LED Flashlight Repair

Being a flashlight lover, I have encountered different flashlight issues in the past that have forced me to know how to repair my flashlight. Normally, flashlight problems can be easily fixed by the user as long as he/she understands the different parts of the quality flashlights and how they function. So, when you realize that your flashlight is not working, you shouldn’t panic at all but take time and fix it well.

I have decided to share some information with you on how to fix your flashlight in case it encounters one of the most usual problems. But before you start, it is crucial that you comprehend how a flashlight works.

Flashlights are simple circuits. They are usually powered by batteries. The electrical current flows from the batteries, via the tail cap switch, via the outside of the flashlight body into the circuitry in the head of the light and then back into the batteries. If you are not conversant with how a flashlight works, you can always capture an image before disassembling it for repair. Some of the issues a flashlight faces are dim light, flickering, flashlight not turning on, leaked battery, and bad assembly. Let’s discuss them in detail as follows:

Light shinning dimly – This is a common problem with flashlights. The first thing you need to do if your flashlight is lighting dimly is the batteries. Check the batteries and get them replaced. It is possible that the batteries are weak and new batteries might make the flashlight shine bright again.

Flickering flashlight – when there is dirt or grime on the contacts of the flashlights, this causes the flashlight to flicker. Dirt or grime tends to accumulate on the internal contacts of the light. To get the flashlight functioning properly again, unscrew the head and tailcap off of the flashlight and clean the contacts where the body touches the head or tailcap. Utilize a damp paper towel. Get rid of dirt and grime and assemble the flashlight. In case this isn’t successful, then the issue might be with the circuitry which warranty covers.

Flashlight refuses to turn on – when your flashlight declines to turn on, there may be a number of issues causing it to-do-so. First of all, you should check the battery and see whether they are totally drained and replace them with new ones. Secondly, you can check the contacts and clean away the dirt and grime on the contacts. Also, you should check and see if there are loose parts such as the tailcap or switch.

Leaked battery – a leaked battery can cause your flashlight to refuse lighting on. This is very possible if you usually use alkaline batteries. To rectify this issue, you have o disassemble the flashlight and remove batteries.  If there is any sign of corrosion, dispose of the batteries. Search for white or rust-colored discoloration inside the body of the flashlight. If there is any, utilize a wire brush and a slightly acidic solvent to attempt and scrape away any corrosion. Alternatively, you can use a file to get rid of the rust inside the flashlight body.

Poor assembly of the flashlight – if you attempted to set apart the different parts of the flashlight, you should ensure that you reassemble them correctly. A slight mistake will make the flashlight to be loose and not function well. Ensure that every part is placed back in the right way including the O-rings and tailcap. A bad placement of just a single part will render the flashlight to be useless as it won’t light.

With this guideline, you can easily fix your flashlight. But if you try to fix the flashlight and it doesn’t work, it can be due to a bad circuit which needs to be replaced or repaired by the manufacturer. Check if you are still eligible for warranty before contacting the manufacturer for help.
