Introducing the JDM ASTAR Switchback Bulbs, designed to enhance your vehicle's lighting system. These versatile bulbs serve as both turn signals and daytime running lights, delivering improved visibility and style for your car. Crafted with high-quality aluminum and equipped with a constant-current driving IC, these bulbs ensure optimal performance and durability.

The unique switchback functionality allows for a seamless transition between amber and white light, making them a superior choice over traditional bulbs. Unlike most switchback bulbs, which flash amber-white-amber-white, the JDM ASTAR bulbs flash "amber-off-amber-off," providing a clearer indication to other drivers.

Measuring 0.85 inches in diameter and 2.51 inches in length, they fit a wide range of socket types including 3157, 3157A, 3057, and more. The advanced thermal management system guarantees fast heat dissipation, preventing overheating and ensuring longevity. To prevent hyper flash or non-blinking issues, a 50w 6ohm load resistor or flasher relay is recommended.

Key Features: Two bulbs per order for comprehensive coverage. Compatible with multiple socket types including 3157, 3157A, and 3457. Innovative flashing pattern: amber-off-amber-off for better visibility. Constructed from durable aluminum for enhanced heat resistance.
