Animating few textures and light

Hi mates.

I’m creating few videos about how to drive car (it’s for driving school).

How I can set up few lights and textures to animate in this way, that in NLA editor I will have an ACTION BAR which will be a controler of when blinker (turn signal) whill start flashing and when it stops.

Blinker (turn signal) - it will be an animated *.gif texture on light model, and there will be point light next to the light model to give some light expresions on the car (I use blender internal).
