Bronco 2021 lights losing power/voltage

[0ri0n]

Hi Good Day to everyone,

I put on the traxxas 9290 light kit on my bronco.

my issue is when turning the signal On or breaking or even just turning the park lights On the Headlights are dimming it seems losing voltage.

While the the turn signal is blinking, the headlights also dim blinking. even I placed light bar and fog lights. the light bar and fog lights also dimming.

Do I need to install BEC?

I need help.

Thanks.
