Fuse is good and tests with 12 volts. Reseated fuse. Light bulbs are good and reseated as well. My right side rear lens had standing water about halfway inside the clear lens part. I did drain the water. What is keeping my left and right reverse lights from turning on?
Thanks! There was standing water half way indide the clear lens part.

Check for stored DTC using Forscan. The circuit may have been disabled until the codes are cleared. Was the water up enough to make contact with the lightbulb socket pins?

Not quite, but I figured the water did splash up to the contact when riding on bumpy roads. I don't know how long the water was in it. It's dry now since I drained it today. The drivers side rear lens never had water in it. I discovered the in-op reverse lights yesterday when I checked all my lights when I thought I was going to get the truck inspected. I did disconnect the battery for 2 mins hoping for a change but no change.

The Reverse lights are controlled by the BCM and are protected from over-current by a FET (Field Effect Transistor) circuit. If the FET sees an over-current, it shuts the circuit off and then resets automatically on the next ignition cycle (Off-On). If the FET trips too many times, the BCM sets a DTC and the FET remains off until the problem is fixed and the DTC cleared.
Chances are your BCM has set the DTC. You need FORScan or a diagnostic scan tool which can communicate with the BCM and clear the code(s). A typical OBDII reader will not work for this.
You can try disconnecting the battery, but if this is even going to work, you need to leave it disconnected for at least 30 min.
I'll try the battery disconnect for 30 mins.
Thanks!
Get yourself a jumper with alligator clips on both ends so when you lift the NEGATIVE lead on the battery. You can jumper between the NEGATIVE and positive leads. A short interval while jumpered will insure a discharge of any stored energy in the electrical system.
What do you mean by "you can jumper between the negative and positive leads?"
Are you saying, disconnect the negative cable from the battery and then connect the jumper from the positive post on the battery to the disconnected negative cable?

No left or right reverse lights
