Here is what i got...
2003 - 1500 hemi auto 2wd

When I push the brake pedal
1. LH brake lights seem ok
2. LH reverse light is about 1/2 lit
3. RH brake lights ok
4. RH reverse lights not lit at all

When the Left Hand blinker is on
1. LH blinker basically works
2. LH reverse lights flashes at about 1/2 brightness
3. RH blinker functions correct

When the Parking/Head Lights are turned on
1. LH tails are 1/2 brightness
2. LH reverse light is 1/2-1/4 bright
3. RH seems ok

Some things I've done/checked
1. Tested new LH tail light assembly from known good truck = NO CHANGE
2. Swapped out the silver box attached to under hood fuse tray (same part number) = NO CHANGE

Anyone got any suggestions or anything?

In the old days, you'd get weird stuff like that happening when the grounds got messed up (the lampholders connection to the body). But I think now they run a ground wire (2 wires) to all the bulbs right?

I guess I'd start at the lights and check the harness and all connections and figure out how they are grounding the harness.

Do you have separate fuses for trailer lights on the 03? If so it shouldn't be the trailer wiring (if you have any).

I've also heard of some problems with the wiring and connections under the fuse block.

Good Luck!
