New to the site and most definitely a neophyte when it comes to auto electronics. After replacing the drivers side headlamp assembly 6 mos ago ($700), come out today to find the same lamp out. R) side still works. Seems that it is on a differnt fuse. My local service guy thinks it may be the SJB. Dealer no longer carries the part so aftermarket then. ($450 parts and labor) My question is: Can this be bypassed? pros/cons Thanks in advance for any guidance you can provide. JG
