Hi All, i have recently purchased Lexus LS460 2007 and looking to replace the bulbs such as low beam, high beam and front fog light ones. I have been advised by the shop that the connection for xenon dipped beam is D4S and hence purchased osram night breaker x 2. I have checked at the other shop and it shows the connection as D2R for the xenon dipped beam.... Not sure what to do, how do i find out which connection it is? Thank you in advance, guys!
