Can't blink a LED using SPI interface on Raspberry Pi v3

As a part of my PoC project, I’m using single 5050 LED made by Adafruit. I wired it like this (LED – RPi):

• DI (Data Input) – SPI0 MOSI
• CI (Clock Input) – SPI0 SCLK
• GND (Ground) – GND
• VCC (5V) – 5V PWR

SPI is, as far as I’m concerned, is enabled – I’ve done it using raspi-config and also added required line in /boot/config.txt manually (I’m talking bout param=spi=on)

Output of lsmod | grep spi* command:

spidev                 16384  0
spi_bcm2835            16384  0

And ls -la /dev/spi*:

crw-rw---- 1 root spi 153, 0 Jul 29 19:17 /dev/spidev0.0
crw-rw---- 1 root spi 153, 1 Jul 29 19:17 /dev/spidev0.1

To try out my setup, I’ve launched python interpreter and wrote:

import spidev
spi = spidev.SpiDev()
spi.open(0, 1)
resp = spi.xfer([0x00, 0x00, 0x00, 0x00])
resp = spi.xfer([0xFF, 0xFF, 0xFF, 0xFF])

And nothing happened. What’s important, I want to achieve my goal using Python. SpiDev module was installed at the time of the trials. For now, I’m only interested in simple blink, after this is reached, I can go further with modulation or frequency settings.
