How do you change headlight bulb on 03 Eclipse

First, make sure that the headlights and engine are off. Hot engine and hot bulb make changing it challenging. Reach behind the headlamp assembly and remove the electrical connector by pulling it straight out, towards that back of the car. Next, remove the large rubber seal that is on the back of the headlight assembly by pulling it off like the electrical connector. The electrical connector was in the center of the seal. There is a metal bar spring that goes across the back of the bulb assembly. It opens like a safety pin. Gently push down on the end of the metal spring. Once it is pushed down it will be out of its clasp and it will open automatically due to spring tension. The bar spring can be opened completely and then the bulb will come straight out the back of the headlamp assembly. To replace the bulb, first, make sure you don't touch the glass on the bulb since it may cause a hot spot and reduce the life of the bulb. There are 3 metal tabs that are on the bulb for the electrical connector. Position the bulb so that the "missing tab" is on the bottom. Put the bulb into position by aligning the 3 metal fingers on the outside of the bulb assembly into the openings on the back of the headlamp. They should seat fully. Once the bulb is in place you can close the bar spring by gently pushing down on the open end of the spring so that it engages the clasp. The spring will hold the bulb in place and you can verify seating by gently trying to move the bulb or by gently pushing and pulling the bulb. If it is seated then you can put the large rubber seal back on the back of the headlamp. Lastly you can pusht the electrical connector back onto the 3 prongs of the bulb. Don't push too hard and you might want to consider using some bulb grease to make it go on easier and to protect from corrosion. I changed both headlamps in about 3 - 5 minutes.

The headlight "clips" on this model can prove to be a nightmare, especially on the drivers side where room is at a minimum. The clip is held in place by a screw on the fender side (driver side) and is nearly impossible to get back in place, so just remember to seat the bulb in place from the back of the bulb first - with the missing tab at the bottom! It shouldn't twist around or turn, THEN PUT THE SWING THE CLIP THAT PIVITS FROM THE SCREW, BACK ONTO THE BACK OF THE BULB SECURING IT INTO PLACE. Next, place the large rubber boot labeled TOP TOWARDS THE FRONT of the car and let it form a water tight cup around the light fixture. Lastly, replug the wire harness back into position! You are done! Just check the lights while the car is running, high and low beams! ~Greg
