Anyone know if i can put AP1 headlights onto a AP2 with just buying the headlight unit? Want to swap over cs AP1 headlights look dope to me

 

You need AP1 ballasts also.

Besides that, you may need JDM parking light sockets, assuming your AP2 is USDM and you buy JDM AP1 headlights.

 

I just installed JDM AP1 lights on my 05. You will need JDM turn signal sockets.

All of the other bulbs are plug and play, but they use different ballasts. I designed and 3D printed a bracket to mount the AP2 ballast to the AP1 headlights.
