What size are they, and are they hard to install. Thanks for the help.

 

194's. Installation is quite easy. Just twist and pull the light socket...just remember the position of the light socket as it has to be put back in at the same position.
If you want, you can also take the headlight bolt off and pull the headlight out for easier install. You really have to tug at the headlight after the bolt is removed as it is also held in with a plastic ball and socket type of fitting. Good luck.

 

You could also use a 168 bulb in there.

 

I used the 194 polarg M4s. They look good with the HIDS.
