Winka 2 Taps 3157 Light Socket Harness Wire Connectors for Bulbs, Turn Signal Lights 4 pcs

I was retrofitting leds into housing made for incandescent bulbs and drove myself crazy trying to find dimensions for led plugs that would fit. Spoiler alert: nothing on any site that easily comes to mind has this info. For somebody else that might be doing a more involved project, the following info may be useful.I took a risk and bought these since they seemed like they might work. For the record, the hole required is slightly larger than 1”, with 3 slots around the circumference that I ended up dremeling in. The bulb holder is held into the housing by tension by the 3 prongs from a squishy rubber gasket. However, the spacing for my application was too large so I had to go to the local hardware store, buy some extra rubber washers, then cut them to size and stack them until it fit nice and tightly.Also, make sure to take a multimeter and test out the wire’s circuits. The black wire isn’t necessarily ground

For laymen, know the specifics of sockets is important to learn or be really sure of. but thats only part of it.T10, t15, t25 - all 3 are different sizes. In addition, there are the tangs, or nibs. These use specific patterns. So if you are replaceing a socket to upgrade to LED - you need to really examine the photo's carefully if possible to be sure your socket fits AND can be installed and locked into place! Different car manufacturers use different nib patterns making this difficult.

i actually ordered the wrong connectors. I need the white ones for the lights up front.

My F150 takes 3157 front turn signal bulbs. I thought this would be a direct replacement, but there are only 2 locking tabs, not 3 like on my truck.Overall quality is fine, wish they fit.

The sockets fit like I needed them to. However, I ordered 2 packs as I needed 6 of them. Out of the 8 I got, 3 of them did not work properly. The one filament lights up but not the second. All 3 were faulty in the same way.

New bulbs had a decent amount of play in some of the sockets so it wasn’t making good contact. Pain to deal with

As expected they needed slight modifications to fit. Worke fine

These worked perfect to update my old truck turn signal bulbs (1157) to the newer LED bulbs (3157).

Good but not for me
