as already said, those blue ones are JUNK. i have tried several different sets, and they are ALL a waste of money.
my wife's car is a 94 concorde, and those lights were so bad chrysler "upgraded" them in 95 or 96. the "upgrade" light housings consisted of fluted lens instead of a mostly clear lens. they STILL were not very good lights. i tried some LEDs last year in a new set of genuine mopar light assemblies, and it was a definite improvement. however, the LEDs are a tad tough to aim [in my opinion] because of their beam pattern. these were the bulbs with the cooling fans and adapter resistors. if it makes any difference.
we both don't drive after dark much any more, so this may not mean anything to anyone.
