DIY Fishing Headlamp Modification: Boost Brightness Easily

If you are interested in DIY fishing headlamps, you may want to take a look at this article.

If you have a small headlamp, but its illumination is very weak and not practical, and it still uses a straw-hat LED with only 50 mA.

Do not rush to throw it away, because you may suddenly discover that it actually comes with an infrared waving sensor, and it is quite sensitive.

You can refer to the image below.

You can see that this infrared sensing works very well.

So you can start modifying it yourself by first removing the screws on the back, and then opening the casing.

Then you can proceed to do some soldering.

You can directly change the current-limiting resistor, so the current becomes around 330–350 mA. (The original LED only has 50 mA.)

After you finish the modification, you will find that the practicality increases significantly, as it can illuminate a bright area within two meters, and you can also add a solid heat sink, which will make it more perfect.

You may suddenly notice that the internal pouch battery has already swollen, so you can replace it later when you have a Nokia battery available.

You can also add a small manual switch for convenient instant shutdown.

Completed.
