Actually you don't need any mods to make lights look good. Simply locate your visualsettings.dat file using openIV and with edit mode on, right click, select edit, and press ctrl+f, search for car.default and you will see emisive day on and emisive night on simply edit the values to whatever fits you. Personally I have mine set at day 2000.00 and night 1500.00 but it's up to you. Also play around with other brightness options if you want but it's not recommended. Also for this to work postfx and shader quality need to be set to high or above. Happy modding
