Lights coming from light bulbs

How do I make the light fixture look like it is working (lit up)
because I put a light spot under it and I see light but it doesnt look
like the light fixture light bulb is working.

I think your best/only option is just to find a different model...

Most light fixture models have an on and off version

so the light shouldnt be a prop_static or and prop_what?

A quite good way of doing proper lights needs a few more entities. Here's a small setup i use:

1. prop_static : You choose a proper model to fit you map. For a lightbulb you find some fitting models in interiors.

2. light : Put a normal light entity directly in the lightbulb model. I
usually use a light and light_spot entity so my light isn't very
bright. You could choose for example a brightness like "255 251
204 20"

3. light_spot : The light spot entity is a lot better than a simple
light as you can change a lot more properties. Here are some properties
of my example:

Brightness: "255 251 204 50"

Linear: "20"

Quadratic: "30"

Inner Angle: "30"

Outer Angle: "60"

Focus: "1"

Pitch: "-90"

4. point_spotlight : To give the light that cool beam.

Pitch Yaw Roll : "90 0 0"

Spotlight Length: "60"

Spotlight Width: "60"

Color: "255 251 204"

Flags: No Dynamic Light

5. env_sprite : Last but not least a little sprite entity to give the bulb the last glowing touch.

Render Mode: "World Space Glow"

FX Amount: "150"

Sprite Name: "materials/sprites/glow06.vmt" (or one of the other glows, they are all quite nice)

Of course you can tweak each of these settings to fit your map, these
properties just serve as an example. If you use the sprite and
point_spotlight you won't really see if the lightbulb model is on or
off, as they make it look very bright.

This is the result of my example:

Thanks alot u should post a little tutorail it would be nice.

dude...nice small tut lol...even looks like a cool lvl u doing...

Also don't forget to set the skin on the model your using. You'll find almost all light models have a skin 0 and 1, 0 tends to be Off and 1 On.
