The hood probably camge with triangular hangers.
Go to the hardware store and pick up several feet of jack chain that has each link bent in an offset figure 8, made of metal that is strong enough to take the weight but thin enough for you to bend by hand with a pair of pliers. Each link can actually be bent open on one side to create a length of chain with a hook on each end.
I recommend using 2 chains, and then one extra one attached to another strong point on the hood in case either of the other attachment points fails. A fallen HID lamp IS a fire hazard.
