Sounds like bad connection on the left side front clearance light. Look for loose connection on positive or negative wires. Look for corrosion at connections or wires and clean it up with wire brush. Look for exposed or frayed wires making contact to the trailer or wires. And if you haven't, try a different bulb. Could also be that run of wire is corroded beyond use. Try bypassing that wire with a temporary wire.

Good luck,

Since you do not have full (12VDC) at either light, then there is a resistance issue somewhere in the circuit. The problem is locating it with these runs typically buried inside the wall structures of the RV.

I would start checking where I could access (plug, pigtail end, and light bulb socket) to clean and protect the connections. A joint might look good, but still have some resistive issue from corrosion or dirt. And be sure to check/clean the ground connections too at any point...this could be the result of a combination of connections with slight resistance.

Best luck

use an OHM meter and check resistance between left light and trailer plug, both power and ground to see where the resistance is, might be a lot on both sides, then do the same to right side. Should give you a starting point.
good luck
