For Bulbs, the whole bulb is colored amber or clear.
For LEDs, google '1157 amber white LED' and you will find many options. How you tell if the LEDs are any good is another question.
I bought some moderately expensive and very well reviewed LED 1157 but they were noticeably dimmer than $1 old school 1157 bulbs. I'm running bulbs for now, may never change.
I like the look of amber park lights, looks kinda mean.
