I had hoped the relays would have solved my issues though.
Relays will stop a good switch going bad. But it that on/off switch is the original one it probably has already gone bad which is what we suspect would cause your issue. The dimmer switch only effects the dash lighting.
The foot switch might be at fault but they are more robust. Usually it is the fault of the off/on switch. If it is the dash as well as the headlights flickering then it is the off/on switch for sure.
