There is a service bulletin 04-08-42-001 about this, apparently GM considers
this a normal condition:

"Information on Intermittent Dimming (Flickering) of Headlamps and/or
Instrument Panel Lighting -- Normal Characteristic/No Service Required
2000-2004 Saturn L-Series Vehicles

The purpose of this bulletin is to inform Saturn Retailers of normal
headlamp and instrument panel illumination characteristics.

Customers may comment on sporadic dimming (flickering) of the headlamps
and/or instrument cluster illumination. The flickering may occur
intermittently as a result of transient current loads on the electrical
system during normal vehicle operation; however, at no time do the headlamps
turn completely off. This is considered a normal operating characteristic.

No service is required for this condition."
