Its ok. When I had the city lights I used a small drill bit to make a hole for the small led I had put in it. Only problem is if u go to far in you will pop a plastic lens cover off and have to open the whole headlight to put the plastic cover back on. Happened to me was so aggravated lol. I suggest doing this if you plan on Joey modding ur headlights as you will have the headlight torn apart already so it will make the job easier to do.
How did you get those holden parts?
