How come my dash lights dont come on i cant smog my car if those lights dont li

There are many reasons that dash lights will not illuminate. It could be the fuse, switch or bulbs. I would recommend to diagnose the dash lights circuit to advise further. The reason that you cannot pass a smog inspection in CA due to no dash lights illuminating is because the state requires that we confirm the check engine light or MIL light properly illuminates to advise the driver there is an emissions related component that is not working properly.

I found a short in wiring on a couple of cars I worked on near the instrument cluster.
