Light Bar & DVD Questions

Hi PhilD & HummerH2

The discussion on the lights has been great - I have ordered the roof lights (as stated - I have the grille lights already) I want to tell the Dealer to wire so that I can used both. It sounds like the dealer (according to your discussion) will not bypass GM standards. How difficult is it for me to wire the grille light to the headlamps high beam? Secondly, if the dealer wires according to standards - if I turn on both roof and grille at the same time (two switches) will the two grille and only two (of four) roof lamps be active? Lastly, is there a relay that is not in use that the roof lamps can use? Finally, what is the MidBec - and how can I talk to the dealer about finding a solution regarding the MidBec?

Thanks
