Securing your LED light bar is a multi-step process that involves several tools and materials. Before getting started, make sure you have the following on hand:

  1. Rubber sealant or silicone
  2. Masking tape
  3. Foam weather stripping
  4. Scissors or utility knife
  5. Clean cloths or paper towels
  6. Water-based degreaser or rubbing alcohol
  7. Drill and drill bits
  8. Wire cutters or scissors
  9. Small screwdriver
  10. Clean, dry workspace

With your supplies in hand, you’re ready to get started.

10 Easy Steps on How to Seal Led Light Bar

Step 1. Clean the Surface:

Before applying any sealant to your LED light bar, ensure it is clean and free of dust or dirt. Use a water-based degreaser or rubbing alcohol to clean any residue off of the light’s surface, and dry it thoroughly with a clean cloth or paper towel. This will help ensure that your sealant adheres to the surface properly.

to Your Led Light Bar

Step 2. Apply Your Sealant:

Once your LED light bar is clean and dry, you can apply your sealant. Begin by carefully applying a layer of sealant across the surface of your light bar, ensuring that it is evenly applied and reaches all edges. If you are using a silicone-based sealant, make sure to let it dry according to the instructions on the packaging before moving on to the next step.

Step 3. Let the Sealant Dry:

In most cases, you will need to let the sealant dry for at least 24 hours before moving on to the next step. While some sealants may require more or less time to set, we recommend following the manufacturer’s suggested timeframe for best results. Be careful not to disturb or touch the sealant too much during this process, as it can weaken its adhesion and compromise how well your light bar is sealed.

Step 4. Cut Your Weather Stripping:

Once your sealant has fully set, you can begin cutting and applying your weather stripping around the edges of your LED light bar. This will help create a tight seal between the light and any other surfaces in your vehicle, further protecting against moisture, dust, and dirt getting inside. Before cutting the strips, lay them down on a flat surface so they fit smoothly against each edge. It’s usually easiest to apply these strips by hand, but you may also be able to use a small screwdriver if needed.

Applying Your Weather Stripping

Step 5. Test Your Seal:

Once your weather stripping is in place, you can test how well your seal is holding up by running a damp cloth along the surface of your LED light bar. If any water or liquid makes its way through, you may need to apply more sealant and repeat the process until there are no openings or gaps in the seal. Otherwise, you’re ready to move on to the next step.

Step 6. Attach Your Light Bar:

Once your seal is fully set, you can begin attaching your light bar to its intended mounting location in your vehicle. Depending on how it was installed, this may require the use of a drill with various bits or other tools depending on how it was secured. Before any drilling or bolting takes place, consult the manufacturer’s instructions and ensure that all electrical wires are properly disconnected from the light bar as needed.

Step 7. Get in the Garage!

Once your LED light bar is securely attached and sealed, it’s time to put it into your vehicle and head to the garage for peace of mind. It’s important to keep an eye on how well your seal holds up over time. So if you notice any cracks or gaps starting to form, take some time to address the issue immediately. This can help prevent any moisture, dust, or dirt from getting inside and damaging your light bar.

Step 8. Maintain Your Seal:

To keep your LED light bar sealed properly over the long term, you must continue to maintain and monitor the sealant as needed. This may include cleaning and reapplying sealant periodically or replacing weather stripping as needed. You can also use this opportunity to inspect how well your light bar is working and how much wear it has sustained from regular use in your vehicle. If you notice any issues with durability or performance, it may be time for a replacement.

Step 9. Stay Safe on the Road:

Finally, no matter how well you seal and maintain your LED light bar, it’s important to always drive safely on the road. This means taking any necessary precautions to avoid getting in an accident or putting yourself or others at risk. Whether this involves keeping your hands on the wheel at all times or simply driving with caution, staying safe is key to making the most out of your LED light bar and enjoying it for years to come.
