Photographing light trails

Good day to you all,

Last night i stayed up until 4am to witness the current geminid meteor shower, i did get to see one very large shooting star but didn't manage to photograph anything out of the ordinary.

I ended up trying to capture some light trails from a T-intersection down the street.

How?

A sturdy tripod one must use
Switch your camera to full manual
Retract your aperture
3-30 second Shutter
ISO Auto exposure
Choose an angle that ensures cars headlights don't point directly down your lens
Shoot away!

Hope this little bit of information helps

Thanks
