iBrightstar Super Bright 1157 BAY15D LED Bulbs White Amber Dual Function for DRL and Turn Signals

Overview

Meet the iBrightstar Super Bright 1157 LED bulbs, designed to replace standard BAY15D and 2057 style lamps with a versatile dual function. Use Xenon White for daytime running lights or parking light accents, and switch to Amber for turn signaling. The compact aluminum housing features a projection lens to help direct light where it matters, while a built in control circuit aims for consistent brightness and efficiency across voltage ranges.

What makes them stand out

Each bulb packs a robust LED array to deliver noticeable output without excessive power use. The 9 to 24 V operating range makes them suitable for a wide variety of 12 V and 24 V vehicles, offering flexibility for many setups.

• 72 SMD 3014 plus 4 SMD 3030 chips per bulb for bright, crisp illumination
• Full aluminum housing with a projection lens to maximize light output
• Built in constant current IC for steadier brightness and longer life

Dual function and practical use

Light up Xenon White for daytime driving and parking, or switch to Amber for turn signaling. The amber flash pattern is designed to enhance visibility on the road, and the white DRL option can provide daytime presence without overpowering other signals.

• Amber signaling offers clear, noticeable alerts
• White DRL mode increases daytime visibility while keeping a clean look
• Voltage range of 9 to 24 V supports many vehicle electrical systems

Notes and installation tips

LED bulbs often draw less power than stock lamps. Depending on the vehicle, you may need additional components to prevent hyper flashing or dashboard warnings.

• Consider a 50 W 6 Ohm load resistor or a dedicated flasher relay if advised by your vehicle manufacturer
• Always verify the item measurements and socket type before ordering to ensure a proper fit
