He meant changing the lights like Flashing Neons just like in Need For Speed Underground 2.

I guess you need SetTimerEx (if using playerid parameters) and create a random function to your own maxium value.

then switch the random.

then delete the old neon and replace it with new one everytime the timer called.

Since i don't know about this flashing neon. I don't think the tip i give will work.
