The car is a 1994 Acura Integra. The previous owner installed clear lens for the front turn signal/side marker assembly. I believe the stock ones are supposed to be yellow color lens. The bulbs listed for them are 1157 and 168. They currently have clear bulbs in them but I would like to put in amber color bulbs. I was able to find the amber version of 1157. But I don't see the amber version of 168. I did come across 194na and 2827 but not sure if I could use those. Also does anyone know what the difference between natural amber (NA) and amber (A)? Any suggestions welcome, thanks.
