Instrument Cluster Light Issue - Speedometer & Signal

Sounds like you have a couple of separate problems

For the front signal lamp, access the TS switch connector there coming out of the column and see if you have power at that connector for the right turn. If not, it's likely the TS switch itself

I assume from your description that the rear ones work? Both sides?

Speedo lights.........more than one? Check over the PC board in the cluster. If some lights do and some dont it's got to be "right there" Could be bulb(s), socket(s) or dirty connections on the PC board.

If your car "is one of those" with a two piece PC board, could be the transfer wire between the two.
