Neat vehicle lamp with current regulation (with schematic)

I was expecting this little filament-style LED lamp to use a simple resistor current limiter. But it uses a neat little linear current regulator instead.

A perfect video for showing how voltage regulators can also be used to regulate current.

The two different styles of filament caught me out. I initially thought it was going to be two identical filaments back to back. The rectifier is a very nice touch. This lamp will work either way round, or even on AC.


If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
