Hi Willi,
I wouldn't use your bright LED at 50mA for this turn signal. Its absolute maximum continuous current rating is 20mA.
You must be careful when you see the word "peak". It usually applies for a multiplexed display, where each LED is lighted only for a moment and the multiplexer scans thru the rest of the LEDS before briefly lighting this one again. Therefore each LED is off most of the time and appears dimmer, so needs a higher peak current to appear normal.
Many LEDs have a peak current rating of 1A for multiplexing use. Their datasheet usually shows a derating graph showing allowable current vs time. This LED doesn't show that graph.
