1156 to 1157 light bulb socket swap
I want to convert my turn signals from 1156 (single filament) to 1157 (dual filament)
You might be scratching your head in confusion as to why i would want to do this.
I want switchback turn signal LED's.
If you don't know what they are well, look it up, they have them on diode dynamics.
Just wondering how hard this would be but i do not want to cut factory wires, so if anyone has swapped sockets before give me a shout please and thank you.

Okay... so, your current 1156 socket has two wires, right? A positive (activated by turn signal) and a negative?
Grab a 1157 socket from a junk yard. Cut the wires so you have plenty to tap into later. Find out here from other members which of the three wires is the constant power and which is the intermittent (turn signal flash) wire. Blacktibs might remember; he had a DIY that told which wire to tap into for angel eye headlights.
Anyways...
The power wire going to the 1156 socket will be wired into your 1157 intermittent wire. This should be activated by the turn signal.
The negative wire going to the 1156 socket will be wired to the negative in the 1157.
For the "constant" power wire on the 1157, you need to tap into your headlights so it has power every time your headlights are on.
I just thought this through in my head. I've never done it before but it makes complete sense. I'd like for someone else to verify my ideas are correct.

Help? In what way? This will just be connecting three wires. Get wire taps for tapping into the headlight so you don't have to cut that wire.
You'll have the socket but need to find a way to make it stay connected to the unit. The socket you buy won't have the tabs to keep it in the assembly. Even grabbing one from a donor car might not have the proper tab positions to hold snug.

I don't see why. I'm not an expert in that area though.

I took the one turn signal out today and turned it out...obviously it went into hyperblink mode so i think will need the load resistors due to the extremely low current draw of the LED bulb. its gonna be rough.
