From a short while on, after getting my new 'Fire back in '96, my driver side headlight sometimes delays coming on with the passenger side one for up to a half second. This only happens when the lights get switched on from full off. It doesn't seem to be caused by the bulb inside it. It also does not happen if the lights are switched on to high beam to begin with. Anyone else of you have a similar 'problem'? Thankfully, this is not a serious condition, just an irksome annoyance.
Sounds like a bad ground on that light. Check your wireing
Semper Fi SAINT. May you rest in peace.
