Switches in my 58 Fleet

[hogfarm]

I have just about got the wiring done on my 58,couple problems.I bought a headlight and an ignition switch from LMC.
1.Headlight switch-when I turn parking lights they work fine,when I turn on headlights,headlights work fine but parking lights turn off.Is this normal,are the wired wrong or is the switch not working
2. The ignition switch,turn to the left there is no power at the ACC post,turn to the right every post has power,and the key will not stay in,comes out in any position.
3. I called LMC last Saturday and they were no help at all,told me the switch were for a 55-57 not for my truck...55-59 should be the same.
