did u have to splice or rewire anything for the switchback to work?

or did u just buy the bulbs and they magically switch back and worth?

 

rear coupe LED blinker is a nice look as it blinks on and off but is NOT as visable as the stock bulb(which is hard to see already especially with the brakes on) i tried this /:

 

Yes, you have to install a different type of socket and splice into the parking light. Check here for the DIY I made: https://www.myg37.com/forums/d-i-y-i...itchbacks.html

You could always buy the 20 LED High Output ones that they have. I just didn't feel like spending $80 on a pair of LED lights
