Side Lights and other questions

[John Ganton]

I hope this forum isnt just for answers because what I have are questions.
The side and rear lights on my HUP look in good condition but they are seized. They shrug off penetrating oil and I'm afraid to use heat. What's the best way to disassemble them?
My emergency brake cables are finally free. What is the best way to lubricate them so they dont seize again?
I have aquired a Chev air compessor. Is it appropriate to mount this on a HUP.
