SDL 2 + OpenGL 1.3 - No light - opengl

Question

I have this project for Win/Linux that has to use OpenGL 1.3 because later on will be ported to another platform that only supports that version.
I have a basic scene with a directional light and using GL_COLOR_MATERIAL but all the polys are rendered completely black and I cannot find what is causing them to render like that. This is the code I'm using to set up OGL and SDL:
static si GaGlSdlSetup()
{
if (SDL_Init(SDL_INIT_EVERYTHING) < 0) return 0;
GaPrPrintToConsole("\nSDL Properly initiated");
l_sdl_window = SDL_CreateWindow("Window Test",
SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED,
SCREEN_WIDTH, SCREEN_HEIGHT,
SDL_WINDOW_OPENGL
/*SDL_WINDOW_FULLSCREEN | SDL_WINDOW_OPENGL*/);
if (l_sdl_window == NULL)
return 0;
GaPrPrintToConsole("\nWindow created");
// Create an OpenGL context associated with the window.
SDL_GLContext glcontext = SDL_GL_CreateContext(l_sdl_window);
if (glcontext == NULL)
return 0;
GaPrPrintToConsole("\nContext created");
return 1;
}
static si GaGlSetup()
{
const float amb = 0.2f;
const float LightAmbient[4] = { amb, amb, amb, 1.0f };
const float LightDiffuse[4] = { 0.2f, 0.2f, 0.2f, 1.0f };
const float LightPosition[4] = { 1.0f, 2000.0f, 2.0f, 0.0f };
glClearColor(0.3, 0.3, 0.8, 0);
glClearDepth(1.0);
glViewport(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(45.0f, SCREEN_WIDTH / SCREEN_HEIGHT, 0.1f, 35000.0f);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glEnable(GL_TEXTURE_2D);
glEnable(GL_DEPTH_TEST);
glEnable(GL_POLYGON_OFFSET_FILL);
glLightfv(GL_LIGHT0, GL_AMBIENT, LightAmbient);
glLightfv(GL_LIGHT0, GL_DIFFUSE, LightDiffuse);
glLightfv(GL_LIGHT0, GL_POSITION, LightPosition);
glEnable(GL_LIGHT0);
glEnable(GL_LIGHTING);
glColorMaterial(GL_FRONT, GL_AMBIENT_AND_DIFFUSE);
glEnable(GL_COLOR_MATERIAL);
return 1;
}
And this is the basic rendering code. I have confirmed the values for the l_red, l_green and l_blue change according to each vertex and are within the range [0,1], and I'm currently rendering polys without any texture:
static si GaGlRender()
{
glClearColor(0.3, 0.3, 0.8, 0);
glClearDepth(1.0);
glBegin(GL_QUADS);
.
.
.
glColor3f(l_red, l_green, l_blue);
glVertex3f(l_mesh_vector_1->vx, l_mesh_vector_1->vy, l_mesh_vector_1->vz);
.
.
.
glColor3f(l_red, l_green, l_blue);
glVertex3f(l_mesh_vector_2->vx, l_mesh_vector_2->vy, l_mesh_vector_2->vz);
.
.
.
glColor3f(l_red, l_green, l_blue);
glVertex3f(l_mesh_vector_3->vx, l_mesh_vector_3->vy, l_mesh_vector_3->vz);
.
.
.
glColor3f(l_red, l_green, l_blue);
glVertex3f(l_mesh_vector_4->vx, l_mesh_vector_4->vy, l_mesh_vector_4->vz);
glEnd();
.
.
.
SDL_GL_SwapWindow(window);
}
Any idea what could be the problem?
EDIT1:
I added the directional light because I could not get any vertex color to be displayed by using only GL_COLOR_MATERIAL, disabling the lights and leaving only GL_COLOR_MATERIAL displays the same result
EDIT2:
Found the culprit: glDisable(GL_TEXTURE_2D) I thought you could leave it on and it would affect only textured polys, but apparently not...
