Uh, but if he wants to have a Blue Bulb.. on standard dials.. no change of fronts or anything, he cant.. because either way, they ALL shine orange.. the only way to get rid, is if he changes the dial fronts.. to say, White or something.
So why do we care how Renault did it - you cant do it, without changing something on them..
Either getting new dial fronts.. or getting rid of the orange backing, like, I, uh, said.
