Why would a 93 Cavalier RS in which you recently replaced a headlight bulb and both lights worked now only the day time running lights work and brights turn on when the lever is held?

Most likely cause of this malfunction is a non-functioning headlight switch assembly. As the switch wears the springs that force the contacts from the dimmer switch to the electrical contacts that ground the signals for the lights wear as well and thus stop functioning correctly. Holding the switch back allows the contact to be "forced" so the lights will work. The headlight part of the switch has a similar problem there are springs controlling the three separate functions; "Off" (Daytime running lights) "Parking lights on" (Everything but headlights) and "Headlights on" (All lights on). You may be able to open up the switch and clean the contacts and get away with that for a while but your best bet is to find a car at the wreckers with low mileage and take it's switch, or pay the high price for a brand new one off GM.

I also own a 97 Ram 1500. Recently my headlights would go out when I tilted the steering wheel into the down position. I replaced the multi-switch (wipers, brights, turn signal) and the problem was solved.

could be headlight fuse or headlight switch.

Yes you will need a headlight replacement even if it is only the brights that aren't working. There are times when you need your bright lights so don't delay in getting a replacement.

have you replaced the dimmer switch? if not that may be the problem. I had the same problem in reverse( brights worked but headlights didn't) water damaged the dimmer switch on the steering column once I replaced it all was good.
