For some reason my els is not fully functional. All the functions work just fine including the siren and the stages but only the tail lights are working. The lightbar and other lights are not. They were working previously a day prior, and when i went to launch gta v with lspdfr it just randomly stopped working. This has happened in the past and im not sure what I did to resolve it. In the day prior and to the new day, I had not installed or uninstalled any plugins or anything into the game itself using openiv or drag and dropping. My logs shows that els was loaded and that I have no errors. Regardless Here are the logs for ragepluginhook, els, advancedhookv, scriptshookv, asi loader, openiv and scripthookv.net. And as a side note none of my els vehicles are currently working tho they were working the day prior to these logs. 

AdvancedHookV.log asiloader.log ELS.log OpenIV.log RagePluginHook.log ScriptHookV.log ScriptHookVDotNet.log

Same issue with me. Can't find a reason anywhere. Happened about same time as you.
