Ok i know everyone says the dome light bulb is DE3175 BUT! mine for what ever reason is different and i cant find any information on it someone help pleaseee i added a picture of the 3 bulbs it has..

 

Usually you should be able to find some markings on it to determine which bulb it is. I would imagine you can take it in to any auto parts store and match it up visually pretty easy.

 

crazy as it sounds i took it to autozone & pepboys and they had no bulb that matches it.. it has the prong of say a #194 bulb but bigger size bulb i think im gonna get a #194 bulb and try that cause i cant seem to find it..

 

Even though I would find this hard to be the case if worse comes to worse you could go to a junkyard and pull out the dome fixture on another lancer.

 

go to superbrightled.com . i purchased all my lights for the odometer, dash, and dome light from them. you wouldn't believe the difference that the white led makes in your car. way better than the ugly amber color. what you want in s festoon bulb. i believe it is the 3022 festoon bulb, if memory serves me correctly. they have different styles depending on what you want. i think i had to squeeze the prongs together just a little to get the bulb to fit snug, but works like a champ. if you're interested, let me know and i'll find out exactly what bulb you need. hope this helps.
