spec,
Check pin 8.
Also the required switching voltage levels for the 555 Trig pin #2

Hy Eric,
Nothing has been checked- it's just a concept which I did in a rush.
You didn't like my innovative use of pin 8
Thx for info anyway.

Hy Eric,hi spec.
I deleted my first post as I had missed the 12V to 5V change in 12V to 5V.
If the OP is using a MCU as the signal source at say 5V, it would be more practical to use the MCU output pin to drive the MOSFET.
or
just use the 555 as an Astable to drive the MOSFET.

spec,
I see you have changed the 55r power to 5v, so what is the purpose of the 555.?

Hy Eric,spec,
A MCU pin set as an Output can easily actively source/sink the nC charge on the N MOSFET Gate.
An advantage is that the Gate drive could be PWM, enabling brightness control, if required.
