Any after market indicator warning buzzer with high impedance trigger, which I assume most are, should be fine with the BCU. Only issue would be need for diodes in left and right feeds to keep indicators electrically independent.

FWIW have the same issue but have disciplined myself to cancel them - usually blush. Noting the neutral angle of the indicator stalk helps.
