Yes I have the 1157 bulbs.
I have 1 wire for 'right turn/brake' and 1 wire for 'left turn/brake'.
I have 1 wire for 'right tail light' and 1 wire for 'left tail light'.
Each socket only has 2 wires, hot and ground.... I have 4 sockets, 4 lights on the rear (not counting the side markers).
I was just going to put 1 wire to each socket/bulb, then do the ground wires to all.
How do I select which 1 of the 2 filiments light up in the bulb??
I personally want to do this: (1)(2) ----------------- (3)(4)
1 & 4 = brake/turn lights
2 $ 3 = park/tail lights
Is that possible with my sockets if I buy single filiment bulbs? Will this interfere with the turn signals?
Thanks again Doc
