Phenol slowly oxidizes on exposure to air and turns pink in color. At first, quinone (p-benzoquinone) is formed which again reacts with phenol to form a polymerized product phenoquinone which is red in color.

There has been research on the oxidation of phenol like wet-air oxidation and catalytic oxidation but those are out of scope.
Oxidation of phenol using light has been studied using UV/$\ce{H2O2}$/ozone system. From this paper:
The photolysis with 253.7 nm radiation practically does not degrade
phenol. But the combination UV/ozone gave better results than the
using only ozone. In the degradation of phenol using ozone there are
two main reactions: the direct reaction of ozone with phenol and its
products and the reaction of the hydroxyl radical generated. Some
intermediate products as benzoquinone, catechol and hydroquinone were
detected during the degradation of phenol.

So, yes. Necessary precaution are taken such as phenol are kept at brown bottles.

I think solid phenol is less prone to oxidation due to air/light than liquid/azeotropic phenol because of $\ce{\pi}$ stacking, efficient packing of crystals and hydrogen bonding leading to stability.
