I noticed when my low beams are on that there are little bits of dust on the lense. not very much but enough for me to notice.

Oh and the reason for it is because I painted the inside of them black and forgot to mask the lense when they were sitting in my house... oops

can you like take them out and use an air hose to blow them out or would that cause damage to anything?

 

I dont know if you guys can see it but yea..

 

I seem to have a bit too, but if you find yours eccessive it might be fumes from the part you painted that sticked on the glass from the heat

 

Yea like I said it isnt to bad though so im not gonna worry about it. you can only see it when the lights are on lol.

 

Out-gassing from the drying paint seems like the most likely explanation. Painted items need to be left to dry for up to a week to ensure all of the solvent has evaporated.

 

Anything I can do or should I just leave them be?

 

Leave it be I would say, what ever fumes that had to evaporate must have done so already, so I wouldnt bother

Edit: or re-open the lens and buff the lens from the inside lol

 

Yeah, the only thing you can do is remove the lense and clean it very thoroughly.
