Each fixture contains 12 high-visibility LEDs and is supplied as a hardwired three-wire assembly for easy installation. Note: the light functions as either a tail light (low brightness) or a stop\/turn light (high brightness) depending on the circuit; it cannot perform both modes at once.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these lights mount and what are the exact dimensions?\u003c\/h3\u003e\n\u003cp\u003eThe lights mount via a flange that matches a 105 mm inner diameter opening with a 105 mm hole spacing. The shallow 24 mm profile keeps the lamp close to the vehicle surface for a clean, low-profile installation. These physical specs make them suitable for many trailer and truck lamp cutouts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOuter diameter: 140 mm (5.5\")\u003c\/li\u003e\n  \u003cli\u003eInner diameter \/ hole spacing: 105 mm (4\")\u003c\/li\u003e\n  \u003cli\u003eHeight (depth): 24 mm (1\")\u003c\/li\u003e\n  \u003cli\u003eFlange mount compatible with standard 4\" round cutouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat wiring does the Partsam light use and how do I connect it?\u003c\/h3\u003e\n\u003cp\u003eEach lamp is hardwired with three color-coded conductors for simple connection to a vehicle harness. Ground the white wire, use the black wire for the low-brightness tail function, and the red wire for the high-brightness stop\/turn function. Always disconnect power before wiring and verify with a multimeter if unsure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite wire: ground (chassis)\u003c\/li\u003e\n  \u003cli\u003eBlack wire: low-brightness tail light\u003c\/li\u003e\n  \u003cli\u003eRed wire: high-brightness stop\/turn\u003c\/li\u003e\n  \u003cli\u003eDesigned for 12V vehicle electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these lights weatherproof and durable for marine or roadside use?\u003c\/h3\u003e\n\u003cp\u003eThe lens is sonic-welded to the housing so the lens and body form a single sealed unit, minimizing water intrusion and corrosion risk. Molded plastic housing and impact-resistant acrylic lens provide long-term outdoor resistance against road spray, salt, and UV exposure.

The dual-level wiring provides distinct low and high brightness modes to separate tail illumination from brake\/turn signaling.

They suit DIY installers and mechanics looking for straightforward three-wire hookups and durable, bright LED signaling without modifying existing cutouts.\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 these lights act as both tail and brake lights simultaneously?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The lamp can operate as either a low-brightness tail light or a high-brightness stop\/turn light, not both at the same time.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these fixtures waterproof for marine use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
