I want to replace the housings of my headlights. Not sure on some things.

For example: http://www.carpartswholesale.com/v5/...Listing+Page:1

This product looks like it has 3 bulbs. I'm pretty sure my 01 coupe only has 2. 1 (9003) headlight and 1 amber. I wouldn't be able to use that other bulb would I? Would it interfere with anything?
