Buying Guide – How to Choose the Best LED Side Marker Lights for RV or Trailer
Selecting the right marker lights involves considering size compliance and durability. This section breaks down the key factors to help you decide.
Size and Shape
The physical dimensions of the light must match your vehicle's existing mounting holes. Most standard RVs use 4×2 inch rectangular or oval shapes. If you have custom fixtures you will need to measure the distance between screw holes carefully.
Measure your current holes to ensure a perfect fit.
DOT Approval
For legal compliance on public roads ensure the lights are DOT approved. This certification guarantees they meet safety standards for brightness and reflectivity.
Always verify DOT certification before purchasing.
LED Count and Brightness
Higher LED counts generally provide better visibility especially at night. Look for lights with at least 6 diodes for adequate output.
Check the LED count for best visibility.
Color Configuration
You typically need amber for front and red for rear markers. Buying sets that include both colors simplifies the setup process.
Ensure you get the right mix for front and rear.
Waterproof Rating
Since these lights are exposed to the elements choose options that are sonically sealed or waterproof. This prevents internal corrosion over time.
Look for sealed or waterproof housings.
Lens Type
Reflex lenses help reflect light when the vehicle is off increasing visibility. Snap-on lenses allow for easier replacement if damaged.
Choose reflex lenses for extra safety.
Installation Method
Most lights use surface mount designs with screws. Ensure the wires come out from a location that suits your routing needs.
Check wire exit points before installing.
Durability Features
Look for units with rugged ABS bases and acrylic lenses. These materials resist vibration and impact better than cheaper plastics.
Prioritize rugged materials for longevity.
How to Use and Care for Your LED Side Marker Lights for RV or Trailer
To install these lights correctly ensure the vehicle power is turned off before starting. Match the red positive wire to the positive side of your wiring harness and the black ground wire to a metal ground.
After mounting the lights securely check that all lenses are snapped in place tightly. This ensures the waterproof seal remains intact against rain and road spray during travel.
Periodically clean the lens surface with a soft cloth to remove dirt and road grime. Avoid harsh chemicals that could cloud the plastic and reduce light output over time.
