Built with 34 high-power 3030 LED chips per bulb, an HD glass lens, and an intelligent constant-current driver, they offer efficient light output and temperature regulation across a 9–18V range. The package includes two bulbs and install resistors to help prevent hyper-flash on vehicles that require additional load.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these bulbs improve visibility during daytime driving?\u003c\/h3\u003e\n\n\u003cp\u003eThe white DRL\/parking mode enhances vehicle presence without overwhelming other drivers, while the amber turn signal provides a clear, familiar color for signaling.

SEALIGHT provides two 50W 6Ω resistors in the kit and the bulbs are designed with a built-in constant intelligent IC driver to minimize radio interference and stabilize current across 9–18V. Some cars may still require installing the resistors or an alternate flasher relay to eliminate hyper-flash.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncluded 50W 6Ω resistors help mimic filament bulb load\u003c\/li\u003e\n  \u003cli\u003eBuilt-in IC driver reduces interference and stabilizes output\u003c\/li\u003e\n  \u003cli\u003eCompatible with a wide voltage range (9–18V)\u003c\/li\u003e\n  \u003cli\u003eMay still need resistors or relay for specific vehicle systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and what sockets are supported?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is designed to be plug-and-play for US-standard sockets; these are non-polarity bulbs so there’s no need to test orientation.

They suit owners replacing fractured or dim factory bulbs, enthusiasts upgrading to LED lighting, and anyone whose vehicle wiring expects a dual-function bulb. If your car signals hyper-flash after installation, use the included resistors or consult a mechanic or electrician for a compatible flasher relay to achieve correct blink rate.\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 my 3157 socket?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — they are compatible with 3157\/3057\/3457\/4157-style sockets and other listed variants, designed for dual-function parking and turn signal lamps.\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-flash?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Possibly — resistors are included; install them if your vehicle hyper-flashes or consult a flasher relay option for permanent resolution.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"SEALIGHT","offers":[{"title":"Default Title","offer_id":67588764958905,"sku":"B0FHPRM44C","price":83.81,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/sealight-3157-front-view.jpg?v=1790524447","url":"https:\/\/redleafauto.ca\/products\/sealight-3157-switchback-led-bulbs-dual-color-amber-white-2-pack-anti-hyper-flash-resistors-included","provider":"Redleaf Auto","version":"1.0","type":"link"}
