At just 3/4 of an inch, they pack a punch with 60 lumens of brightness from three internal SMD LEDs, making them ideal for marking the sides or undercarriages of trailers, boats, or trucks.

It is a smart, cost-effective way to add visibility and a polished look to your semi-truck without a full headlight overhaul. Just ensure you have your H4651 or H4666 style assemblies ready for the installation.

Visibility issues during night hauling or low-light maneuvering often lead to dangerous situations on the road. This 30-piece Partsam kit solves that by providing a massive variety of amber, red, and white marker lights to clearly define your vehicle's footprint. Each slim 3.8-inch unit draws less than one watt, making them incredibly efficient for long-term use on trailers, RVs, or even boats.
