OK my opinion, nothing more…
I am not trying to be an @ss but two things.
1) Where are your relays, one for each two lights; I would not want to run full powered wires into my cab.
Yes nice to have both lines fused and it is needed but it needs to go to pin 30 on a relay then out to the lights.
The switches can be low powered fused switches/lines because a relay needs minimal amperage to activate.
Please add two relays to your circuit.
2 Aiming of the lights, as stated in above post.
They need to be closer together, the gap between them is too big.
Good job on the Mounting Bar and the overall setup, good wiring practices.
Luck,
