Red Oval LED Marker Light – 4" x 2" Sealed Trailer Clearance Lamp with Reflex Reflector, 12V DC, 2-Wire Hardwired, Screws Included for RV Camper Truck Boat
Meta Description:
Upgrade your trailer or RV with our Red Oval LED Marker Light. Measuring 4" x 2" x 1" with a 3" hole distance, it features a built-in reflex reflector, brighter and lower-draw LEDs than incandescents, and a hardwired 2-wire design (Red positive / Black ground). Universal 12V DC fitment for campers, trucks, trailers, boats, and SUVs. Includes mounting screws and a 12-month warranty.
"Are your trailer's old incandescent marker lights dim, drawing too much power, or constantly burning out? Tired of dealing with cracked lenses and water leaks that ruin the internal circuit?"
Standard incandescent bulbs are notoriously inefficient, generating excessive heat and draining your battery while providing weak, unreliable illumination. Worse, many aftermarket marker lights use cheap, brittle plastic that cracks when you tighten the screws, and poor sealing allows moisture to seep in, causing corrosion and short circuits.
Introducing the ultimate safety and style upgrade: the Red Oval LED Marker Light.
Engineered to be the exact same size as standard camper lights (4" x 2" x 1" with a 3" hole distance), this oval marker light is a direct, hassle-free replacement. It features high-intensity LEDs that are significantly brighter and draw far less current than old incandescent bulbs. The built-in reflex reflector eliminates the need for a separate reflector, saving you space and installation time. The circuit board is epoxy-sealed for maximum durability, and the unit is hardwired with just two wires (Red for positive, Black for ground) for a straightforward installation. Whether you're upgrading a trailer, RV, truck, or boat, this light delivers reliable, long-lasting visibility and safety.
Superior Brightness & Energy Efficiency
This Red Oval LED Marker Light is built with high-output LEDs that are dramatically brighter and draw significantly less current than traditional incandescent bulbs. This means your battery stays charged longer, your alternator works less, and you get a crisp, highly visible red light that ensures your vehicle's presence is unmistakable on the road, day or night.
Built-in Reflex Reflector – No Extra Parts Needed
Unlike standard marker lights that require a separate reflector to meet road safety standards, this unit features a built-in reflex reflector. This integrated design eliminates the need for additional reflectors, saving you money, simplifying your installation, and keeping your vehicle's exterior clean and streamlined.
Versatile Multi-Function Application
This oval light is incredibly versatile and can function as a Side Marker Light, Clearance Lamp, Identification Lamp, or Trailer Light. It is the ideal solution for the side at the rear corner (red) and the side at the front corner (amber) of your vehicle. You can also mount them along the top edge, sides, front, and back of campers for complete perimeter visibility.
Easy 2-Wire Hardwired Installation
Installation is simple and straightforward. The wires exit from the middle of the back of the light. It comes hardwired with 2 wires: Red is positive and Black is ground. Simply drill a hole in your trailer's frame to route the wires and install. Mounting screws are included for a secure fit.
Important Installation Notes for a Perfect Seal
Removable Lens: Please snap off the lens to install the light.
Avoid Over-Tightening: When you put the screws in, please do not tighten them too much, or the lens will crack.
Extra Sealing Recommended: After you snap the lens back on, please apply a little silicone or clear RTV all across the gap to help seal it. This prevents leaks into the light or where the wires enter. The circuit board itself is already epoxy-sealed for added protection.
Universal 12V DC Compatibility
These oval LED lights are universal for 12V DC vehicles. They are the perfect fit for RVs, campers, trailers, trucks, motorhomes, tractors, motorcycles, utility vehicles, fifth wheels, toy haulers, pickups, SUVs, vans, caravans, boats, lorries, and buses. If it runs on 12V and has a flat surface, this light will work.
