Hi i have 2001 corolla and i have installed 24inch led  light bar comes on when you cycle the high beams on and cuts off when you cycle them off  my current wiring is below,

Using a standard 30 amp 4 pin relay, the wiring is as follows:
*Pin 30 goes right to the battery with a 15 amp fuse in-line
*Pin 87 goes to the 12+ input of the LED light bar
*Pins 85 and 86 go directly to the wires in the plug for the high beam light bulb. Polarization doesn't matter with these wires (doesn't matter which is + and which is - either way they're just completing the circuit and tripping the relay)
Then just ground the - wire on the LED light bar and that is it, they kick on with the high beams.
that is what i am trying to achieve now
I want to be able to have the bar;
- Come on automatically when the high beams are flicked on
- Be able to turn the bar on and off while high beams are engaged for in town driving
- On a switch so that it can come on independently when the high beams are off 
can someone advice me how to make this happen?

just run two relays, one triggered by the high beams and one triggered by a switch in the cabin.
