I thought I’d take a few pics while installing my new low beams (H1 bulbs).

let me start by saying disconnect the negative terminal on the battery.

the low beams are on the side of the headlight assembly closest to the side of the car. they are located behind a black plastic cover that is labeled with arrows and says top and open and close. twist it and set the cover to the side. make sure that the gasket is in place.

the third pic is what you'll see with the cover removed - the back of the bulb with a wire still attached. before unhooking the clip, i found it easier to disconnect the wire. just pull on it and it will come loose. it does not take much pressure at all.

the hardest part for me was figuring out the clip. couldn't see how it worked since the space was so tight. finally got a mirror and was able to see how to get the clip out (see the first picture). you'll notice at the bottom of the pic is a wire that has been bent like a square. push in on it (it takes a fair amount of pressure) and move it to the left. you'll feel a click and the clip should be released. the clip is on a hinge, so lift up from the bottom of the clip and rotate it up.

the second pic is the coolant container thing that needs to be unbolted if you want more room to access the passenger headlight. really easy; just 3 bolts (10 mm) and lift it out of the way. the hoses are very flexible so it's easy to put it aside. you will find some wires that impede moving things easily (the round cover for example can easily get caught up on these wires) but with some patience and effort to move the wires the little that they allow will get you the space you'll need. on the driver side, i found taking the cover off of the fuse box and taking off the cover of the air filter helped give me a bit more space.

once the clip is undone and you've lifted the clip up, the bulb will pull straight out (horizontally) toward the back of the car. you'll notice in the first picture that the bulb has a plate on it that is circular in shape except for one side that has flat edge to it. remember where that flat edge is; your replacement bulb will need to go in the same way.

really, changing these bulbs is pretty easy. it's just that you don't have a lot of space to get your hands into, but once you see what you have to do, it's not hard.
