The pair is sonic-welded into a single waterproof unit so the lights withstand road spray and wet environments. Note: each lamp functions either as a tail light (low) or as a stop\/turn light (high), not both simultaneously; wiring determines the active mode.\u003c\/p\u003e\n\n\u003ch3\u003eHow rugged are these lights for outdoor and marine use?\u003c\/h3\u003e\n\u003cp\u003eThe Partsam housings and lenses are molded and sonic-welded into a single sealed unit to resist moisture and corrosion from exposure.

These Partsam 4\" red flange-mounted LED lamps are intended for vehicle owners, fleet managers, and DIY mechanics who need compact, weatherproof rear signaling lights for trucks, utility trailers, RVs, and boats. They suit anyone replacing worn incandescent fixtures with low-maintenance LEDs, or adding clear, sealed stop\/turn\/tail signals where space is limited. Confirm your mounting hole pattern and wiring plan before installation to ensure you achieve the desired tail or stop\/turn function.\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: Can one lamp act as both tail and brake light at the same time?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Each lamp functions either as a low-intensity tail light or a high-intensity stop\/turn light, not both simultaneously.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What are the wiring colors and functions?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: White is ground, black is low-brightness\/tail, and red is high-brightness\/stop-turn.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Partsam","offers":[{"title":"Default Title","offer_id":67591516127417,"sku":"B01E5AKKZK","price":62.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/partsam-front-view-flange-mounted-light.jpg?v=1790553989","url":"https:\/\/redleafauto.ca\/products\/partsam-4-red-led-stop-turn-tail-flange-mount-light-2pcs-12-diode-waterproof","provider":"Redleaf Auto","version":"1.0","type":"link"}
