This is a single lamp only (no switch, no relay, no wiring harness) If you need two lamps, as well as a wiring harness, switch & relay, you might want to look at this item- http://www.amazon.com/HELLA-12-Volt-55-Watt-Halogen-Driving/dp/B0002MA4T8/ref=pd_sim_auto_1

I can't answer that as I returned the unit without even opening the box. Reason being I was given a new unit as a gift. So had no use for two units.

I would start with just one. You can always add a second later, but I would be surprised if you need a second one.

Yes, count to 2 and it's on. Not a problem once you get used to it. Good unit.

I would get 2 units. Even if one does the job, this is such a wonderful product that you are sure to find another place where you want to put one.

That is a great question. I cannot answer it with any certainty as I only purchased the one unit. A call to the manufacturer would be the best route for a correct answer.

my daughter uses this so I don't have it with me to look at it, but I believe it is one of each. (1 port is 2a, 1 port is 1a).

2, unless you double up. But then you'd blow a fuse like I did. So the answer is 2

The unit I have has only one input and three outputs. So if I am understanding you correctly I would say no. You are saying "both" inputs which means two to me and the unit only has one input. I hope this helps.

A single unit is sufficient, but a little higher would be better. I added a 2x4 to my unit and found it much better.

I'm pretty sure it was just one... I ordered two anyway. They are well built.

Even though it SAYS two, it only comes with one. I haven't tried to move it from side to side yet.

2 separate units, each with 1 screen. 1 unit is only a screen the other unit is a little bigger- it opens so the dvd can be inserted.

2U is correct, although it is a bit (very tiny bit) out of spec, so if you sandwich it between two 1U units (that go edge-to-edge) you might have some issues.

One unit should be fine..but without knowing your radon levels and other factors noone can provide you a concrete answer
