The package includes two 7 in sealed transit lights with 17 LEDs each and a 3-wire hardwire design, and the single biggest reason to buy is the watertight, sonically sealed construction that keeps the diodes and circuit board dry even if the light is submerged. For anyone restoring vintage campers or fitting a boat trailer, that durability is the main draw.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof sealed housing:\u003c\/strong\u003e The housing and lens are sonically sealed into a single unit so water cannot reach the LEDs or circuit board, making these ideal for boat and low-clearance trailers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple-function output:\u003c\/strong\u003e Each light operates as brake, tail and turn signal with 17 bright LEDs to improve visibility on roadways and in poor weather.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-wire hardwire hookup:\u003c\/strong\u003e The white wire is ground, red is stop\/brake and black is running\/tail, providing a conventional and reliable electrical connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface mount with gasket:\u003c\/strong\u003e The 4-hole surface mount and included mounting gasket make for straightforward installation on metal or composite trailer surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDOT compliant:\u003c\/strong\u003e Street-legal construction meets Department of Transportation lighting expectations for use on public roads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReflectorized inner lens:\u003c\/strong\u003e The inner reflectorized lens increases visibility when lights are not active and helps meet reflectivity requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese sealed 7 in LED lights are best for trailer owners, boat trailer users and owners of older campers or motorhomes who need a durable, weatherproof rear lamp that handles stop, tail and turn functions.
