After installing these bad boys I am super happy with them. Extremely easy to install, so easy in fact I didn't even need the instructions. Two little tabs and some minor wiring, and yes, in the description it does state that you have to do some wiring... weird. However, it just replaces the marker lights, super easy, positive go to positive, negative goes to negative, slap some electrical tape on there you're good to go. Adjusting the beam pattern is also wicked easy, two silver bolts in the back of each housing adjust your projectors.Now these do only come with halogen bulbs, my recommendation is that you now have projectors, get some H1 bulb HID's to complete the setup and really utilize the full potential.The only issue I have is that some of the connections take a little fineness to install...
