Every two seconds driving home I got the beep beep beep. I was ready to drive the car off a bridge seriously.

The bulb lights when you push on it so I'm guessing loose connection. Problem is the screws are rusted in and I can't get it out. Any ideas? Please help me!

Use little more power and rip off the screw... as I did...I think there is no another way...

thanks yeah, One screw head snapped off but the other one won't give so I'll have to use a chisel or something to get it off. Once the heads are off though how can you replace the screw that's left in there? Or am I just going to have to duct tape it back on :S

Silicone works like a dream. In addition it is watertight.

no need to replace the rest of the screw, the lights will hold there without problem, when you push its back.
And you can use silicone for sure as Morty wrote.
