The horn sounds when he makes 206+ selectors

Hello everyone. When I turn on the high beams in my car or when I turn on the headlights, the horn sounds for a long time. I had my vehicle last engine washing, interior washing and I had an apparatus installed to control the pioneer tape from the steering wheel. a place you know and how much does it cost?

Probably the problem with the headlight signal lever bro. Please do not make every pouch to wash the engine, especially when washing at close range with pressurized water and washing the interior, such problems can occur if you are not careful.
