It has never been stated what made Rudolph's nose glow red. Rudolph just happened to be born with a red nose.

They can't glow. Reindeer noses can't glow, it's impossable to glow. Only fireflies can glow because of science.
He got laughed at and wasn't allowed to play reindeer games.
Use a bit of bronzer on your forehead, nose, and chin to create a dewy, sun-kissed glow.
It glows from "being very shiny."
If by 'roudolph' you mean Rudolph as in Rudolph the red nose reindeer, I can answer this question. As a matter of fact the only evidence to suggest that Rudolph, the fictional Christmas character, actually has a father, is that Santa Clause is Rudolphs owner. Therefore, this determines the question 'who is Rudolph's dad - Rudolphs dad is Santa Clause.
Fireflies make their bellies glow by combining certain chemicals that make a "glow" in their bellies. This glow is used to communicate to other fireflies.

From the StoryI don't believe there is a reason given in the story for what caused Rudolf's nose to be red and glow. It just started glowing one day. The Lighter, Creative SideBecause Prancer (his father) accidentally veered off from the rest of the group while Santa was in Russia, and came too close to the Chernobyl site. Therefore his son inherited a genetic mutation caused by the radiation there. And TADA! we have, Rudolphs' nose! LOL, I don't know, it's just fiction. Use your imagination. It's fun! :D
