4x4 light won't come on

So I was out of roading and I must have flung up a rock or
something which then hit 1 of the vacuum lines that locks in the
hubs. So that point I had no 4 wheel drive and my light wouldn't
come on when I put it in. I got my vacuum lines fixed and the 4
wheel drive seems to be working at least the 4 low does the 4 high
I not sure it seems to go in but hard to tell without jacking it up
however my light still doesn't come on just wondering if anybody
has any advice or ideas I really doubt that it's just the dash light
bulb that went bad
