My car is taurus, I have installed to my car, it is working fine dual function are working, it is really very nice, and recomended, I will observe until 2 week for the last review

Looks great

So far working without issue on the front of my 2005 Cadillac CTS-V. When in daytime running mode they switch to low brightness and when on blinker at full brightness then back to daytime mode. Very bright. I have regular bulbs in back so not sure if using rear led bulbs would cause these to hyperflash. Install was fast and easy on my car others may differ.

Strongly recommend they are super bright and the switchbacks look much better than the original lights

I recently purchased the running light and turn signal light combo for my vehicle, and I must say, I am thoroughly impressed with its performance and functionality. This product truly offers the best of both worlds, providing a bright white running light for enhanced visibility during normal driving conditions, as well as an attention-grabbing amber turn signal light for when I need to indicate a lane change or a turn. One of the standout features of this product is its seamless transition between the white running light and the amber turn signal light. The transition is smooth and instantaneous, ensuring that other drivers on the road can easily recognize my intentions. This has significantly improved the safety aspect of my driving experience, as I feel more confident that my signals are clearly communicated to those around me. In terms of brightness, both the running light and turn signal light are exceptionally bright, making them highly visible during day and night. The white running light provides excellent illumination, enhancing my visibility to oncoming traffic and pedestrians. Meanwhile, the amber turn signal light grabs attention with its vibrant color, ensuring that my intentions are noticed even in busy traffic situations. The build quality of this product is also top-notch. It feels sturdy and durable, capable of withstanding various weather conditions and vibrations on the road. I appreciate the attention to detail in the design, as it seamlessly integrates into my vehicle's aesthetics without looking out of place. Overall, I am extremely satisfied with this running light and turn signal light combo. Its ability to switch between the white running light and the amber turn signal light is a game-changer for me. The brightness, durability, and ease of installation make it a fantastic choice for anyone looking to enhance their vehicle's lighting system. I highly recommend this product to fellow drivers who value safety and versatility on the road.
