iBrightstar Switchback LED Bulbs 3157/3457 — White DRL and Amber Turn Signals

Dual-Function Switchback LED Bulbs for DRL and Turn Signals

Upgrade your vehicle with the iBrightstar Switchback LEDs. These bulbs illuminate Xenon White for parking lights or daytime running light (DRL) and seamlessly switch to Amber for turn signaling. The result is a crisp, high-contrast look that helps improve daytime visibility and signaling clarity without requiring a separate component for each function.

Key Features and How They Help

• 72SMD 3014 and 4SMD 3030 chips per bulb deliver bright, even light for both DRL and amber signaling.
• Working voltage from 9 to 24V makes them compatible with many 12V and 24V vehicles.
• Output of 3.5W (white) and 4W (amber) provides energy-efficient operation with strong light output.
• Color options include White for DRL and Amber for turn signals, enabling clear, distinct signaling.
• Full aluminum housing with a projection lens optimizes light output and helps with heat distribution for longer life.
• Built-in constant current IC supports stable performance and lower power consumption over time.
• Service life is rated up to 30,000 hours, reducing the need for frequent replacement.

Compatibility, Installation, and Practical Use

Designed for a wide range of sockets, including common 3157 families (3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157, and more). The bulbs are easy to install with a plug-and-play approach for quick upgrades.

In use, the white mode provides bright daytime visibility as you drive, while the amber mode offers clear, attention-grabbing signaling on the road. The dual-function design can simplify your lighting setup and reduce the number of separate bulbs you need to stock.

Important Reminders and Tips

• Set of 2 bulbs included; verify measurements and socket type before placing an order.
• Some vehicles may require a 50W 6-Ohm load resistor or an appropriate flasher relay to prevent hyper flashing or dashboard warnings.
• Brightness can vary with vehicle electrical systems and wiring; results are described as possibilities rather than guarantees.

With iBrightstar, you get a reliable, dual-function LED upgrade that emphasizes visibility and signaling clarity. Consider this upgrade if you want a streamlined, high-contrast look for DRL and a distinct amber signal for turns, all powered by an efficient, long-lasting design.
