Pridor does not produce this much vibrations, there is may be nuts and bolts are loose of bike. if you are feeling vibration in feet than gets its frame engine bolts tightened and also there are rubbers in swing arm axle if they have worn out bike will vibration but bike is not that much driven so they may be ok.
and yeah main thing if you visit bad mechanic and bike is not properly tuned this can cause vibrations as engine struggles tight valves cause the engine to vibrate. Problem here is that most of the mechanics are idiot complete idiot.
Pridor headlight nothing much you can do about it has poor headlight. I suggest you to call helpline number of Atlas Honda register your voice of complain as well. Alternate is installing separate led lights or led bulb. But i don't have experience of these things as i have never tried these kinda alteration with my bikes
