These burn out. Not having the talent of a PaulJ to make my own, I found some on the Internet and bought them. The PC194 bulbs with the socket base sold for $0.69 each with shipping of $6.40. Considering my old Saturn had the 168 bulbs in the base and I paid nearly $8.00 each at the dealer I was quite pleased.
The place was BulbTown.com.
