Hey guys! I'm looking for a switchback white/amber 4157 LED for the turn signals but instead of the amber flashing when the turn signal is on (amber>off>amber>off>etc.), it switches between amber and white (amber>white>amber>white>etc.). They used to call it switchback type A and switchback type B. Does anyone have or know where to get these?

Found it here but you can't order it... You gotta be able to get them from somewhere right?

So I found these but the bulb is 7443... I did a ton of research to see if 3157 and 7443 are interchangeable before asking here but all I found were people comparing 3157 with 3156 and 7443 with 7440.

I did some more digging and found this helpful diagram. Going by these two pics below, 3157 has the same setup as 7443 so it should work right? Anyone have any experience with this or can give me a straight answer please?





Edit: didn't mean to double post, sorry about that.

These are type 1.

What does type 1 mean though? It doesn't say anywhere.

On their other listings, they state type 1 as amber-white-amber-white. Another member also bought this exact bulb, I'll try to dig up that thread later.

3157 and 4157 are the same socket, they just differ in bulb construction and thus longevity, with the 4157 being the longer life one. 3157 is the socket that our cars use.

He says they are white-amber-white-amber in post 24.

Be careful with the height of some bulbs....bought a few that were too tall.

So did I, the C5 lens assembly has limited space in height of the bulb.
