Google is a thing you know... But yes, there is a front light mod that requires taking a light out of a GBA SP (AGS-001) and soldering it inside the GBC. If you're asking about making the screen brighter without modding it, then no. The GBC screen is not backlit or anything.

I just did a google search and the first thing was using the front light from the ags-001 on the GBC so I didn't know the ags-101 screen worked. Last I heard it didn't, unless that only applies to the original GB.
