basically, you tap the wires so that when the low beam or high beam lights go on, you still got other lights that you want on and make them stay on

sorry, hard to describe

eg, oem = 2 bulb design low beam & high beam in one

when high beam goes on, low beam goes off.....

now you want to use your 4 bulb angel eyes or whatever rice shit you bought and make it work the way you want it, which is to have all 4 bulbs on when you turn on the high beam.

use a relay to tap into the high beam wires as a signal, then get the relay to power the low beams when the high beams are on
