Have any 3157 switch all white rear turn signal/brake bulbs?

Thats white when running lights are on, and brighter white when the brakes/turn signal are on?

I want to replace my rear tail light bulbs with LEDs, and my housings are all red.

White LEDs inside a red enclosure may not give the best performance. Usually you want the same color LEDs as your housing.

DPF/SCR technology summarized in three words: It doesn't work.

Usually you want the same color led for the lense it will be behind. If its clear then white will work. But if it is amber or red you want the same color bulb.

We have Red LED replacements for your tail lights that will be considerably brighter than stock.

As a rule of thumb, you'll always want to match the color of the lens with the color of the bulb you install. A white bulb in a red lens, will make the housing appear pink

Are they switchback or flashing?

I'm not sure what you are asking

"switchback" is a specific type of turn signal LED that stays white for the running light portion of the bulb and flashes amber when the turn signal is activated

We also have single color replacement LEDs for the turn signals that will function the same as your factory bulb, only considerably brighter with the instant on/off look of LED.

If you would like to learn about lighting technology, I encourage you to visit our research page here: Research

Thanks,
