How to Stop Solar Lights from Flashing

Solar lights are an eco-friendly and cost-effective way to illuminate your outdoor space. However, one common issue that can be frustrating for solar light owners is when their lights start flashing or flickering unexpectedly. This can not only diminish the aesthetic appeal of your outdoor area, but it can also impact the functionality and performance of the solar lights.

How to Stop Solar Lights from Flashing

Fortunately, there are several simple steps you can take to stop solar lights from flashing and ensure they operate smoothly. From checking the battery connections and cleaning the solar panels to adjusting the settings and troubleshooting the circuit, this guide will provide you with how to stop solar lights from flashing and practical tips and techniques to resolve the flashing issue and keep your solar lights shining bright. 

With the right approach, you can enjoy consistent and reliable illumination from your solar lights and enhance the ambiance of your outdoor space.

Why Is Solar Street Light Blinking?

Solar streetlights are designed to switch off and on automatically when it senses a lack of sunlight. When the solar panel is not receiving sufficient energy from the sun, the battery will start to discharge, resulting in short cycles of light turning off and on. This process is called “flashing,” and it can be quite annoying if you live near a solar street light.

In most cases, flashing is caused by either a weak battery or an insufficient amount of sunlight hitting the solar panel. If your solar street light flashes frequently, it’s likely that its battery needs to be replaced or its solar panel must receive more direct sunlight for charging. Let’s take a look at some of the main causes of a flashing solar street light and what you can do to stop it.

One of the most common reasons for your solar street light to flash is a weak or dead battery. If your solar street light has been installed for a while, its battery may have depleted beyond repair and needs to be replaced in order for your light to work properly. You should check the manufacturer’s instructions for how to replace the battery correctly.

Another possible cause of a flashing solar street light is insufficient sunlight exposure. Solar panels must receive direct sunlight in order to generate enough energy to power your solar street lights throughout the night. If there are any obstructions, such as trees or buildings blocking the sun from reaching your panel during daylight hours, then this could be the reason why your solar street light is flashing.

8 Methods How to Stop Solar Lights from Flashing

Use a Higher Quality Light

1. Use a Higher Quality Solar Light 

One of the best ways to prevent your solar lights from flashing is to use a higher-quality light. There are a lot of solar lights on the market that are very cheaply made, and these are more likely to have issues with flashing. If you spend a bit more money on a higher-quality light, you will be less likely to have problems.

To find a good quality light, look for lights with larger solar panels and brighter LED bulbs. These will be more reliable in the long run. If you purchase a solar light that is made from durable materials, it will also last much longer. However, it is important to keep in mind that even the best-made solar lights may still flash occasionally.

2. Keep the Solar Panel Clean 

If the solar panel on your light is dirty, it can prevent the light from charging properly. This can cause the light to flash or flicker. Be sure to keep the solar panel clean so that it can charge properly. You can clean the solar panel with a damp cloth or brush.

Avoid abrasive cleaners and scrubbing too hard as this could damage the panel. Also, be sure to avoid exposing the panel to water or moisture. However, if the panel does get wet, use a dry cloth to remove any water or moisture from the panel.

3. Replace the Batteries 

If your solar lights are flashing, one of the first things you should check is the batteries. Over time, batteries can lose their ability to hold a charge, and this can cause the light to flash. If your batteries are more than a year old, you should replace them. Make sure to use the correct type and size of battery for your solar lights.

Check the manufacturer’s instructions before buying new batteries. While you’re at it, check the wiring in the solar lights to make sure it is not damaged or loose. If so, this could also be causing the lights to flash. To access the wiring, you will need to open the lights up. Refer to the manufacturer’s instructions on how to do this safely.

4. Check the Wiring

Be Sure to Keep the Solar Panel Clean

If your solar lights are flashing, it could be due to a problem with the wiring. Sometimes, the wires can become loose or damaged, and this can cause the light to flash. Be sure to check all of the wirings and make sure that everything is secure and in good condition.

If the wiring is damaged, it should be replaced. You may need to contact a professional electrician to do this job properly. If the wiring is in good condition, then it is likely something else is causing the flashing. While it is possible for the wiring to be damaged, this issue is typically not the cause of flashing.

5. Use LED Bulbs

If your solar lights are equipped with LED bulbs, they will be less likely to flash than if they have traditional incandescent bulbs. This is because LED bulbs use less power and generate less heat, which can cause flickering or flashing. If you need to replace bulbs in your solar lights, consider switching to LED bulbs for increased reliability.

If your solar lights are not equipped with LED bulbs, you may need to upgrade the unit to one that is. To do this, you’ll need to consult your manufacturer’s instructions. However, LED bulbs can be more expensive than traditional bulbs, so you’ll need to weigh the cost of replacement against that of a new unit.

6. Move the Solar Panel to a Sunny Location 

If your solar panel is not in a sunny location, it will not be able to charge properly, leading to flashing lights. Make sure that the panel is in a spot where it will be receiving direct as this can cause your light to flash.

Be sure to place the solar panel in an area where it will get direct sunlight for at least six hours each day. You can also try angling the panel towards the sun if it is not in a location that receives direct sunlight. However, if the area does not get enough sunlight to charge the panel, you will need to find a better location for it. While it may be difficult to move the panel, it is essential in order to stop the flashing.

7. Cover the Solar Panel when Not in Use 

Replace the Solar Light Batteries 

If you are not using your solar lights, be sure to cover the solar panel so that it does not become dirty or damaged. This will help to keep it in good condition and prevent any problems with flashing or flickering. If you live in an area with a lot of snow or rain, it is especially important to cover the solar panel so that it can stay dry and clean.

This will also help to keep the solar lights from overheating, which can lead to flickering or flashing. While it is not necessary to cover the solar panel every single time you turn off your lights, it can be a good idea to do so on days when the weather is bad or if you know that your lights will not be in use for a while.

8. Turn off Other Electronic Devices 

If you have other electronic devices near your solar lights, they can interfere with the charging process and cause the light to flash. Be sure to turn off any other electronic devices that are within range of your solar lights so that they do not interfere with charging.

Additionally, make sure that your solar lights are far away from any other electronic devices to minimize the risk of interference. If you still have problems, try moving your solar lights further away from any electronic devices. It is also important to ensure that there are no other light sources in the vicinity of your solar lights, as this can interfere with their charging process.

Solar Lights Are Equipped With Led Bulbs


In the end, troubleshooting and maintaining your solar lights does not have to be a daunting task. It requires time, patience, and some light understanding of electrical systems. With the right knowledge and guidance, you can identify the issue with your solar-powered outdoor lights with relative ease.

Now that you know how to stop solar lights from flashing, you are better able to maintain them year-round! Your outdoor space will benefit tremendously from having well-working or fully functional solar lighting products that give it the style it deserves.
