Each bulb uses 16 high-power 3030 LED chips and an HD glass lens to concentrate light while keeping power draw low. Built-in constant-current electronics and an aluminum circuit board manage heat and electrical stability across a wide 9–18V input range, making them suitable for most cars, trucks, and SUVs that accept 3157-style sockets.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these AUXITO bulbs switch between white and amber?\u003c\/h3\u003e\n\n\u003cp\u003eThe bulbs are designed for dual-function housings that use one filament for parking\/DRL and the other for turn signals. When the parking light circuit is powered, the LEDs emit bright white; when the turn signal circuit activates, they switch to amber and flash. AUXITO’s switchback pattern intentionally flashes amber-off-amber to maximize visibility and avoid the confusing amber-white alternating flash some other products produce.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDual-color operation: white for DRL\/parking, amber for turn signal\u003c\/li\u003e\n  \u003cli\u003eDistinct amber-off-amber flash pattern for clearer signaling\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 3157-family sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill installation require extra parts or technical changes?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is plug-and-play for most vehicles thanks to a non-polarity design and standard 3157-fitment. However, because many modern cars monitor bulb load, you may encounter hyper-flash or a no-blink condition. AUXITO includes 50W 6-ohm load resistors in the package to correct hyper-flash, and in some cases an upgraded flasher relay may be recommended.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNon-polarity plug-and-play for 3157, 3057, 3457, 4157 sockets\u003c\/li\u003e\n  \u003cli\u003eIncluded load resistors to prevent hyper-flash where needed\u003c\/li\u003e\n  \u003cli\u003eMay require relay upgrade for certain vehicle monitors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow bright and reliable are the 3030 LED chipsets used by AUXITO?\u003c\/h3\u003e\n\n\u003cp\u003eEach bulb contains sixteen 3030 high-power LEDs that provide a balance of brightness and energy efficiency. The HD glass lens focuses output for improved penetration and a cleaner light pattern, while the aluminum circuit board and intelligent constant-current IC help control heat and keep the LEDs operating stably across voltage variations. These design choices improve longevity and reduce the chance of interference with radios or vehicle electronics.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e16 high-power 3030 LED chips per bulb for robust light output\u003c\/li\u003e\n  \u003cli\u003eHD glass lens for focused beam and improved visibility\u003c\/li\u003e\n  \u003cli\u003eAluminum circuit board + IC driver for heat dissipation and electrical stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles and sockets are these AUXITO switchback LEDs compatible with?\u003c\/h3\u003e\n\n\u003cp\u003eThe bulbs are made to fit a broad range of 3157-style sockets, covering many passenger cars and light trucks that use a single bulb for parking and turn functions. Check your vehicle’s owner manual or existing bulb code to confirm fitment; the package lists common compatible socket numbers. Because the bulbs perform two functions from the same unit, they’re intended only for housings wired for dual-function bulbs.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFits: 3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157\u003c\/li\u003e\n  \u003cli\u003eBest for dual-function parking + turn signal housings\u003c\/li\u003e\n  \u003cli\u003eVerify bulb code before purchase to ensure compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Drivers who want a clean, modern look and clearer signaling from their parking lights and turn signals without complex wiring. These AUXITO 3157 switchback LEDs suit DIY installers who need plug-and-play replacement with included resistors, fleet owners seeking durable, low-power lighting, and owners of vehicles that use the 3157 family of sockets who want dependable white DRL\/parking light performance and attention-grabbing amber turn signals.\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: Do these bulbs fit in any 3157 socket?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—these bulbs are compatible with most 3157-family sockets, but verify your vehicle’s bulb code to confirm fitment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will I need resistors to stop hyper-flashing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: AUXITO includes 50W 6-ohm resistors; install them if your vehicle shows hyper-flash or a no-blink condition.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"AUXITO","offers":[{"title":"Default Title","offer_id":48086274244766,"sku":"B0756B3T1D","price":45.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/auxito-3157-front-packaging_36b4ed31-1b74-4698-ac7a-cf33b97fccb9.jpg?v=1785893103","url":"https:\/\/northtrailauto.ca\/products\/auxito-3157-switchback-led-turn-signal-bulbs-dual-color-white-amber-16-3030-chips-pack-of-2","provider":"North Trail Auto","version":"1.0","type":"link"}
