I bought some PIAA Mirror Orange 7440 for my rear turn signal on my '01 RX, and every CL post seems to have 7440 for the rear turn signal as well as piaa.com, sylvania.com and all the application searches say 7440. When I went to remove my rear turn signal bulb it looked like the 1156 bulb size, round and looks like a lamp bulb in my house. I tried removing it and it wouldn't buldge so now I'm wondering if I bought the wrong bulb? Has anyone had this problem? Thanks
