Installing HID lights for this 06+ Lotus Exige was fairly easy, as everything was very accessible from inside the fender well. It only took a few bolts to have complete access to the headlight housing and ultimately the bulbs. You will want to get it up on a lift so you aren’t crawling around on the floor. This is a small call, which means clearance is tight, no matter where you are in the car.
Also, there is some minor drilling required, but no cutting or body panel adjustments required.
The Lotus Exige Factory headlight bulb (low beam) is H7
Here are some pictures from the install:
