I tried searching on the forum but didn't see an answer...I have an 03 coupe and I want to swap the bulbs from a 7443 to a single filament 7440 so you can't see them all the time in the headlights. For the 03's do I need an orange bulb or a regular white bulb? I know the 06 ones need an orange, but I'm not 100% about 03-05.

 

the 03-05 head lights had an amber lens so it was a clear bulb for dual filament.. the 06 are amber bulbs

 

I thought that might be it. Thanks for the help!

^ that way does work. 7440 -7443 bulb's are not interchangable.
