Some cheapo's from Autozone. no one else had 4" fogs, much less 4" fogs in a clear like my heads. So i grabbed these. I'll probably end up with clear ones before too long. But the box said "HID simulated" but it didnt matter to me. As i thought i need them asap. Havent hooked them up yet, so i still gotta see how they look lit up. May end up with some blue "HID simulated" bulbs in my heads to match
