I recommend you update the headlights to LED as well. You will find most LED tail light bulbs are made to work on 6&12v supplies, so when you have the halogen headlights on the voltage drops down to the low end of the lLEDs working range.

I suggest that you run the engine at a speed to give you a good charge with lights off, and maimtaining that speed check the voltage at the battery and at the rearlamps. If the voltage at the rearlamps is appreciably lower you know that there is resistance somewhere in the switch or the wiring. If that is the case, turn off the engine, and with the lights still on check the voltage to a good earth at all connection points between the battery and the rearlights. Old wires can have broken strands and connections can have resistance due to dirt and corrosion. Incidentally the voltage during running will be slightly higher in the Winter than the Summer position, and the state of the battery has considerable influence on dynamo output voltage, with load of any sort reducing the voltage.
