Yes the bulbs are matched the same ones manual calls out --all bulbs are new and matched ==tail lights == brake lights == head lights the center brake light is correct and new and works --The bulb fail light is on allll the time when engine is running does not matter if head lights are on/off although it does correctly dim with head lights on -- parking light on/off-- brake light on/off --it is always on. Acts like a stuck relay does this system use a relay or some kind of black majic logic circuit? Do not have a good print of electrical system. Some day this problem will be resolved when the dash [bulb out] bulb burns out, until then this has become an anal problem for me! Thanks Steve
