They are bright. The taillights didn't impress me like I had hoped for but for $100 I'll let it go. The fogs work great. I actually used them by themselves on a 150 mile drive in the dead of night behind a buddy who was towing a heavy trailer and it tilted him down so my HID's were blinding him. I mainly use them for neighborhoods. I get out of work at midnight so I don't like HID's in people's windows as I'm comin down hills
