No, switchbacks are light bulbs that start one color, then turn another color and then back again. I have some LED switchbacks in my front turn signals that stay white until the signal is turned on, then they flash yellow and back to white. So when the signal is on, they alternate yellow to white and when the signal is off they "switch back" to white.
What Red Rocket said lol

Good info Red. A concise explanation of what a switchback is all in one sentence. :thumbsup:

Edit: mine are white until the signal is activated, then flash yellow, then switch back to white when the signal is off. Be aware if you use them: I installed them and found out the next morning that the only brake light that worked was the high mounted center one. I ended up needing load resistors in the FRONT marker light circuits. Weird. Anyway now I have all white lights in front which amounts to 5 on each side plus 3 more small individual LED's. (Yes I have full-time DRL's and fogs) Until the signal is on anyway. Probably illegal as hell LOL. The first pic is with lights on, no signal. The next two are signal switchback bulb flashing yellow. Sorry, haven't figured out how to upload videos from my phone.

Oh yeah I forgot... the 4 high mod too so the low beam HID's stay on when the high beam HIR's turn on. HIR's can't be color matched unfortunately. Now THERE's some lighting!

Ahhhhh... now I understand what you guys mean by the term "switchbacks".
My question is, how do you wire them up? Piggyback/tap into the turn signal wiring, using resistors?

Add your resistors and replace bulb. & on mine i did both of my resistors on the front and both still hyper flashed so what i had to do is open the t-connector back up and squeeze the metal piece real good and checked them again, worked fine ever since @Tonyrodz

Keep in mind there is a type 1 or A and a type 2 or B style switchbacks

There's a type B or 2. Thats what I have in mine.
Then there's a type A or 1. That is what red rocket has.

It depends in your preference, both are legal. Type A is more like factory like the new style trucks. Type B gives a bit more custom look and more noticeable imo, because it flashes with white and amber instead of only amber and the white is so bright it gets the attention of other drivers.

I went with just yellow flashing because there's another white LED that flashes white in my housings so it alternates between the two, one flashing white and the other yellow.
