2001 corolla LED Light Bar

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 quick update i was able to achieve what i needed i have uploaded the diagram as well i used DPDT switch "Sea Dog 420258-1"
