Turn Signals....
Locate the threaded stub (about 5 inches long) with the rubber cap on top next to the headlight.
Loosen the locknut and remove (unscrew) the stud.
This should provide enough clearance to reach
down and twist the bulb housing to remove.
Replace the bulb.
I just bought a replacement bulb from AutoZone.
If you have arms like Arnold you may need to go the other route by removing the plastic panel underneath the car behind the front end. Not as easy as the first method, but still doable.

The other options are:
Go in through the brake ducts - not easy with a Z06 or if you have screens
Go in through the bottom by taking out the bottom panel
The one that works for me is:
Turn on the headlights and back off one position to kill the lights.
Unscrew the 3 small screws on the black plastic housing around the headlight. Gently pull the housing clear. Reach down around the headlight unit and release the bulb holder. It unscrews counter clockwise but it has a plastic clip which you need to squeeze to release it. Change the bulb. Reseat the bulb holder and turn until it clicks back in place. Put the plastic housing back in place making sure to locate the small plastic tab in the bracket on the headlamp cover. Replace the 3 screws and close the lights.
10 minute job.
The bulb is a 4157NA





with DeeGee. Good advice there.
