My taillights work during the day on my 1993 Chevrolet 1500 (350TBI) but as soon as I turn on the lights for nighttime driving my taillights + brakes lights don't work (but 4 ways and signal lights do) Also my front left (driverside) blinker works but doesn't glow.

All bulbs are good, I replaced them - I don't know what to be looking for?

Also my reverse lights don't come on.

Inspection is coming up soon and I need to find a solution, anyone?

 

As you described it sounds as if you may have day time running lights (DRL) I not sure 1993 production year had them. but. It sounds like you may have corrosion, bad connection, possiblely failing headlight switch.

 

No day time running lights on my truck, or at least there haven't been any since I bought it... I think. I don't normally look at the front of the truck while it's running. I can tell you no lights on front light up during day except for turn signals, obviously.

 

check the actual **** that you turn for the lights connections fuses ect. also check your wire connections and see if your getting voltage
