Installing switchback/dual color LEDs for turn signals. Need help!
Hello,
I am installing these dual color LEDs for my turn signals.
TYPE 2 DUAL COLOR CHANGING 6K WHITE AMBER SWITCHBACK 60 TURN SIGNAL BULBS 1157 2057 | 1 PAIR
I need to install a load resistor to lower the voltage to the LEDs. In order to do this, the resistor splices the ground and the turn signal wires.
My question is, since there are three wires, how do I identify the two that I need? Thanks a lot.

those look plug and play to me.
every LED bulb I ever bought that was already in a housing I just popped them in and they worked fine.
Nowhere that I could see on the specs for those bulbs does it say you need to wire in a resistor.
Resistors are normally needed for when you are using raw LEDs and soldering them to a circuit board.

V-leds led bulbs generally already have resistors installed in them. At some other Honda forums, a lot of people buy V-leds bulb. That bulb should be plug and play. On certain of V-leds better bulbs (e.g., license plate bulbs, turn signals, etc.) they also use bridge rectifiers, etc. unlike some other sellers.

Hi guys
1999 Honda Accord. Front turn signals.
Resistor plugs into one ground and the wire that controls the turn signal itself. Here's the resistor and the diagram:
6 OHM 50W 2 BULB LED LOAD EQUALIZER RESISTORS TURN SIGNAL BLINKER FIX WITH MOUNTING PLATES AND COVERS | 1 PAIR
Not for all cars. For 6th gen, they need the resistor. The thing is that the car sends too high of a current (for the incandescent filament) that it needs to be regulated or else the blinkers will blink really fast/hyper flash. Here's a video of what I am talking about:

Their 1157 turn signals do not have them.
Thanks guys.

It looks like the bulb you are replacing has two filaments (the 1157 diagram)
The plug to the turn signal bulb should have 4 wires. Two should be black. It is possible that there are only three wires with only one black wire.
You will need a volt meter to figure out which wire the the positive. Turn on the turn signal, but do not turn on the headlights. Check for pulsating voltage (12V to 0V) on each of the non-black wires on the electrical connector. That will be the + for the turn signal.
Double check by turning on the headlights with no turn signal. The other non-black wire should have constant voltage.
You should be able to look at the bulb to figure out what filament is the turn signal. The two contacts for the turn signal filament should touch the pulsating 12V wire and the proper black ground wire.

If there are four wires, are two of them ground? Would you happen to know where I can look for pictures of the socket online? I haven't gotten to the bulbs yet (those darn washers are giving me a hard time ATM).
Thanks for the help! I have electrical experience (not with automotives) but seeing that this is a car (and my only one) I dont want to mess things up.
So basically, leave the parking lights off. Turn on the signal. Connect the negative probe to the chassis and use the positive probe to test the two colored wires. Whichever wire gives me fluctuating voltage readings, that's the one I want. To double check, turn on parking lights and check if the other wire has a constant voltage?

The hazard lights use the turn signal lights, so you can use them.
Each bulb is really two bulbs in one, so each filament has a ground wire.
