Do you mean parking lights or brake lights. If brake lights stay on, you just need to adjust the switch under the pedal. The problem with these conversions is that the pedal is farther down and thus, makes contact with the switch. I had this problem when I did the swap. Sorry if I anwered something other than what you were asking.

It's pretty Simple. Look up under the dash at the brake pedal and you will see a white plastic switch with an adjusting nut. Just back it off a bit. More than likely you booster isn't letting the pedal back quite as much as without. Which also leads me to think about your linkage adjustment. You might need to adjust the plunger rod on the master cylinder, as the brakes might not be comming all the way back.
Good luck

well heres the thing my mechanic who happens to be my boss helped me do it. when he was under the dash he noticed a yellow wire had been fused into the switch for the brake pedal he asked me what if was for and the wire leads to my deck and says back up on it
so from what we can figure it has something to do with that and ya its the brake lights and park lights we even adjusted like u said and it works for a while but not too long maybe needs to be adjusted more
