I have added 2 55 watt rectangular hella lights to the front of my 92 Mazda Navajo they are spliced into my highbeam wireing so they will come on when I turn on my highbeams the first trip they worked fine now when I turn them on after 5 mins my lights are flashing on and off first the hellas then my highbeams and finally they just shutdown till I turn the switch off and back on if anyone could tell Me how to resolve this if be greatly appreciative
