Should I be required to change a light bulb for a tenant?

[Kimberly Kesterke]

I wanted to get your thoughts: 

In my lease, I state that any repairs less that $100.00 are the responsibility of the tenant. I have a younger tenant who is asking me to send someone out to change a lightbulb. I sent over a YouTube video link on how they can do it and she said her step stool won't reach. 

Fellow landlords- while still providing great customer service without breaking the bank- how would you handle this??

Thank you,

Kim
