I have lots of little specs on my headlights. I'm not sure if there tiny holes in the plastic or dirt laying on top. What do you use to get rid of it?

 

try a claybar first to see if it's actually dirt. It's probably rock chips in the headlight. You can use some plastic products for that like Mequiars PlastX or if you want to be very daring you can wetsand the lights (i'm gonna do this soon)

 

Best stuff for plastics, such as headlight covers, is this!

I have used plexus and it rocks! I would reccomend trying that. It can be hard to find in stores though
