the '57 has original looking signal lamps in grill, however closer look (1) they dont signal, and (2) they only have one wire going into each , all the 3B diagrams seem to show two wires and the 3A having one wire. not sure if the PO was involved yet but I suspect so these single wire lamps only light when I pull the light switch to the pos before the headlights come on, otherwise they are out. from PO there were snowplow lights on the fenders, I refurbished the fenders and tossed the lights ... I still have the L/R live wires curled up under hood which send 12v when signal on ... so, a few questions : ( a ) is it true all 3B's had two wire lamps in grill ? ( b ) how do the two 12v wire lamps behave, are they lit when the headlights are on ? ( c ) should I disconnect the single wire lamps from the fender junction thingy and connect the corresponding snowplow signal hot wire direct to each to get them going , I picked up some #67 12v bulbs but not sure whats in them now. I read the 3B page on 6v to 12v but dont see anything about above , am getting my 3B out of storage and storing it in own garage for winter after all so will be working on above and other things over the winter ![]() thanks in advance Randy |

A.) NO B.) YES C.) I would run a spliter so both are operational just be sure the wires can handle the power load with out burning up first |
3b'ers do it on all 4's

Randy, As already stated, no, the early 3B's did not have the two lead combination parking light/turn signal lamp sockets; (they were parking lamps only and did not come on while the headlights were on). Working on quite a few later model 3B's and CJ 5's that did have the two wire socket, I don't recall any of those from the factory ever working when the headlamps were on, (if the headlights were on, the parking lamps were off). The larger filament in the bulbs lit when the turn indicator lever was switched on. When the CJ5's came out with the side marker lamps in the front fenders and rear side panels, those lamps did activate both when the parking lamps and the headlamps were on. I think it was Don Norris who just recently posted an article (with photos) of converting the single wire lamp to a two wire lamp. Larry S. |

ok this is helpful and making alot more sense now - the park lamps with single wire are correct for 'early' 3B; - the park lamps ON pre headlights and OFF with headlights on also correct; - the PO added signal switch to get L/R lead wires; - to turn my park lights into signals I should be able to unhook them (to be safe) from fender junction and run the L or R lead from signal switch, I only loose park lamps when headlight switch in pre-headlight position; I think I'm going to have fun with a new 12v replacement harness swap in the coming year, at that time I'd like to do Don's clever 1 to 2 wire upgrade. if a 3B had park lamps on with headlights it must be wired differently or the headlight switches are different ? , online shops seem to show only 1 switch for 53-64 3B ? , it would be a nice to have feature with the new harness. |

Randy, Correct (I think, but may be a bit confused with what you wrote). If you disconnect the parking lamp leads from the three post terminal and connect them to the right and left hot leads from the directional switch, then yes, the lamps should come on when you activate the switch, but you'll lose the parking lamp function altogether. If, however, you change out the single filament bulb socket to a double filament 1157 bulb socket, you'd then have both directional signals and parking lamps and the change isn't that hard to perform; (read Don's post on the Home Page and if you do the change, remember to use the heavy filament side of the bulb for the signal leads).
