Is there a difference between #73 & #74 bulbs (for HVAC)?
 

I was on Advance's website, getting prices for those little bulbs that light up the HVAC panels & also near the door locks... For my car (97 TA), they suggested bulb no. 73. But I've heard people say #74 is the correct bulb.
I went to Advance, and both 73 & 74 look the same with the exception of one having a blue "thingy" inside and the other is peach-colored.
The bulb that I popped out of my car was blue, like the 74's, so I guess I should go with that.... but just want to be sure before I open the package & destroy any chance of returning these. :)

If anyone knows the difference, I'd appreciate the feedback.
Thanks!
