Each bulb combines 72 SMD 3014 chips and 4 SMD 3030 chips inside an aluminum housing with a projection lens and constant-current IC. Designed for 9–24V electrical systems, the pair offers long life, low power draw, and a crisp color change from white to amber for clear daytime running light and turn signal performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow bright are these bulbs compared with stock halogens?\u003c\/h3\u003e\n\u003cp\u003eThese LEDs are engineered to produce substantially more visible output than factory halogen bulbs while consuming far less wattage. The combination of numerous SMD chips, an aluminum body, and a projection lens concentrates light for stronger forward illumination and clearer signaling.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e72 SMD 3014 + 4 SMD 3030 chips per bulb for high lumen density\u003c\/li\u003e\n  \u003cli\u003eAluminum housing with projection lens for focused light\u003c\/li\u003e\n  \u003cli\u003eQuoted as over 300% brighter than typical halogen equivalents\u003c\/li\u003e\n  \u003cli\u003eLow power draw: ~3.5W (white) \/ ~4W (amber) per bulb\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my vehicle and how easy is installation?\u003c\/h3\u003e\n\u003cp\u003eThe bulbs are made to replace a wide range of 1157\/BAY15D family sockets and are plug-and-play in most applications.

These bulbs suit DIY installers and professional fitters upgrading older halogen systems or converting to efficient LED signaling on cars, trucks, trailers, and other 12V\/24V vehicles — provided socket fitment and measurements are checked beforehand. If your vehicle triggers hyper-flash or warnings, plan to add the recommended load resistors or an LED flasher relay.\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 bulbs plug-and-play?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — they fit most 1157\/BAY15D sockets, but confirm your socket type and measurements before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will these cause hyper-flashing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Some vehicles may hyper-flash; adding 50W 6-ohm load resistors or an LED flasher relay usually fixes it.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"iBrightstar","offers":[{"title":"Default Title","offer_id":48087029776542,"sku":"B07JC7233R","price":31.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/ibrightstar-front-package-view.jpg?v=1785914604","url":"https:\/\/northtrailauto.ca\/products\/ibrightstar-1157-bay15d-switchback-led-bulbs-white-amber-dual-function-drl-turn-signal-9-24v","provider":"North Trail Auto","version":"1.0","type":"link"}
