    1997 BMW 740 IL*******NEED HELP ASAP

    Ok so i was played for a vehicle and ended up with a 1997 BMW 740 IL thats a lemon...Anyway today I went to the junk yard to get a few sockets for the tailights because I noticed alot of them was missing...I put brand new bulbs in them and they work...I noticed i did not have any brake lights at all but i have parking lights...SO i placed a socket into the brake light area and it did not work so i removed one of the parking lights and placed it in the brake light area and still no luck...So i take the thing to a mechanic and he tells me that i need a circuit board for both tailights for the brake lights...So a good friend of mine who is a mechanic put the sockets in place and the left brake light worked but the right brake light would not work...Im confused because i was told i need a circuit board but yet I have 1 brake light that actually works now so my question is....Do you think it may be corosion around the socket brackets? or do you think i really need a circuit board...But mind i was told that i need it for both but now 1 is working...Any suggestions would be greatly appreciated seriously...Thanks for the help

    In the older light housings the contact bars on

    the circuit board get burned spots. Three solutions, 1. rotate the bulb socket about 5 degrees to get a clean spot; 2. Put a drop of solder on the burned spot on the contact bar; 3. buy a set of Euro style crystal tail lights (what I did). Lot of info on the other board.
