Yes, the ignition on a trailblazer can cause head lights to work improperly.
One thing that could cause this would be a faulty ignition switch, specially if you do not have ignition (cluster) lights. Just a thought...
most likely is a faulty chime switch,or a faulty ignition switch
Passlock sensor (Ignition housing) Or body control module fault
Could be either a bad ignition switch or a bad voltage regulator (not opening circuit on shut-down)
sometimes the head lights and tail lights may be fused separately,check your fuses.you could have a bad ground.thats just two places to start.
Headlight power is not controlled by the ignition switch or keys. Damage to the turn signal lever could cause the 'flash to pass' circuit to stay on. Damage to the light switch could also cause the lights to stay on.
It could be a combination of two simple problems. First, check that your parking light switch on the top of your steering column is OFF, as this will keep the lights on even if the ignition switch is off. I believe this switch is necessary because your lights turn off automatically when you turn of the engine (ignition switch) Aslo, you must check your (combination tail light and brake light) rear bulbs as this could cause the break and tail lights to remain on when the car is started (ignition is on). GOOD LUCK !
Ignition is required for an engine to work. Failure of ignition would prevent the engine working.
If your side lights stay on when your ignition is off on a Granada Scorpio Costworth, it could indicate a wiring malfunction. You should also check the fuses.
Broken switch, replace it.
a short can indeed cause this. Any grounding of the positive flow can cause numerous problems. Fix it befor you have a meltdown or fire.
coil plug would cause the problem sometimes or could be other things
Its the ignition switch change it and that will stop the problem
If a 1987 Chevy Suburban has lights and horn, but no ignition, gauges, radio, or interior lights it could be a ground wire problem. It is possible that there is a short somewhere. Also check the dome light for a possible water leak in the headliner.
turn the ignition off
This sounds like a starter problem with commutator or brush problems. joedi
i dont know maybe your lightbulb is messed up. There could be many possibilities depending on the situation. If a high wattage unit comes on (like an air conditioner), there could be a drain on the system that causes a light to dim. Sometimes during a storm, there could be a problem at the power substation including a power surge or break in the system, that could cause lights dimming. If too many strands of lights in a series are connected, you run the risk of overloading that circuit, which could cause dimmed and blown lights, and potentially dangerous situations. Consult a Master Electrician for more information.
No spark would usually be the ignition coil.
A faulty pump could be the cause of this problem. or a loose connection due to vibration.
Blown fuse or defective brake light switch.

Yes, it could.
