When it comes to sealing RV marker lights, you have several options.

  • Silicone is the most popular sealant used on RV lights because it is a superior waterproofing material. It not only forms a strong bond but also offers resistance against UV light and moisture, making it an excellent choice for protecting against water infiltration and deterioration from environmental conditions.
  • Polyurethane foam sealant has superior adhesion and provides superior weather resistance as well as excellent painting ability.
  • If you are looking for something more flexible, you can use butyl or rubber sealers which are easily applied with a brush or an adhesive gun, both of which allow for easy adhesion to hard-to-reach surfaces.
  • Finally, RV owners can also choose natural rubber sealants such as neoprene or EPDM (ethylene propylene diene monomer) that offer superior weather protection while allowing some flexibility so they don’t crack under pressure or strain on the connections between parts. That said, these types of materials are not as effective in dampness and may not provide tight seals around certain edges with large gaps.

Whatever kind of seals you choose for your lights, make sure to read all instructions thoroughly before applying the solution and follow the given directions for best results!

How do you seal RV clearance lights?


Sealing a recreational vehicle (RV) clearance light is an important step for selecting the right sealant to ensure the light operates correctly and the RV remains water-tight.

When selecting the sealant, you’ll need to consider several factors, including the age of your RV, the type of bulb used in the clearance lights, and what type of sealing materials is best for your particular application.

The basic technique involves ensuring proper surface preparation and then applying a sealant that will stretch or contract with normal temperature ranges while also repeating a finishing coating like paint or vinyl. Here are some tips to help you get it right:

  1. Clean off any dirt or grime from the RV light by using soap, water, and stiff brushes. Take care not to scratch or otherwise damage the surface while cleaning it.
  2. Inspect all wiring around the area of installation and repair any broken insulation as necessary. Make sure that all electrical connections are secure before continuing with sealing process.
  3. Examine substrate for brittle metal surfaces, rust spots, holes or gaps that require repair before winterizing your RV clearance light using this guide’s steps for installation purposes.

What is the black sealant used on RVS?

When shopping around for the right sealant for re-sealing RV marker lights, it is important to understand what benefits you’re looking for.

The most popular sealant used on RVs is a black butyl rubber sealant. It is a specially formulated rubber compound that has low viscosity, and adheres to most surfaces including metal, wood, plastic, and other materials.

It offers superior resistance to extreme temperature swings and resistant to UV radiation without breaking down. It provides superior protection against moisture, dust and dirt when applied around the lights on your RV.

A good quality butyl rubber sealant will also have excellent anti-corrosive properties, making it ideal for use outdoors in harsh weather conditions.

What color should RV marker lights be?

When installing or repairing RV marker lights, it is important to choose the appropriate color for the lights. These are typically categorized as either side marker lights (red and amber) or identification lights (white), and must comply with applicable laws in your state.

Side marker lights indicate the dimensions of an RV and tend to be mounted on the corner areas. They can also be placed on top surfaces, along the roof line, or used as backup lighting. Side marker lights must be red on the right side of RVs over 8 feet wide, and amber on the left side of RVs over 8 feet wide. If a trailer is less than 8 feet wide, both sides should have amber lighting.

Identification lights are typically required to operate while driving and parked, with white being the standard color for both sides of an RV over 8 feet wide. RVs under 8 feet wide only need one light each in front and back that is white in color. Be sure to check local regulations for any specific requirements in your area before installing these RV marker lights; failure to adhere to applicable laws could result in hefty fines or other penalties.

You’ll also want to make sure you choose a reliable sealant that can withstand exposure to outdoor elements when it comes time to install your markers–properly sealed markers prevent water damage from ruining your lights!
