This mod allows the use of the lights that come with the W990 edited by Harven to work on other trucks such as the viper2, k100e and Rezbilt. *I take no credit for the lights only making them usable on other trucks. Requires Kenworth W990 edited by Harven to work. MUST BE PLACED ABOVE THE W990 TO WORK. ONLY WORKS WITH TRUCKS THAT HAVE LIGHT SLOTS. *added missing Rezbilt parts. *added all known working light packs to required mods. *added k-100 compatibility
