My 2012 GT Premium
So I didn't like how my s197 can factory with LED Tailights but HID headlights and incandescence bulbs for everything else, so I upgraded all the incandescence bulbs to LED. Last week I replaced all the 194's with LED, Marker Lights & map lights and there was no problems. Yesterday I replaced the 3157a's in the front and the 912's in the reverse lights. Initially everything worked great but then night came and my headlights came on and suddenly my turn signals started flashing quickly. When I turn the lights off they work normally, and even with the headlights on the hazards work normally. I quick google search produced a failing turn flasher but with the original bulbs back in everything works normally.
Did I get the wrong bulbs? the local parts store looked it up and said that it takes 3157a for the front turns but when I just did a quick google search their own website says 3457NA. the bulbs I bought are replacements for 3157 3156 3057 4157 but not the 3457NA.
Thanks for any replies and information.
Edit: From what I can see the voltages are the same on the bulbs, but the amperage and wattages are different, Normal incandescence run at 3157A 25.2/7.1 watts 2.1/.59 amps while the 3457 is 28.16/8.26 watts and 2.23/.59 amps. I am not sure if this makes the diffference or not, the LEDs I put in operate at 5.4 watts and will operate at any voltage between 9-30v. no amperage rating that I can find tho. The companies official page says that it is a direct replacement for the 3457 also, but I might needs a load resister or decode to use them as turn signals, what are those and where do I find them?
