How can replace the tiny turning signal bulb in the corner ? Do I have to loosen the whole headlight ? What screws do I have to take out to change it ?

 

I believe you have to fish your hand through the wheel well lining. Just remove a few plastic push pins and you can get to it.

 

To loosen and remove the headlight assembly....the bumper will need to come off first, allowing access to the mounting bolts and bulb wiring connectors for the assembly. The size is 24/2.2 CP.

 

Yes just saw it in the owners manual today

You don't need to remove the headlights or the bumper. Pop a few of the clips off and reach through the liner

 

its a 1/4 turn twist iirc
do both sides as the other will not match color or brightness
and it will burn out soon too

At our cars age its wise to replace all the turn and brake bulbs= 20 bucks well spent
and the hid kit to replace its issues or a low beam bulb goes
59$ www.hidextra.com suggest 5000k color low beams
