Does anyone know the headlight bulb designation for the U.S. Lancer?
You might find it in the back of your car manual.

To give you a better idea of what I mean, on my Mitsu GTO it uses H4 bulbs.

 

9007. No doubt.

My only question, and I can't find this, is the wattage.

 

55 watts is each bulb in our US lancer. Silvannia Silverstar makes some of the brightest replacement bulbs I have ever seen. Give them a try. Cost around $30 each but definately worth it. You can actually see at night with them....now if I could only get me some windshield wipers.....
