Pretty much as the title says. I want to get his headlights out so I can paint under them; I've managed to get the left one out with no problem, but the right one is being a lot more stubborn; it's difficult to know where to attack. Has anyone managed to circumvent a simlilar problem?

Just to avoid any confusion, yes, I'm pushing it from underneath, having removed the underside bumper panels.

 

you need to check the underneath of the car's bonnet (or hood if american). you should see a peg that is the back of the headlight, tap that out with something and you should have removed said light

 

That's exactly what I'm doing. As I said, it got the left light out with no bother, but the right one's refusing to budge for some reason.
I'll have to give it another go in a while.
