he had extremely love towards me ,
(my brother and mother were almost next)

i have this issue . the bike (motorbike) i have a hero honda splendor
was bought by him in the year 1996 .

i hope the upcoming incident happens around 4 or more months .

after the sunset the vehicle's high beam is enabled though we don't change it, we are not disturbed or cursed by any evil activities because my brother is a severe hanuman devotee and his wife (my sister in law too) they have a daughter going to be aged one soon .

i am not afraid or scared .

i want to know who turns the vehicle's lights-high beam
(blue display in the vehicle's console) .

is it my father's spirit (roaming due to family bonding)

is it possible to fix this issue forever or know why it happens .

this truth is ignored by my family they don't believe in
paranormal activities .
