Hi,
I recently bought double contact led bulbs to change it on my vehicle. when i removed the old bulbs the contacts were aligned in a different way to the one i bought. the old one had the double contacts facing along the notches, where as the bulbs i bought the double contacts are facing perpendicular to the notches. any clues what type of bulbs are these. the one i purchased is BA15D. Thank you,
Imran
