The lights on my 72 superbug are dim on one side. I've redone the earth, and ran new wires for the side, dipped and beam lights from the fuse box to the light itself. the light illuminates but slowly, and dimly. It looks like an earth problem, but I've even tried earthing the bulb directly back to the battery to elimate this.

Any ideas??

Thanks

Could it be the bulb holder not making contact with the bulb.

Is the holder getting warm?

Could it be that the reflector is just lost its brightnes? - as in its not the bulb but the light atoms and they arent reflecting well?

Is the wire join a good one at the bulb holder?

What happens if you swap from left to right ? Does the same side stay dull or does it swap to the other side ?

how are the bulbs are they black on the glass....
