I can fit up to 7 inch diameter lights on my guard, it just came in today so Im real happy about that, pep boys has real good service on delivery lol. yea I usually just say fog lights but Im looking into high power driving lights, I was thinking about getting kc daylights or KC slim lites but they are real expensive. they want $200 for the slim lites. Im not very familiar with Hella but now I thinking about those seeing as Walnuts suggested them and I like the look his truck has. which is better though KC or Hella? I know KC has been around for a long time which is why I was looking more towards their lights at first.
