点く (つく, tsuku) — to be lit — is a godan verb ending in く: ついて (te-form), ついた (past), つかない (negative), つきます (polite).
It is usually written in kana: つく rather than 点く. It also means to catch fire; to ignite.
How つく conjugates · godan く-verb
Only the last kana changes: く becomes か, き, け or こ.
Which one depends on the ending. The five are one line of the hiragana chart — same consonant, vowels あ・い・う・え・お — and everything before that kana never changes.
The て and た forms are the only two that don't follow this pattern. Every く- and ぐ-verb changes the same way there; only 行く is different.
