Handmade LED Stop Parking Turn signal

There was absolutely nothing to do in winter, but at the same time I always have a desire to advance my bike.
There was a desire to replace in the rear lights of the stop signal lamps with LEDs.
I disassembled the stop signal about five times and wondered how and what to put inside.
Finally it was decided to collect an additional separate informative headlight from scratch.
I found the necessary scheme on the Internet:

Here are purchased and checked by me details:

stabilizer KR1158EN
capacitor 10mf 50v
resistor 120 ohms
diodes 3v 20mA

Why did I make things so complicated?
Diodes do not like power surges in the board network.
The capacitor smooths the ripple, and the stabilizer balances the voltage.
Having checked the scheme in work, I bought the necessary number of parts and everything necessary. Long time wandered around the city trying to find the right ceiling.
Not exactly what I wanted, but with a white glass. I cut out a suitable circuit.

Along the way, I started working with illumination of the device panel, but this is another story...
