i searched but all i saw was a single filament bulb. the reason i ask is that im about to install 06 projectors and want to have the blinking lights stay on.
do i have to change the base of the bulb to the 7443 one? or is there an easier way?

 

even if you change it it won't power up. it's the socket that has power to the second filament.

You will need to get the 7443 socket and wire it up

 

thanks ivory for the info. i'll problably swap out the 04 sockets to the 06's i'm sure the they don't sell the 7443 sockets at your local parts store.
