DIY vintage LED lamp from old bike lights
Some time ago I found an old bicycle light in my garage. It is the original lamp
of the well-known BOSCH brand. This lamp has many scratches and a few dents, but it
only gives it an original style. I do not know exactly where to mount it, maybe
it will light up my desk, or maybe do some lighting in the workshop or gazebo.
In this projection, I used the LM2596 the same one I used when building
other LED lamp Diy LED lights panel for 5$ - Cheap and Easy 6 x 10W

Step 4: Drilling holes

Because I have 3 mm screws and in LEDs are 2.5 mm holes, so I need to drill to 3mm.

I drilled 3 holes, two 3mm on LED and one 4mm on cord.

Because the edges are not nice, I smooth them with a much larger drill bit.

Step 5: Voltage setting

Before soldering LM2596 to LED I check the voltage and set them to about 9.5V.
Then hook LM2596 to the LED and set the voltage again. My LED diodes
have not been set to full power, so I have no problem with overheating.
