i jus converted to a 1997 upgrade, and the tail lights i just recieved currently has 7440 bulbs in the reverse, signal, and brake lights. on sylvania's wesbite it says to use 7443 on 2/3 of those light sockets? i am confused as to which size to use? also the top strip of running lights with the 2-small bulbs look to be 194s but i am not sure. can anyone confirm with me the size of these bulbs? i need bulbs for both sides. and before the search police comes i searched and found various numbers. thanks in advance!
