Turn signals colors in CaliforniaM?

Do turn signals on a car have to be yellow? I saw someone have white once but im not sure. I live in los angeles. Any ome know?

Other answer:

Front turn signals back in the early 60s and earlier were white (and all rear turn signals of that era were red.) Amber (yellow) were found to be more easily seen and thus were required in later cars and trucks. Amber can also be used as a rear turn signal, but not for any other light on the back. IE: brake lights and regular tail lamps must be red.
If the lens is broken so there is nothing in front of the bulb, that's not ok.

White on the rear is not allowed. The rear turn signals must be yellow/amber or red.

The law still allows vehicles to be driven with white turn signals on the front (if it's white because the lens is white, not if it's white because the lens is missing or broken) because there are still some very old vehicles from when cars were made with white front turn signals.

You can believe idiots that don't know, or you are read the LAW: http://leginfo.legislature.ca.gov/faces/…

Vehicle Code, Equipment, Signal Lights http://leginfo.legislature.ca.gov/faces/…

and I quote:
" 24953. (a) Any turn signal system used to give a signal of intention to turn right or left shall project a flashing white or amber light visible to the front and a flashing red or amber light visible to the rear."

See! The LAW says you can have white turn signals. No year limitations.

Prior to 1968 white turn signals on the front were legal. Since 1968 turn signals on the front must be amber and rear turn signals may be either amber or red.
White lights are only legal at the "front" of the vehicle. That's why reversing lights are white.
Turn signals to the rear have to be red or amber, to the front amber only.
A thought shared.

White or yellow in the front; yellow or red in the back. All states.
