Jeepcom23 Posted November 9, 2008 Share Posted November 9, 2008 ok I put new bulbs in, my front blinker. So now my left blinker makes my parking lights blink along with the gauge cluster lights and lights on my ac/heater control panel, and when I turn my headlights on my left blinker won't blink it just stays a solid green arrow inside. Also does all of this when I hit my brakes. PLEASE HELP!! Link to comment Share on other sites More sharing options...
mvusse Posted November 9, 2008 Share Posted November 9, 2008 Check the ground at your front and rear bulbs. It sounds like there's no ground just about anywhere. Link to comment Share on other sites More sharing options...

garmj Posted November 10, 2008 Share Posted November 10, 2008 What number bulb did you use? Sounds like you used a 1156 instead of a 1157 they tend to short the tail lites and turn signals together and makeall sort of weird crap happen. Link to comment Share on other sites More sharing options...

Hmmm... the book (for choosing light bulbs) at both the local NAPA and the Advance Auto both indicate that 1157 and 1156 can be used interchangeably in our vehicles.

carnuck Posted November 15, 2008 Share Posted November 15, 2008 2057 and 1157 can be used interchangeably. 1156 is used in the tail lights, but only for backup lights. Link to comment Share on other sites More sharing options...

Thats good to know, 'cause I just bought some new bulbs (you didn't think I just browsed the books, did you?) and I don't want to create new problems... :cheers: Link to comment Share on other sites More sharing options...
mvusse Posted November 15, 2008 Share Posted November 15, 2008 If I remember correctly, 2057 and 1157 are two filament bulbs, with two contacts on the bottom; kinda like two bulbs in one. A 1156 is a single filament bulb with a single contact on the bottom. Link to comment Share on other sites More sharing options...

I don't think the book says they can be used interchangeably. The 1157 is a 2-filament bulb, used for taillights/brakelights in the MJ and for taillights/turn signals in the XJ. The 1156 only has one filament (and one contact on the base) and is used, as noted, for backup lights. Link to comment Share on other sites More sharing options...
carnuck Posted November 20, 2008 Share Posted November 20, 2008 I just had a bad 1157 in my '81 Chev C20 pickup (wish I'd taken a pic of the bulb before I tossed it) It somehow jumpered between both wires and when my brakes were applied, all my park and dash lights (ones that still worked anyways) came on and my RH turn signal didn't work with the headlights on (dash light for the signal was always on too) Link to comment Share on other sites More sharing options...
jaekl Posted November 20, 2008 Share Posted November 20, 2008 One point about the double filament bulbs. They have different polarity. If you use the wrong one the turn signal/ brake will be dull and the parking/tail light will be bright. Tell me why it couldn't be standardized.

carnuck Posted November 20, 2008 Share Posted November 20, 2008 I haven't seen one do that yet. The pins are stepped to avoid this. (I HAVE seen people force a bulb in 180 degrees off!) Link to comment Share on other sites More sharing options...
garmj Posted November 21, 2008 Share Posted November 21, 2008 Working on cars for 35 years and on used cars for 25 you see a lot of strange things, most common are people who use the wrong bulb because it FITS. I have seen filaments short together but very seldom, another common thing especially on trucks are the wiring GENIUSES who attempt to wire trailer harnesses. But I can't honestly I have seen a 1157 put in 180 out. Link to comment Share on other sites More sharing options...
mvusse Posted November 21, 2008 Share Posted November 21, 2008 I have seen an 1157 put in 180 degrees off, and have done it myself also. Plastic sockets are quite flexible when it's 90 degrees outside. After replacing a bad socket with one listed for a Ford from Advance, I connected black to black, brown to brown and blue to blue. Turns out Ford and AMC use opposite color coding, so for a week or so I had the bulb in rotated 180 degrees purposely, until I cut the wires and hooked them up brown to blue and blue to brown.
