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 3: Cleaning and Removing Unnecessary Parts

I removed unnecessary parts that I no longer need. Then I cleaned everything, especially the glass.

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.
