When I had my DRLs still hooked up I just drove with all the fogs and headlights and yet people still did not see the truck coming and it has not gotten any worse since I disconnected the DRLs and now I am running with no lights on in the daytime.While you at it you should also disable the airbag, and ABS systems.
Since DRLs first came out on cars I have seen more IDIOTS drive with just DRLs on at night so that is a real good safety feature. :tu:
