SOURCE: DRL and High Beam do not work right on Honda Accord EX 1998

Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights.
Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
