I just installed my Opt7 LED headlamps and fogs. I like them, except I have a little issue that I need to fix this afternoon. I think I know what the issue is. Anyways, I've had HID before. Now, I could be wrong, but I had them in my old '09 Corolla and I hated them. I didn't like that they had to "warm up" to get to the full brightness level. It could have been that I purchased a low-end HID kit, but I really didn't like them. The brightness of the LED's and the fact that they don't have to "warm up" is great for me. I personally would recommend LED and specifically the Opt7 brand. Seems to be what a lot of guys on here recommended and I'm glad I went that direction.
Here's a link to my album with the install:
