Code:

glBegin(GL_LINES);

glVertex3f(vertex_x, vertex_y, vertex_z);

glVertex3f(vertex_x + normal_x, vertex_y + normal_y, vertex_z + normal_z);

glEnd();

Note that depending on your coordinate system, you may want to multiply the normal values by a constant so they aren't way too big, or way too small.
