Each bulb houses 11 amber and 11 white chips so the same lamp gives a crisp white output for parking or DRL duty and a clear golden amber for signaling. The design is intended for standard-base sockets (not CK type) and installs with a simple plug-and-play fit on compatible dual-function housings.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these bulbs switch between white and amber in everyday use?\u003c\/h3\u003e\n\u003cp\u003eThe Vouke 3157 switchbacks operate as dual-function lamps: white LEDs illuminate for parking lights or daytime running lights, and the amber LEDs flash when you activate the turn signal. The switching is instant and uses the existing socket functions, so no wiring change is required on compatible vehicles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite mode: 11 x 5730 SMD chips per bulb for crisp parking\/DRL light.\u003c\/li\u003e\n  \u003cli\u003eAmber mode: 11 x 5730 SMD chips per bulb for bright golden turn signals.\u003c\/li\u003e\n  \u003cli\u003eFlashing pattern: clear yellow-off-yellow-off sequence for visibility.\u003c\/li\u003e\n  \u003cli\u003eStandard-base fit: designed for 3157-style sockets, not CK type.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these LEDs fit my car and are they easy to install?\u003c\/h3\u003e\n\u003cp\u003eThey are designed as direct replacements for dual-function 3157-style bulbs that combine parking\/DRL and turn-signal roles in one lamp. Installation is straightforward—remove the old bulb and insert the Vouke 3157 pair into the same socket—but confirm your socket is standard (not CK) and that your original bulb handled both functions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFitment: standard 3157 base, cross-references listed in product specs.\u003c\/li\u003e\n  \u003cli\u003eCompatibility check: only replace bulbs that had two functions originally.\u003c\/li\u003e\n  \u003cli\u003ePlug-and-play: no special tools or rewiring for compatible housings.\u003c\/li\u003e\n  \u003cli\u003ePackage includes two bulbs—one pair for both sides.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDo I need resistors or will the car flash correctly after installation?\u003c\/h3\u003e\n\u003cp\u003eBecause LEDs draw far less current than incandescent bulbs, some vehicles may show hyper-flash or a fast flashing rate after replacing turn-signal bulbs.

Choose Vouke 3157 switchbacks if you want plug-and-play installation, improved visual presence, and dual-color functionality in one bulb pair. Do confirm your socket type (standard 3157, not CK) and be prepared to add load resistors or a compatible relay if your vehicle exhibits hyper-flashing after installation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these Vouke bulbs compatible with CK-type sockets?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These bulbs use a standard 3157 base and are not compatible with CK-type sockets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will I need extra parts to stop hyper-flashing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Some cars require 50W 6Ω load resistors or an LED-compatible flasher relay to correct hyper-flash.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Vouke","offers":[{"title":"Default Title","offer_id":67592785461433,"sku":"B01M9CXY2U","price":60.78,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/vouke-3157-front-view-packaging.jpg?v=1790568111","url":"https:\/\/redleafauto.ca\/products\/vouke-3157-switchback-led-bulbs-pair-dual-color-white-amber-22-smd-5730-chips-standard-3157-socket","provider":"Redleaf Auto","version":"1.0","type":"link"}
