I know that in order to change bulbs you need to take the whole headlight unit out but when you put it back in to you need to realign and reaim the headlights?

 

thats exactly what u have to do, its a bitch of a job, enjoy!

 

what u mean realign them? every time i have taken mine out and put them back on i still have a straight line on my garage door.. huh

 

yeah no need to re-aim them ur not touching the aiming piece just the bulb

 

You do need to take out the headlight to change the bulbs. When you reinstall the headlight, You will not have to re-align them. Good Luck!

 

you have to remove the whole headlight assembly just to change a bulb? really? i changed the bulbs in my '91 z24, and all i had to do was remove the bulbs, took maybe 10 minutes, and 9 minutes was trying to figure out how to take the bulb out without breaking anything cause i'd never done it before!
