Each to their own.
I consider lights as a bit of a consumable, if they break the do not hurt anyone or cause damage to your vehicle (obviously with some exceptions, if i was doing a round AUS trip my opinion would differ).
I am new to the 4X4 world, and i figured that i could spend more money on quality things like a bull bar, lift kit, engine mods etc. all things that if they broke because they are cheap and nasty would either leave me stranded, cause an accident or possibly kill me.
I have a tight budget so i direct my funds to things i think a a better priority, lights were at the bottom of my list. Everyone has different needs and different budgets, these suited mine.
If/when my budget grows enough to justify spending top dollar on ALL aspects of my ute, then i will be buying top notch lights. But for the moment, if it gets the job done and does not cause damage to myself, my car and anyone else on the road then i will buy cheap, if it breaks in 2 months, lesson learnt, no harm done.
