A bozo on the bus
But you have to be careful when you tap into one of the circuits, if there's a sufficient drop in voltage from the new lights, the system thinks one of the bulbs is out and runs the other at half brightness. Depends on the drain of the new lights.
Since most LED lights only consume fractions of an amp.. vs the filament bulb they're hooked in parallel with, that shouldn't really be a concern. More of a concern is the more elaborate ones having a controller for flashing them that isn't happy with 1/2 voltage if a filament burns out and the ZFE reduces the voltage by half to dim the remaining light (to function as a running light.) BTDT and the smoke came out. Took a while to figure out why..
