Well the bulbs are "kinda" hard to put in, but they only go in one way, so they shouldn't be loose. Did you do the mod to the highs (9005's) or did you go with the stock lows (9006's)? I had the PIAA superwhites (lows) and then installed the Silverstars (highs) and noticed a BIG difference, but I did up the wattage by 9 watts doing this, so thats got something to do with it. If you still have the PIAA bulbs install them in your g/f or wifes ride, thats what I did with my old PIAA bulbs and man, what a differnce over OEM
