Bulb is 7440 it is the wedge type bulb. I guess you pull it
Straight out of the socket. 2003 Toyota echo. It is very difficult
To remove. I do not want to break it. I already replace the front
Turn signal 1157 which turn out. That was easy.

The 1157 is dual filiment, maybe park and turn? 1156 is single element,
Try grabbing at the base and rock slightly side to side as your are pulling. Leather glove can't hurt.
Good Luck

Thank You so Much
