dear fellows i have 2001 model corolla with crystal head lights(probably they are taiwnese)

don't know if there were originally the crystal lights or the simple.can anyone tell me the truth?

my issue is that they don't throw the light straight properly. the light gets diffracted specially the right one and the left one stays on my bumper.

i have adjusted both many times but after 2 to 3 weeks again they replace their positions as before.
i also have opened the lights from workshop but they are still the same.

can anyone please me guide me for the head lights as i wanted to replace them.

which one should i buy and from where(islamabad and rawalpindi)
