indicator bulbs codes/designation
 

HI all, pretty feeble question here so apologies , but am trying to order a set of indicator bulbs for up front, and have found a set pretty cheap but there is no indication if the pins are offset as they should be, checked high and low on web but 0 , what codes should the bulbs have? I am sure about the PY21W part but online you have PY21W BAU15 PY21W 581, which code would specify if the bulbs has offset or pins that are directly oppostie each other...... here is the link to site i found the bulbs on

Halfords | Bosch (581) Car Indicator Bulbs x 2

indicator bulbs on E53 are off-set 150 degree. 12V & 21W. Bulb code is 7507.
