What u are getting confused about is the model of the bulbs. I'll try and explain. Right, 382 means, the pins on the base sit dead opposite each other ok, and 581 if you look on your bulb, they are not dead facing each other (should be like a slight V shape), this means they are offset. So i think they front ones on our cars are the offset one, which is the 581. Go take out your bulb, and have a look and see if they are like this when u look at the base, look at the pins sticking out http://cgi.ebay.co.uk/CHROME-SILVER-581-BA...1QQcmdZViewItem Hope you understand what iam on about.
