hello- i have an 1985 200s and when i rev it up the headlight and tailight get really brite and burn out. i was thinking it must be the voltage regulator/rectifier, but it dont have one. (i even checked the wiring diagram on this site). what can it be?

The wrong wattage bulb will cause this. The headlight should be a 55w i think, the tail light i think was something like 10w, basically if you have a lower wattage bulb you have less resistance so the voltage can climb and burn it out. They don't have a regulator, they simply rely on the resistance of the bulbs to regulate. If you wanted you can get an add-on regulator to cure this and also make it more stable. I know i have seen it many times where the tail light will burn out and then the headlight burns out shortly after due to the increase in voltage.
