Key On and Bulb Test are ≠
Bulb Test is just before Start and on spring for start the car. IOW you can't just let key on w/o turning to almost start.
If your car doesn't have temp light/gauge fix then gauge should peg and light nothing when you hit bulbtest/start. If have full fix then opposite should happen. Many just cut temp gauge wire and never bother w/ the light and do nothing for the Bulb Test.
CEL BAT and SB lights
are Not on Bulb Test line on ignition switch.
CEL is on when ECM is on and engine not running.
SB light is a function of blue dingy thingy and always on for 5-10 sec. See my Cave,
Chime UnitBAT is for the Alternator and on when engine not running.
If these light(s) won't turn on as said above then have other problems.
Can be a lot of things including bad bulbs, bulb sockets, etc, in the dash. see

Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
