The UBL 3.8 Inch Side Marker Lights are designed to deliver dependable visibility and long-lasting performance for a wide range of vehicle and marine applications. Each light features six high-intensity 2835 SMD LEDs, producing a stable, bright output that enhances safety and ensures your vehicle or equipment remains clearly visible in low-light conditions.

Built with durability in mind, these side marker lights feature a fully sealed construction with secure closures at both the front lens and rear wire lead. Additional sealing at the wire entry point helps protect against moisture, dirt, and vibration, making these lights well-suited for demanding environments while maintaining an easy surface-mount installation.

Installation is simple and efficient thanks to a two-wire setup—white for positive and black for negative—allowing for quick integration into most 12V systems. The included foam tape base assists with positioning and mounting, while bolts and nuts provide a secure fit. For added installation flexibility, washers may be used beneath the foam tape base to avoid drilling a center wire hole when needed.

Compatible with most 12V electrical systems, the UBL 3.8 Inch Side Marker Lights are highly versatile and can be used on trucks, trailers, buses, RVs, and various marine applications. Whether used as side marker lights, indicator lights, accent lighting, or supplemental visibility lighting, these amber LEDs offer reliable performance and a clean, professional appearance.
