except I don't see a need for the bronze gear. Added expense for questionable benefit. I reused my plastic gears. The pellets are what fail.

Headlight Thumping Noise
My 1993 doesn't get driven much. I took it out yesterday for a short drive. Turned the headlights on. I noticed the left light did not rotate to the full up position as quick as the right one.. When it got to full up it made a thumping noise for about 2 seconds. Then when I turned them off at closing and at fully closed it did it again for about 4 to 8 seconds. Any one ever have this happen if so what was the problem. Your help would be greatly appreciated Thanks Ellis
...Just a note.. I have not turned the headlights on in this car in many years.

Yes common headlight bushings/pucks have failed, is there possibly a white dust under failed light
review this video to see if this is your problem,this guy did a bronze gear conversion which is a little more expensive than just a puck replacement gears themselves rarely fail but I have seen it so bronze is not a bad road to do while your there.

Mark does an excellent job of showing the repair. It's a 4-part video. It helped me in doing both of mine (same problem and sounds as you).
No need for a bronze gear.

Your OEM plastic gears should be fine. It was the earlier model year C4's that ran two plastic gears that benefited from bronze replacement gears, not the single plastic gear/headlight system you have in your '93.
