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. Review: WOW!!! Auxbeam 3157 amber/white switch back👍🏾 - My 2013 Ford Taurus Auxbeam switchback turning signals are insane! I've been asked what I am running in my headlight housing because of how Bright the signals are by Taurus owners & other drivers who want them. Evening/Night video fully shows how great they are. People will know your intentions and that you are making a lane change & if your vehicle is disabled the hazard lights are equally insanely Bright! FANTASTIC PRODUCT! I finally have a legit daytime running light without having to use my headlight. I was running Lasfit but it was insufficient white light to use as a daytime running light because when the sun hit the front of the vehicle you couldn't tell if light was on. Finally, Auxbeam is the Brightest Amber & White switchback I've come across. Any questions feel free to Ask me. 2013 ford Taurus SEL 3157 bulb replacement absolutely no Hyperflash & no dashboard codes. They work perfectly & are a Superior Product. Well built and units look nice in headlight housing. 10 star 🌟 product. ## Features - CANBUS ERROR FREE: Super compatible for standard sockets rather than CK sockets. No hyper flash, no warning. With built-in CANBUS system, the 3157 dual color bulbs can alleviate decoding problems. Note: NOT fit TOYOTA TUNDRA and TOYOTA TACOMA. For super few sensitive models such as Silverado, RAM 1500/2500/3500 and Ford F150/F250/F350, extra resistors are needed or get from us. - 600% EXTREMELY BRIGHT: Sequencing 36Pcs Upgraded high brightness 3030SMD chips precisely around each 3157 led bulb, 28W per bulb, High Power and 600% brighter, providing 6500K Cool White light or 3500K Amber Yellow light. Instant-on response without warm-up time. More noticable when turning, guard your driving safety. - DUAL COLOR FUNCTION: This 3157 switchback led bulb with resistor lights up cool white for parking lights or daytime running lights (DRL) but amber yellow for turn signal lights. Unlike most turn signals flashing "amber-white-amber-white" on the market, the Auxbeam 3157 turn signals flash "amber-off-amber-off", making it easier to see from a distance. - 4-LAYER COOLING SYSTEM: IP68 waterproof and dustproof. The built-in stable current IC driver avoids digital or VHF radio signal interference. The latest cooling system - 12,000RPM silent fan + Copper cooling ring + 16Pcs heat sinks + 6063 aviation aluminum lamp body directly doubles heat dissipation, ensuring longer lifespan up to 60,000 hours. - NOT FIT CK SOCKETS: Only compatible with US standard sockets. Please refer to the CK sockets precautions on the pictures. Designed to be polarity sensitive, and if the bulbs don’t light up, please flip the plug and try again. Fit socket 3157, 3157A, 3157NA, 3057, 3057A, 3457, 3457A, 4057, 4157, 4157NA, T25, etc. No drilling, no wiring, no damage, just Plug and Play. - 360°FULL CLEAR BEAM: Each 3157 led bulb provides 360° full illumination without dark spot or shadow.
