I'm working on a little projec and I wanted to to have to ability to change all of the lights in a level to a certain color..there is nothing for this that I could find, so I made my own:
[code:1:c8cdfc432c]
//=============================================================================
// LightTrigger.
//=============================================================================
class LightTrigger expands Trigger;
var&#40;&#41; float ColorB;
var&#40;&#41; float ColorH;
var&#40;&#41; float ColorS;

var   String DefaultBrightness;

function PostBeginPlay&#40;&#41;
&#123;
	Super.PostBeginPlay&#40;&#41;;
&#125;

function Touch&#40;actor Other&#41;
&#123;
			//Other.Instigator.BroadcastMessage&#40; &quot;fer shitzngigglez&quot; &#41;;
&#125;
function TakeDamage&#40; int Damage, Pawn instigatedBy, Vector hitlocation, Vector momentum, name damageType &#41;
&#123;
		local Actor A;
		ForEach AllActors&#40; class'Actor', A &#41;
		&#123;
			if &#40; Left&#40; A.Name, 5 &#41; == &quot;Light&quot; &#41;
			&#123;
				if &#40; Left&#40; A.Name, 11 &#41; != &quot;LightTrigger&quot; &#41;
				&#123;
				//instigatedBy.ClientMessage&#40;&quot;Light found!&quot;&#41;;
				A.LightBrightness = ColorB;
				A.LightHue = ColorH;
				A.LightSaturation = ColorS;
				&#125;
			&#125;
		&#125;
		
		Super.TakeDamage&#40;Damage, instigatedBy, HitLocation, Momentum, DamageType&#41;;
&#125;

This is simply a trigger like any other..in this state it can only be shot (no player bump) but programming for both wouldn't be difficult...After you add the actor to your level go into its properties under LightTrigger, there are 3 values: ColorB, ColorH, and ColorS, for ther Bright, Hue, and Saturation respectively. Instead of RGB, UT uses these values for lighting color..a few examples can be found [url=http://wiki.beyondunreal.com/Legacy:Colors]here[/url]. Pretty nifty...it would be nice to add functionality to record every light's object name and it's light color settings so they can be set back to default...pretty useless but cool
