Slightly dimming headlights

Slightly dimming headlights
My 98 LX has, from when it was new, a case of dimming headlights. At night you can notice that the headlights (both of them) slightly dim momentarily and then are back to normal. This seems to happen pretty regularly. Like every minute maybe or so (varies). It's my wife's car and she has seen it more than me. It doesn't dim drastically only slightly but if you're paying attention it is noticable. Could this be an alternator or voltage regulator problem and could this be causing other problems too. Have been getting code 41 (primary oxygen sensor-heater circuit malfunction). Can reset the ECU and the CEL goes off for a few days then back on. On a another post it was suggested that the alternator acting up could possibly be causing the sensor-heater circuitry to malfunction, deteriorate or something. Whatcha think? Thanks for any info.
