I hate to tell you this, but if you get a cop on a bad day, then you're going to get your jeep impounded. The HID lights did not come as stock, are not designed to be in those housings, and thus....are not DOT or Transport Canada certified. I know that I may get flak for saying this, but there is a reason for this. You mentioned that your lights lit up the back seat of a corolla....imagine just how blinded the driver was of that car. (I am aware that there are alot of things done to vehicles that make them technically illegal).
Don't get me wrong, if you're going to the trouble of putting in HID's, then get the proper lenses for them as well. If the lenses don't exist for a particular vehicle, then don't bother. All an HID conversion in a normal reflector is going to do is squirt off everyone else on the road. When you had your Lincoln....those housings were designed to have the HID bulbs in them, your jeep doesn't. The way the lenses/reflectors are designed is to keep the light on the road, and not up in the faces of on-coming drivers.
If anyone from National, Modern, or any other place that sells parts reads this, I hope they get the hint and stop selling these kind of products. Anything is legal to sell, if you look at the box, it will say "for off-road or show use only". This means it's not meant to be used on the road. However they will never say this when they sell them, cause then they wouldn't make money from the sale. I mean no offense, this is the nature of the business, but I wish that morals would dictate things once in a while.
I don't mean to sound harsh, but it's a bit of a peeve for me. I like being able to see where I'm going. Please don't take what I've said here as giving anyone trouble, just venting a bit.
