The power of the light bulb, and as a consequence the intensity of the light bulb, remains constant, so the longer the light bulb is at a certain moment, the more energy comes to the eye.

In harmonic motion, the position of the light bulb is described by the expression
$$ x(t) = x_0 \sin\omega t $$
From here, the speed value changes as
−
$$ v(t) = \dot{x}(t) =\omega\cdot x_0\cos\omega t $$
+
$$ v(t) = \dot{x}(t) =\omega\cdot x_0\cos\omega t $$
The lower the speed, the more time it takes for the light bulb to cover equal intervals of time.
$$ v\sim\frac{1}{\Delta t}$$
Thus, when the speed of the light bulb during harmonic motion is minimal, the energy perceived by the eye becomes greater.
$$ W\sim\frac{1}{v}$$
Thus, the bulb appears brighter in places where its speed is minimal, i.e. at its extreme points.
