The bottom line: this kit is aimed at owners of trucks, trailers, RVs and vans who need a quick, low-cost way to add or replace multiple side marker lights without wrestling with complex wiring. The single biggest reason to consider it is the plug and play harness and connector system that reduces installation time to minutes and avoids individually splicing 20 separate lights.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug and Play Harness:\u003c\/strong\u003e The included 2-prong continuous wire harness and connector plug let installers avoid making 20 separate splices, saving time and reducing error points.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete 20-Light Package:\u003c\/strong\u003e The kit ships with 20 red side marker lamps and a roll of harness, providing a full set for trailers or fleets without sourcing parts separately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 3\/4 in LEDs:\u003c\/strong\u003e Each 3\/4 in marker houses three SMD LEDs to deliver about 60 lumen, providing visible side illumination for safety in traffic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong LED Life:\u003c\/strong\u003e The SMD LEDs are rated for long life, with an expected service life implied around 50,000 hours for reduced maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Wiring Polarity:\u003c\/strong\u003e The harness uses 12V DC with black as positive and white as negative, making human-error during hookup less likely when following color codes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis kit is well suited to DIYers, fleet maintenance shops, and owners of trailers, RVs, pickups and small commercial vehicles that need to replace or add multiple side markers quickly.
