I was curious if the T/A Bezel covers any dash lights on the gauge cluster? If so, what lights do they cover?

 

they don't cover any of the lights

>>My gauges in my Z<<

They just outline the dials real nicely

 

If you put them over your stock gauges, they just will cover the symbol indicating what each gauge is for on the bottom row (i.e. the fuel pump symbol for your fuel guage will be covered. If you buy a Firebird applique or overlay, the symbol will be in the right place, but it wont light up at night. No biggie, as I'm sure you know what eash of your gauges are for.
