There should be a high beam at the bottom of the speedo and oil and charge lights on the middle one.
If they aren't there then there are probably places to put globes at the back of the guages and the printed circuit probably has them wires up already.
All the clubby dashes are pretty similar just the tacho sort of got put on the right hand side the front facia type bit may not have the cutouts so tha you can see the warning lights so you might have to try and source this bit from a standard clubby one.
Hope this helps I still can't imagine why it would have no warning lights though
One guess might be that they were taken out when the three guages in the middle were added (I am guessing one of these is Amps or volts and another is oil pressure) so the original sensors were probably taken out to fit the sensors for these.
Hope this helps
