisp Amber turn signals. The result is a cohesive, two-tone look that enhances daytime visibility and signaling clarity on the road.

Key benefits at a glance

• Dual-color performance: Xenon White DRL/parking light paired with Amber turn signal for clear signaling
• Bright, wide coverage: 360-degree illumination minimizes shadows and dead angles
• Efficient operation: 3.8W per bulb with low heat generation for longer life
• Broad compatibility: 12V–24V range suits a wide range of vehicles
• Common-bulb compatibility: Works with multiple 3157 family models (3047, 3057, 3357, 3457, 4057, 4114, 4157, 3057A, 3157A, etc.)

How it works in practice

In practical use, the white Xenon glow serves as daytime visibility and parking light, while the amber signal flashes clearly when you indicate a turn. The amber pattern is designed for high visibility with an amber-off-amber-off rhythm, which some drivers find easier to notice in busy traffic. This setup is ideal for drivers seeking a unified front-light upgrade without juggling separate bulbs.

• Application: Light up Xenon White for parking/DRL and Amber for turn signaling
• Pattern: Amber signaling is designed for clear recognition among surrounding traffic

Performance and reliability

Each bulb packs 22 pieces of high-brightness 5730 LEDs, delivering robust illumination across a full 360-degree field. With low power draw and efficient heat dissipation, the bulbs are designed for extended life under typical driving conditions. This set includes four bulbs, providing a complete front-end upgrade for many vehicles.

• High brightness: 22 LED chips per bulb yield strong, even output
• Long life potential: efficient heat management supports durability
• Pack contents: four bulbs for a full front-lighting upgrade

Important notes and setup tips

Before purchasing, confirm your bulbs are designed to combine both parking/DRL and front turn signal functions in one unit; otherwise, you may not achieve the expected two-tone lighting. If you encounter hyper-flash or warning messages on the dashboard, a 50W 6Ω resistor or an appropriate flasher relay can help. If you need guidance, our support team is ready to assist.

Real-world use cases

For daily commutes and urban driving, the Xenon White DRL boosts daytime presence, while the Amber turn signals provide clear, immediate signaling to other drivers. The four-bulb kit enables a uniform upgrade across the front to improve both look and signaling performance.
