i'm thinking about re-aiming my headlights and i'm lazy and dont wanna go out and do out. i was just going to aim them using my garage door as my guide.

i'm wondering how long (if at all) i can keep my headlights on without turning the engine on (dont want to kill myself). any insight is appreciated.

 

you'll be fine to aim your headlights.

 

so bout 10-20 minutes and my electrical system will be fine?

 

Yes, depend upon how old your battery is, even UP to an hour... although I wouldn't recommend it.

10-20 is fine

 

Yeah it'll be fine. I usually have my stereo bumping for over an hour with no problem.

 

it will be fine, doesnt take more that 10min to adjust the headlights, just turn on the car after your finished for about a minute or so....

 

I have to take my lights out to aim them or put new bulbs in.

I got pretty damn good at taking off my front bumper
