yea I was just gonna say galls. Im by no means an expert on this, but I installed some in a friends car (he is on the local ambulance cors., I wouldn't get this if you dont have a reason to) and they seemed like very high quality and its actually a real system like with a control box which can control a certain number of strobes (his was 6) and then once you have that box you just get the wires and strobes themselves.
