Some cars have lights with a reflector, in the case, a point light correctly place, with a perfectly reflective material on the reflector could make it.
In other cases, you may also add two spotlights.

In any case, I suggest that you scale down the lights.

If it's the turn signal or taillights, points lights will suffice.
For the front light, and if you are using Superfly, you may use a blackbody node to control the  kind of light: the more kelvin, the more blueish the result.
