tek light issues (ballast?)

[gregzz4]

Just to rule things out

If you have a multimeter, test the switch
If you don't, swap the switches around and see what happens

And the odds of 4 bulbs burning out at once are probably huge, but ...
I'd be inclined to, one at a time, try the bulbs that are out on the ballast that still works

Just to be 100% sure you need a new ballast
