I'm still looking for the parts number that I can use in my circuit.  Please give me an example what kind of photo diode I should use, thank you.

Hi guys, I tried to build a park-aid and I am looking for the parts for Infra-red Led and Photo Diode.  I used a KIE-7305-1P and KIE-7304-1P.  Unfortunately, it doesn't work.  Can you guys please give me the part number for those diodes, thank you?  :-[
