I am confused which lights are right for my car (1993 Q45)

[Infinitiguy19]

I went to the Sylvania's website to find the that the front side marker lights are a different number that are in the Q45 manual.

Which is right The Manual from the manufacture that puts out the car or the people who make the lights for the car?

The front side marker light is 194 in the Q45 manual and 168 in Sylvania's website.

Take the dead bulb in and compare. I thought 168 was a tailight on the FGY33. Could be a side marker light also, I guess.

They are exactly the same but couldn't they be different amps, volts and watts.
