Why is my Game Boy Advance SP screen so dark?

Your Game Boy Advance SP screen is dark because the original AGS-001 model has a frontlight, not a bright backlight, making it dim in bright rooms, unlike the later AGS-101 model; issues could also stem from a dying battery, a dirty screen, or a faulty internal component like a capacitor or loose ribbon cable. You can try adjusting the built-in brightness (if it's a later model or modded) or check the battery, but the most effective fix for a truly dark screen is a modern IPS screen mod.
