I just took this picture of mine. It appears to be some type of bracket.

Yes. The thing in the middle between the two bolts appears to be clear so it may be a dim light.

This is correct. I replaced the bulb in mine and it works, but doesnt provide enough light for any good.

Re: Under dash hole

It puts off just enough light to make a man wonder "Where is that light coming from?"

I've only owned my IROC since February and I've never driven it at night so I've never seen this dim light doing its thing. The car is currently "under the knife" but I'll have to check it out once the car is back on the road.

Re: Under dash hole

There's a bracket on top to hold a 74 bulb, it has the j nuts for the cover with a hole in it.
