So is there a real difference in the 4651 and 4656 sealed beam headlights? I scored 4 4651 blubs at a mega sale at work and I later found out that the 4651 are high beams and the 4656 is the low beam on 1986 Olds Cutty. Will it make a differance if I install all 4 as 4656? Am I going to be blinding people like I have the high beams on if I use the 4651's as low beams? any body have any info?
