Keep in mind that aftermarket equipment laws are different from state to state and that aftermarket add-ons are not governed by the federal government unless they effect emissions.
In Ohio, add-on HID fogs are LEGAL, as long as you don't run them when there is no fog(not that you'll ever get a ticket), aftermarket HID headlights are also LEGAL, IF they are DOT-approved. Now, that said, no aftermarketer has ever(to my knowledge) attempted to meet DOT guidelines for headlights in Ohio, so it is a non-issue, but there is no law that would prevent them from doing so.

are clear corners legal? I don't have any as of right now but possibly might do somthing with the explorer in the future

exactly what you just said, "IF they are DOT-approved" BUT they are NOT. Look at ANY HID kit sold legally, there will be a line in there that will say 1 of 2 things: "for show use only" OR "for off-road use only"

silverstars are a replacement bulb that meets DOT specs.

HID kits like yours do not...

"these blue bulbs people use so much these days" have you looked at your own HL ??

If it'* got "DOT approved" you should be fine, if you get pulled over and the statement is proven to be false you can be required to remove them, but should not get a ticket, I would think.

No, we don't know what kind of kit you have unless you post it. What you sya about them is good enough for me.

Notice that I said only HID HEADLIGHTS had to be DOT approved in Ohio. Fogs don't have that stipulation, although they do in other states, thus the "DOT-approved" on the box.
