Can't adjust headlamps

[Kanto]

I recently changed my low beam bulbs in my S14 and I can see a clear aiming issue. The right headlamp screws don't seem to work in aiming. Is there another way I can aim them, possibly manually? Also it seems the connector to the lamp is loose because the same right light seems to flicker by the vibration from the engine. Is there anyway to fix this?

Thanks I am a noob, but looking to learn:hsdance:

is this zenki? The plastic gears connecting the aiming screws to the headlight aim mechanism often crack/break and need to be replaced. If you want a cheap fix you can remove the linkage and gear and grab the adjustment portion protruding from the headlamp housing with vise grips and turn it that way. If the bulb clip is loose you should be able to unscrew it and bend it back so it has the correct tension on the bulb.
