{{disambig}}
{{file|lights|rad}} is a [[RAD file]] which is always automatically read by the lighting compilers. 

* For an incomplete list of vanilla lights.rad files, see [[:Category:RAD#L|Category:RAD]]. 
* For documentation on how to create and use a lights.rad file, see [[RAD file]].

{{note|Default lights.rad files are normally included with {{src|4.1}} games, but not {{goldsrc|4.1}} games.<br>Some games, such as {{hl2dm|4.1}} and {{src13mp|4.1|nt=0}}, relied upon base {{hl2|4.1|addtext='s}} lights.rad, and no longer have a default lights.rad as of the [[SteamPipe]] update, as their new standalone {{path|hl2}} folder does not contain a lights.rad.}}
