its was taken from nemesis's site:
I will try to help:

1. In 2D view, right click equipment-searchlightbase

2. "n", enter:
K: targetname V: spotlight
K: #set V: 1
K: #group V: 1

3. 2D view, right click info-splinepaths. this is where the light will search for you. place several in a loop to create the search effect.

4. "n", enter for first splinepath:
K: targetname V: spotpath1_1
K: target V: path1

5. Next spline path:
K: targetname V: path1
K: target V: path2

6. keep doing this until you reach the last splinepath and use "spoypath1_1" for it's target.

7. For the script, place "exec global/spotlight.scr"

8. That should work work; I hope
